RETRACTED: Monitoring of Sports Health Indicators Based on Wearable Nanobiosensors (Retracted article. See vol. 2022, 2022)

Biosensors are instruments that are sensitive to biological substances and convert their concentration into electrical signals for detection. Generally speaking, there are two main means to promote health: one is medical intervention, and the other is exercise intervention. Medicine is mainly the second half of the health decay of the whole person, that is, disease treatment and control, while exercise intervention is mainly to prevent and promote the first half of the health decay. The purpose of this paper is to study the biochemical properties of nanomaterials and the exercise health of the elderly. In this paper, an electrochemical research method for detecting the kinase activity of polynucleotides by streptavidin-gold nanoparticles and enzyme amplification is proposed based on the thermophysical properties of materials and the properties of nanoparticles. The experimental results show that, compared with the traditional electrochemical method, the method has the advantages of simple operation, high sensitivity, and high selectivity, its linear range is from 0 U/mL to 5 U/mL, and the detection limit is 0.01 U/mL. In contrast, AgNWs cotton fiber films exhibited lower volume resistivity. The experimental design of this paper provides a theoretical and practical basis for researchers and has great research significance for the innovative research and development of nanomaterials.
