In this work, isothermal circular strand-displacement polymerization amplification assay is developed for highly specific and sensitive detection of adenosine triphosphate (ATP). The amplification process consists of circular common target molecule-displacement polymerization (CCDP) and circular nucleic acid strand-displacement polymerization (CNDP). In the(More)
A novel quartz crystal microbalance (QCM) assay was described for sensitive detection of protein. Lysozyme was used as a model of protein. To enhance the sensitivity of this QCM biosensor, biocatalytic precipitation (BCP) reaction combined with strand-scission cycle and rolling circle amplification (RCA) were applied together for the first time. As a result(More)
A novel biosensor was developed based on the cation-exchange of CuS nanoparticles (NPs) and Cu(i)-based click chemistry of functionalized gold nanoparticles (AuNPs). As a proof-of-principle, novel applications of this method as a versatile biosensor for single-nucleotide polymorphisms (SNPs) and DNA methyltransferase (MTase) were presented.
A new photoelectrochemical (PEC) biosensor was developed using low-toxic Ag2S QDs as photoelectrochemically active species. Energy levels of Ag2S and Ag2Se QD were compared to explain their differences in the PEC performance. The preparation condition of Ag2S QD was optimized and its structure characterization was measured. Then the developed photoelectric(More)
