Immunodetection chip, device and system and preparation method of immunodetection chip

Abstract

The invention provides an immunodetection chip, device and system and a preparation method of the immunodetection chip. An organic boom phototransistor is adopted in the immunodetection chip, and the immunodetection chip comprises a phototransistor, an antibody-coated backboard and a microfluidic module integrated between the organic phototransistor and the antibody-coated backboard, wherein the antibody-coated backboard comprises a backboard body, electrodes arranged on the backboard body and antibodies arranged on the electrodes, an organic phototransistor is adopted as the phototransistor, and the microfluidic module is used for completing the immunodetection process. Detection at the bedside of a patient or at home of the patient can be achieved, a professional clinical examiner is not needed for examination, an examination and analysis result can be quickly obtained on the site immediately, and complex treatment and analysis in a specialized laboratory are not needed.

Description

technical field [0001] The present application relates to an immunodetection chip, system and preparation method based on a water gate organic phototransistor, in particular to an immunodetection chip, device, system and preparation method of a water gate organic phototransistor that can be coated with antibodies. . Background technique [0002] Chemiluminescence immunoassay is a highly sensitive immunoassay method, and is widely used in automatic immunoassay instruments. Traditional instruments based on chemiluminescence immunoassay are expensive, complicated to operate, and bulky, and are suitable for hospitals, inspection institutions, etc. POCT (point-of-care testing, instant test) is an emerging in vitro diagnostic industry segment. POCT instruments are small in size, low in price, and easy to operate. They can be tested at the patient's bedside or at the patient's home without Professional clinical laboratory technicians are required to carry out the test, and the te...
