Bioreceptorbased

Bioreceptorbased refers to technologies or systems that utilize bioreceptors as their primary sensing element. A bioreceptor is a biological molecule or material that can specifically recognize and bind to a particular target analyte. This recognition event is then transduced into a measurable signal, allowing for the detection and quantification of the analyte. The selection of the appropriate bioreceptor is crucial for the specificity and sensitivity of the biosensor.

Common types of bioreceptors include antibodies, enzymes, nucleic acids (DNA and RNA), aptamers, and whole cells or tissues. Antibodies are highly specific for their corresponding antigens, making them excellent for detecting proteins, pathogens, and small molecules. Enzymes can catalyze reactions with specific substrates, and the resulting change in product concentration or enzyme activity can be measured. Nucleic acids can be designed to hybridize with complementary sequences, useful for detecting genetic material or specific RNA molecules. Aptamers are short, single-stranded DNA or RNA molecules that can bind to specific targets with high affinity and specificity, similar to antibodies but often more stable.

Bioreceptorbased systems are employed in a wide range of applications, including medical diagnostics for disease detection, environmental monitoring for pollutants, food safety testing for contaminants, and industrial process control. The development of advanced bioreceptorbased technologies continues to drive innovation in sensitive and selective analytical methods across various scientific and technological fields.
