Part III

Biosensing Technologies for Protein Assay In this last part, we will mainly discuss how to convert the signals of molecular recognition into readable signals, that is, biosensing technologies, which mainly include various technical means of commonly used electrochemistry and spectrometry. It also includes some less common technologies that are also reported and applied. How to convert these readable signals into digital signals through certain electronic devices will not be discussed. In this part, electrochemical technology is relatively complicated because of its system and principle, so we will mainly introduce the electrochemical technology itself, and illustrate the application of electrochemical technology in different protein biosensing systems. In terms of spectrometric technology, the principle is relatively simple, but nanomaterials play a crucial role in the output of spectrometric signals, so we will mainly introduce the spectrometric signal output that nanomaterials participate in. For other relatively unpopular technical means, we only give brief introductions and examples. Finally, since signal amplification is critical in the analysis of low-abundance samples, we will present some commonly used signal amplification techniques in a separate chapter.
