Chromogenesis-based Resonance Raman molecular sensor for reactive oxygen species

Bandgap Engineered Polypyrrole–Polydopamine Hybrid with Intrinsic Raman and Photoacoustic Imaging Contrasts

“…36,37 However, existing RRS probes are mainly small molecules in the visible region. 38 These probes are not suitable for in vivo applications because the penetration depth of visible light is only a few micrometers. For the SiO 2 −CS@PPy−PDA nanoparticle, the absorption band of electron transition is located in the near-infrared region with a few millimeters of penetration depth.…”

“…By contrast, RRS originated from the resonance effect between the incident light and the electron transition energy. Moreover, RRS does not require noble metal substrates. , However, existing RRS probes are mainly small molecules in the visible region . These probes are not suitable for in vivo applications because the penetration depth of visible light is only a few micrometers.…”

Ratiometric analysis of reversible thia-Michael reactions using nitrile-tagged molecules by Raman microscopy

“…[2][3][4][5] To date, applications of Raman tags have been limited to molecular localization analysis, and the potential applicability of obtaining structural information and monitoring dynamic chemical equilibrium states has scarcely been explored. [6][7][8][9][10][11][12][13][14][15][16][17][18] In 2014, we performed structure-based Raman imaging to simultaneously visualize ionic and molecular forms of a bioactive small molecule, an uncoupler carbonyl cyanide p-trifluoromethoxyphenylhydrazone (FCCP), for the first time in live cells. 19 Based on this precedent, we aimed to apply Raman tags to analyze the dynamic chemical equilibria of small molecules formed via covalent bonds in live cells.…”

An Efficient Synthesis of New 2-Aryl-5-phenylazenyl-1,3,4-oxadiazole Derivatives from N,N'-Diarylcarbonohydrazides

“…However, this methodology often requires very specific reaction conditions, including low temperatures, narrow pH range (adjusted by combination of acids or buffers), and prolonged reaction times. [34][35][36] In the literature, several other methods for the preparation of simple azo compounds are described, includ-A. Kędzia et al…”
