A novel liquid crystal resonance Rayleigh scattering spectral probe for determination of trace Cr6+

Antibody-labeled gold nanoparticle based resonance Rayleigh scattering detection of S100B

“…† It can be seen that the RRS spectra are located in the absorption band, and thus scattering can resonate with light absorption, resulting in a resonance-enhanced scattering effect, which is the main reason for the enhancement of RRS. 34,35 The Ab-AuNP probe can be assembled onto S100B by specic recognition of binding to S100B. As shown in Fig.…”

A new strategy for RRS-based determination of phosphate with a bifunctional Fe3O4 magnetic nanoparticle surface molecularly imprinted polydopamine probe

“…Cr 6+ can react with dibenzoyldihydrazide (DCB) to form a purple complex. Zhi 17 for the first time used ( trans , trans )-4-(3,4-difluorophenyl)-4-amyl bicyclohexane (DP) as an energy donor and purple complex as an acceptor to establish a new platform for Cr 6+ detection by means of RRS-ET. The DL can reach 0.49 nmol L −1 and It can react with p -amino-dimethylaniline (DMPD) to produce methylene blue (MB).…”

Construction of Effective Nanosensor by Combining Semiconducting Polymer Dots with Diphenylcarbazide for Specific Recognition of Trace Cr (VI) Ion in Water and Vitro

“…The typical DPC method is the colorimetric method [ 28 , 29 ], and the combination of DPC reagent and the other method has been also explored. Recently, Zhi et al reported a Rayleigh scattering spectral probe consisting of DPC and liquid crystal trans for Cr (VI) ion detection in aqueous solution [ 30 ]. However, to our knowledge, the DPC reagent has been barely utilized to construct fluorescent probes for sensing Cr (VI) ion.…”
