Being awfully harmful to the environment and human health, the qualitative and quantitative determinations of polycyclic aromatic amines (PAAs) are of great significance. In this paper, a novel core–shell heterostructure of multiwalled carbon nanotubes (MWCNTs) as the core and graphene oxide nanoribbons (GONRs) as the shell (MWCNTs@GONRs) was produced from longitudinal partially unzipping of MWCNTs...
We report on a novel mercury(II)-controlled approach for the disassembly of gold nanorods (AuNRs) that has led to a detection system for Hg(II). The modified AuNRs were fabricated by functionalizing AuNRs with L-cysteine via a thiol group chemisorption-type of interaction. L-cysteine induces the assembly of AuNRs through cooperative electrostatic interaction upon which the color of the solution of...
