Novel Optical Nanoprobes for Chemical and organic Analysis starts off with a quick advent to numerous sorts of flexible nanomaterials with novel optical houses, comparable to gold/silver nanoparticles, quantum dots, upconversion nanoparticles and graphene. It almost always makes a speciality of the most recent sensor layout suggestions, which follow the optical homes of nanomaterials to varied detection concepts together with colorimetry, fluorescence, and surface-enhanced Raman scattering (SERS). those sensors are appealing as a result of their excessive sensitivity, excessive specificity, and strength for simple quantification of pursuits in lots of purposes, akin to traditional chemical and organic research, scientific analysis, and intracellular procedure sensing in addition to single-molecule detection. The demanding situations and destiny views for optical nanoprobes also are awarded, comparable to the rise in sensitivity for actual environmental and scientific samples, the layout and alertness of multifunctional nanoplatforms, and biocompatibility of nanomaterials.

Developed a similar method for Hg2+ detection using mercaptopropionic acid-modified Au NPs in the presence of 2, 6-pyridinedicarboxylic acid [47]. For colorimetric Hg2+ detection, the specific affinity between thymine (T) and Hg2+ has been a considerable recognition moiety. Dependent on T–Hg2+–T coordination chemistry, the colorimetric assay for Hg2+ was first developed by the Mirkin’s group based on a complementary DNA-Au NP system with designed T–T mismatches [46]. As shown in Fig. 15A, two types of nanoparticles aggregated together after the specially designed ssDNA hybridized, causing a red-to-purple color change.
