摘要

一个大毫米宽的电子界面可以检测到单分子/实体的检测极限。这项技术被称为SiMoT——单分子大晶体管。到目前为止,已经检测到抗原(免疫球蛋白、c反应蛋白、spike1、HIV p-24)、抗体(抗免疫球蛋白、抗spike1)、多肽、病毒(SARS-Cov-2)、细菌(木杆菌),甚至DNA链(KRAS、miR-182)。通过将大量(1011-1012/cm2)的识别元件覆盖在栅极上,以亲和性结合目标元件,从而保证了选择性。

Single-protein large area detections: from mechanism to applications in the clinics
A large millimeter-wide electronic interface can detect at a single-molecule/entity limit-of-detection. The technology is called SiMoT - Single-Molecule with a large Transistor [1]. So far, antigens (Immunoglobulins, C-reactive proteins, spike 1, HIV p-24), antibodies (anti-immunoglobulins, anti-spike1), peptides, viruses (SARS-Cov-2), bacteria (Xylella fastidiosa), and even DNA strands (KRAS, miR-182) have been detected. Selectivity is assured by covering the gate electrode with a large number (1011-1012/cm2) of recognition elements to affinity binding the target element.
