The shape-controlled synthesis of gold nanocrystals via shape induction of hexadecyltrimethylammonium chloride, potassium bromide, and potassium iodide and enantioselective direction of L-cysteine is reported. The resulting gold nanocrystals (STO-Au) offer spiny trisoctahedron nanostructures with good monodispersity and enhanced exposed high-index facets and high catalytic activity. Construction of the electrochemical sensing platform for MON89788 gene involves the modification of STO-Au, thionine (Thi), and labeled bipedal DNA probe 1 or 2 (P1 or P2) for target DNA-induced recycling amplification.

Article Synopsis
- - The study focuses on a new method for detecting acetamiprid using D-penicillamine and histidine-functionalized graphene quantum dots (DPA-GQD-His) combined with a G-quadruplex DNAzyme, which enhances the sensitivity of detection.
- - The detection process involves the formation of a G-quadruplex structure that releases a specific DNA probe upon acetamiprid binding, ultimately leading to a fluorescent reaction that can be measured.
- - This method shows impressive sensitivity, with a detection limit of 0.38 fM and the capability to detect acetamiprid across a concentration range from 1.0 fM to 1.0 nM, demonstrating effective application in

Graphene and its derivatives have been demonstrated to be good surface-enhanced Raman scattering (SERS) substrates. However, the literature offers some contrasting views on the SERS effect of graphene-based materials. Thus, understanding the mechanism of the SERS enhancement of graphene is essential for exploring its application as a SERS substrate.
