Biosensors for Detecting Lymphocytes and Immunoglobulins

Area of Science:

• Immunology and biosensor technology.

Background:

• Lymphocytes (B, T, NK cells) and immunoglobulins are vital for adaptive immunity.
• Current detection methods (flow cytometry, ELISA, impedance) have limitations for point-of-care applications.
• Biosensors present a potential solution for fast, low-cost, and reliable detection.

Purpose of the Study:

• To review biosensor fabrication methods for detecting lymphocytes and immunoglobulins.
• To discuss various measurement techniques and transducers used in biosensors.
