A biosensor consists of the array of nanorods of metal that are positioned on the substrate. A reservoir is constructed between the substrate and an electropolymerized conducting conductor by placing a portion of the nanorods on top it. The pores of the electropolymerized conductor sensitive to electrical signals. Dispensing materials are placed in the reservoir to be dispersed in accordance to open pores.

Technical Field

The invention is generally related to biosensing equipment, and more specifically, devices and methods to control molecular interactions at a device electrode through the release of inhibitors to stop biofouling, or to release growth factor tocontrol cell growth.

Description of Related Art

Biosensors can utilize electrodes to determine the properties of materials as well as to draw attention to substances being measured or sensed. Electrodes employed on biosensors need protection to prevent competing molecules from reacting at the electrodes.Biosensors are useful for detection of neural activity, such as voltage changes around active neurons or the concentration levels of neurotransmitters. Biosensors may have a limited life in vivo because of the possibility of electrochemical fouling due to cellular material accumulation or immune system attack.

In accordance with the embodiment of the invention a biosensor includes the array of metal nanorods placed on a substrate. A conductor that is electropolymerized is formed over tops of at least a portion of the nanorods to form a reservoir between the electropolymerized conductor and the substrate. The electropolymerized pores conductor are responsive to electrical signals. The reservoir is filled with a dispensing material to disperse according to open pores.

Another biosensor consists of an array of metal nanorods arranged on a substrate, with the array of metal nanorods is placed into a first and a separate region. The first area has a first spacing among the nanorods so that an electric field not compatible with cell activity can be created upon activation. The second area has a second spacing between the nanorods so that upon activation , an electrical field in line with the activity of cells is produced.

A method for making a biosensor includes forming nanorods in a layer of metal and forming a conformal layer over the nanorods, and recessing the conformal layer onto at least a portion of the nanorods, and then electropolymerizing the conductor over the nanorods exposed by recessing to form a reservoir between an electropolymerized conductor as well as the metal layer the conductor is electropolymerized and has pores that open and close responsively to electrical signals that are applied to the nanorods and loading dispensing material to be dispersed in the reservoir according to the open pores.

What is a patent?

Patents are granted by the government to protect the invention. It gives the inventor the exclusive right to create, use and market the invention. Society gains when new technologies are brought to market. Benefits can be realized in direct terms, as it can allow individuals to achieve previously unattainable things, or indirectly, through the economic opportunities (business expansion and job creation) that the innovation offers.

Patent protection is demanded by many university researchers and drug companies for their research and development. Patents may cover an abstract or physical process or product, or even a method or composition of materials new to the field. In order to be granted protection under a patent, an invention must be novel, useful and not be obvious to anyone else within the same subject.

Patents are a way to give inventors a reward for commercially profitable inventions. They are an incentive to inventors to create. Small companies and inventors can be sure that they will earn the most return from their investment in technology advancement through patents. They can earn a living from their work.

Patents are essential to companies, and they can:

Secure innovative products and services;

Increase the visibility and value of your products ‘ presence on the market

Your business and your products should be distinguished from others;

Get business and technical details.

Avoid the danger of using third-party proprietary content or losing important information, creative outputs, or other creative output.

Patents transform inventors’ knowledge into a marketable asset which opens new opportunities for employment creation and expansion of businesses through licensing or joint ventures.

Small-scale businesses with patent protection are more attractive to investors involved in the commercialization and development of technology.

Patents can result in new ideas and inventions. The information you create may be protected by patents.

Patents can be used to serve as an obstacle to unscrupulous third parties that profit from the efforts of an invention.

Patent-protected technology that is commercially profitable could be used to fund technology-related research and development (R&D), which can increase the chance of a better technology in the near future.

It is possible to use intellectual property ownership to convince lenders and investors that your product has real commercial potential. Sometimes, one powerful patent could open the door to multiple financing opportunities. Patents as well as other IP assets can be utilized as collateral or security for financing debt. Investors can also see your patent assets in order to boost their valuation of your company. Forbes and others have pointed out that each patent can increase between $500,000 and one million dollars to company valuation.

Startups require a carefully-crafted business plan that leverages the IP to show that your product/service is distinct, superior, or innovative. In addition, investors will be impressed when you prove that your IP rights are secured or are in the process of becoming secure and that they align with your business plan.

It is important to keep an invention secret until you submit for patent protection. Public divulging an invention could frequently devalue its originality and render it invalid. Disclosures that are filed prior to filing, like for investors, test-marketing or any other business partners, must be done following the signing of a confidentiality agreement.

There are a variety of patents, and understanding them is essential to protecting your invention. Utility patents cover new processes and machine creations. Design patents cover ornamental designs. Patents for utility are the most effective since they shield the owner from copycats as well as other competition. Frequently, utility patents are issued for alterations or improvements to existing inventions. Utility patents can also be used to cover improvements and modifications to existing inventions. A process patent would describe the methods or actions of performing a particular act. But, a chemical composition could be a combination of components.

What is the length average of patents? While utility patents are valid up to 20 years from their initial filing, they can be extended by delay at the patent office.

Are you interested in finding other similar patents? These are the steps to follow:

1. Brainstorm terms that describe your invention, based on its intended purpose, composition and application.

Write down a short detailed description of the invention. Don’t use generic terms such as “device”, “process” and “system”. Instead, think about synonyms for the terms you selected initially. Then, note important technical terms, as well as keywords.

To help you identify the key words and concepts, try the following questions.

  • What’s the purpose of the invention? Is it a utilitarian device or an ornamental design?
  • Is the invention a method of creating something, or performing an action? Are you referring to an item?
  • What is the nature and purpose of the invention? What is the physical structure?
  • What is the goal of the invention
  • What are the technical terms and keywords that describe the essence of an invention? A technical dictionary can help you locate the right terms.

2. Utilize these terms to locate relevant Cooperative Patent Classifications on the Classification Text Search Tool. To find the best classification to your invention, look through the classification’s class Schemes (class schedules). If you don’t get any results from the Classification Text Search, you may want to consider replacing the words to describe your invention with synonyms.

3. Review 3. Go over the CPC Classification Definition to determine the relevancy of the CPC classification you’ve found. If the chosen classification has a blue box with a “D” at its left, the link will direct you to a CPC classification description. CPC classification definitions can aid you in determining the classification’s scope , so you can select the most appropriate. Furthermore they can provide search tips and other suggestions which could be helpful for further investigation.

4. Find patent documents that have the CPC classification from the Patents Full-Text and Image Database. By focusing on abstracts and illustrations it is possible to narrow your search for the relevant patent documents.

5. Take advantage of this list of most relevant patent publications to look at each in detail for similarities to your invention. Pay attention to the specification and claims. Refer to the applicant and patent examiner for any additional patents.

6. You can find published patent applications that meet the CPC classification you selected in Step 3. You may also employ the same search strategy that you employed in Step 4 to narrow your search results down to just the most relevant patent applications by looking over the abstracts and representative drawings for every page. Next, examine all published patent applications carefully and pay particular attention to the claims as well as other drawings.

7. Locate additional US patents by keyword searching in PatFT or AppFT databases, searching for classification of non-U.S. patents as per below, and searching non-patent literature disclosures of inventions using web search engines. For instance:

  • Add keywords to your search. Keyword searches may turn up documents that are not well-categorized or have missed classifications during Step 2. For example, US patent examiners often supplement their classification searches with keyword searches. Think about the use of technical engineering terminology rather than everyday words.
  • Search for foreign patents using the CPC classification. Then, re-run the search using international patent office search engines such as Espacenet, the European Patent Office’s worldwide patent publication database of over 130 million patent publications. Other national databases include:
  • Search non-patent literature. Inventions can be made public in many non-patent publications. It is recommended that you search journals, books, websites, technical catalogs, conference proceedings, and other print and electronic publications.

To review your search, you can hire a registered patent attorney to assist. A preliminary search will help one better prepare to talk about their invention and other related inventions with a professional patent attorney. In addition, the attorney will not spend too much time or money on patenting basics.
