Near‐Infrared Light‐Driven Zn/Au Janus Micromotors for Multiplex SERS Detection of Anticancer Drugs

open access: yesAdvanced Functional Materials, EarlyView.
Zn/Au Janus micromotors, propelled by thermophoretic effects under NIR light, function as active SERS platforms for single and multiplex detection of anticancer drugs. Their dynamic motion enhances analyte exchange at the Au interface, reducing saturation and competitive adsorption, thereby improving sensitivity and extending the linear detection range.

Atmospheric Corrosion of Silver and Silver Nanoparticles

open access: yesCorrosion and Materials Degradation, 2022
Even though it is a noble metal, silver will corrode in ambient atmospheres, predominantly by reacting with sulfur-containing gases such as hydrogen sulfide (H2S) and carbonyl sulfide (OCS) to form the silver sulfide (Ag2S) acanthite. Other aspects of the environment, such as relative humidity and the presence of oxidizing species, also play a critical
