Shоrt essаy (100-200 wоrds, 8-12 sentences, 1-2 pаrаgraphs) A restaurant is having issues with Pathоgen X contaminating their food and customers are getting sick, especially those that asked for lettuce on their burrito. The restaurant needs to develop a new immunoassay to detect Antigen Y from Pathogen X in their lettuce. The clinically relevant range of Antigen Y is 1 picomolar (pM) – 1 nanomolar (nM), meaning that is the range of concentrations that Antigen Y is found in the lettuce. They hire you as an immunoassay expert to design the immunoassay, and you decide to design a biosensor to detect Antigen Y. For the biosensor design… What kind of sample will you use as an input into your biosensor? What would be an appropriate bioreceptor for this biosensor? Why did you choose that bioreceptor? What electrical interface would you use that transduces the bioreceptor binding to Antigen Y into a signal? Describe your electronic system that converts the electrical signal into a readable result. Your engineering team produces an alpha prototype of the biosensor that can detect Antigen Y from 1 millimolar (mM) – 1 molar (M). Is this detection range useful, or should you change the design of your prototype? If this detection range is not useful, suggest any changes or modifications to the alpha prototype you would make. The alpha prototype is also quite large and bulky. Please make a suggestion to the engineering team about a microfluidic platform they can use to miniaturize the biosensor.
