Gold and silver nanoparticles (Au/AgNPs) are widely used in analytical chemistry, and their
intense colors have inspired artists and fascinated scientists. This review describes the …

There is little doubt that nanoparticles offer real and new opportunities in many fields, such
as biomedicine and materials science. Such particles are small enough to enter almost all …

Methods based on sandwich-type electrochemical enzyme immunoassay protocol have
been extensively developed for the detection of biomolecules, but most often exhibit low …

Single-strand DNA (ssDNA) was used to modify 10 nm nanogold to obtain an aptamer-
modified nanogold resonance scattering (RS) probe (AussDNA) for detection of Hg2+. In the …

Procalcitonin, as a medium of inflammation, has become a new marker of the identification
of severe bacterial infections in recent years and has received high attention due to its most …

DNA-functionalized gold nanoparticles are shown to act as a light-scattering switch. Ag+ ion
turns on the switch through the DNA–Au NPs conjugates based on the formation of cytosine …

Abstract Prostate-specific antigen (PSA), as the specificity of prostate cancer markers, has
been widely used in prostate cancer diagnosis and screening. In this study, we fabricated an …

Light scattered from nanoparticles (NPs) can easily be observed by the naked eye. Light-
scattering signals from nanomaterials have been applied extensively for analysis (eg, in …

In the medium of EDTA− NaOH, nanogold strongly catalyzed the slow reaction between
hydrazine (N2H4) and Cu (II) to form Cu particles, which exhibited a strong resonance …

Gold nanoparticles (AuNP) have catalysis on the reaction of HAuCl4-H2O2. The produced
AuNP have strong resonance Rayleigh scattering (RRS) effect and surface-enhanced …
