Front Cover: A Simple Colorimetric Assay of Bleomycin‐Mediated DNA Cleavage Utilizing Double‐Stranded DNA‐Modified Gold Nanoparticles (ChemBioChem 1/2023)

An operationally simple colorimetric assay of hyaluronidase activity using cationic gold nanoparticles.

An operationally simple colorimetric way for measuring hyaluronidase activity was developed using cysteamine-bound gold nanoparticles. The addition of gold nanoparticles into hyaluronidase-containing solutions resulted in color changes, which could easily be observed with the naked eye or a UV/Vis spectrophotometer.

Colorimetric recognition of DNA intercalators with unmodified gold nanoparticles.

A colorimetric approach to recognize the binding mode between DNA and molecules was developed, which was based upon the electrostatic interaction between DNA and gold colloids.

Colorimetric biosensing of pathogens using gold nanoparticles.

Rapid detection of pathogens is crucial to minimize adverse health impacts of nosocomial, foodborne, and waterborne diseases. Gold nanoparticles are extremely successful at detecting pathogens due to their ability to provide a simple and rapid color change when their environment is altered. Here, we review general strategies of implementing gold nanoparticles in colorimetric biosensors. First, ...
