Abstract:

Visual detection technology is that generates optical signals in the visible region through the specific interaction between the targets and micro-nanoparticles or other materials, and then realizes the quantification of targets with the assistance of the naked eye or image processing technology. The application of visual detection technology in the field of bioanalysis can effectively reduce the detection cost, improve the low efficiency of biological detection, simplify the complicated operation steps, and solve the problems such as the need to use professional instruments. This work introduces the latest research progress of visual detection technology in the field of bioanalysis in recent 15 years. According to the detection principle, it can be classified into particle counting method, colorimetry method, liquid crystal sensing method, range signal method, and lateral flow test strip method. Finally, the advantages and challenges of visual detection technology are analyzed, and the future application prospects of visual detection technology in the field of bioanalysis are prospected.
