As cyanide ion (CN−), an ecologically harmful pollutant, has received incessant attention with growing industrialization on a global scale, the capability of on-site monitoring CN− contamination becomes increasingly crucial. In this work, we have fabricated simplistic plasmonic-sensing platform for CN−, which can be combined human naked eye visual monitoring. The main sensor part consisted β-Cyclodextrin (β−CD)-decorated gold-rich silver bimetallic alloy nanoparticles (β−CD-Ag/Au-rich NPs), while sensing analysis was performed by spectrophotometer or smartphone, where optical data gathered its camera were analyzed RGB color sensing. Upon introduction various quantities into β−CD-Ag/Au-rich NPs, spectral peak surface plasmon resonance (SPR) shifted from 488 nm to 496 nm. This redshift indicated strong etching reaction between NPs and demonstrating ultrahigh detection sensitivity, i.e., limit (LOD) 0.24 nM. During formation metal-cyano complexes in CN−-induced response observed naked-eye discernible change brownish-red colorless, allowing smartphone could also analyze colorimetric such process via sensing, LOD 1.35 nM, being still less than maximum concentration (1.91 nM) drinking water, is allowable World Health Organization (WHO). straightforwardness very high sensitivity proposed technique using may hold promise simplistic, affordable in-field examinations CN⁻ water.

The optical sensing of chirality is widely used in many fields, such as pharmaceuticals, agriculture, food, and environmental materials. In this context, the color-based cascade amplification chirality, coupled with chiral recognition for analytes, provides a low-cost straightforward detection method that avoids use expensive sophisticated instrumentation. However, realization using approach still challenging because construction three-dimensional site required to easily discern differences chirality. Therefore, considerable efforts have been dedicated developing hierarchical based on molecular organization provide colorimetric sensors detection. This review covers function-integrated responsive sites absorption, fluorescence, aggregation-induced emission enabled by organization. line approach, data-driven chemometrics useful quantitative accurate pattern recognition. Finally, nanomaterials are discussed, focusing platforms noble-metal nanoparticles, carbon dots, photonic crystal gels.
