This invention provides a perovskite with a modified surface and method for making the same. In one embodiment, said perovskite is a mixed-cation lead halide perovskite; and said modified surface comprises a DPGABr:PbIcomplex layer. In one embodiment, said method for manufacturing a perovskite with a modified surface, comprises the steps of: a) Providing a perovskite with a surface to be modified; b) Treating said surface to be modified with DPGABr; and c) Annealing to form said perovskite with a modified surface.

Perovskite with modified surface and method for making the same

The present technology for the detection and analysis of analytes within a sample is based on molecular biology methods, including western blotting, gel electrophoresis, mass spectrometry, enzyme-linked immunosorbent assays and RT-PCR, which are normally time-consuming and laborious. The present disclosure provides novel OECT based electrochemical biosensors that can enable the convenient and cost-effective determination of analytes within a sample with high sensitivity and selectivity.

Highly sensitive biomarker biosensors based on organic electrochemical transistors

A non-invasive glucose sensor () for detecting an amount of glucose in bodily fluid, comprising: an organic electrochemical transistor (OECT) having a gate electrode (); wherein a surface of the gate electrode () is modified with an enzyme and a nanomaterial to increase sensitivity and selectivity of the gate electrode ().

Non-invasive glucose sensor

An organic electrochemical transistor (OECT) that may be used as a biosensor is built up by layers applied to a monofilament. A first conducting layer applied to the monofilament includes generally cylindrical source and drain contacts with a gap therebetween. An electro-active layer of an organic material altering its electrical conductivity through a change in redox state is in electrical contact with the source and drain contacts, and has a transistor channel interface for contacting an electrolyte. A gate electrode is spaced apart from the first monofilament, and may comprise a cylindrical layer built up on another length of monofilament.
