carbohydrates+ testing for carbohydrates

Question 1

what are biosensors

Answer 1

biosensors use biological components todetermine the presence and concentration of glucose in a sample

Question 2

what is the mechanism of biosensors

Answer 2

-molecular recognition= aprotein (enzyme or antibody) or ssDNA single stranded DNA is immobilised to a surface for example a glucose testing strip this will interact with or bond to the analyte.
transduction=this interaction will cause a change in the transducer a transducer detects a change for example in ph and produces a response such as the release of an immobilised dye or an electrical current in a glucose testing machine
display-produces a visible quantitative and quantitative signal such as a reading on a test machine or a particular colour on a testing strip

Question 3

definition of analyte

Answer 3

the compound under investigation
