Selective detection of gas-phase TNT by integrated optical waveguide spectrometry using molecularly imprinted sol–gel sensing films

Poly(p‐phenylene ethynylene) Incorporating Sterically Enshrouding m‐Terphenyl Oxacyclophane Canopies

“…While reversibility is advantageous in some applications and assists in sensor reusability, there are also instances in which irreversibility is preferred, so availability of both types of sensors is desirable. [43] Encouraged by the DNT result, we repeated the experiment with TNT vapor. The rate enhancement of P1 (35 min required to achieve maximum quenching) versus P2 (300 min to maximum quenching) to TNT vapor (10 ppb) was less than the enhancement observed for DNT ( Figure 2B, right).…”

Preparation and Catalytic Performances of a Molecularly Imprinted Ru‐Complex Catalyst with an NH2 Binding Site on a SiO2 Surface

“…Yield: 0.34 g (1.7 mmol, 68 %). Synthesis of a chiral template with a binding moiety (C): [101] Isocyanatopropyltriethoxysilane (0.27 g, 1.1 mmol) and pyridine (0.07 mL) were added to a solution of chiral o-hydroxybenzhydrol (0.20 g, 1.0 mmol) in anhydrous THF (5 mL) under N 2 atmosphere. The mixture was refluxed for 2 days and then the solvent was removed under vacuum.…”

Layer-by-layer assembled DNA-functionalized single-walled carbon nanotube hybrids-modified electrodes for 2,4,6-trinitrotoluene detection

“…1 shows the AFM image of individually dispersed bead-string-like structure of SWCNTs, indicating the wrapping of DNA along SWCNT sidewall. The mechanisms for the adsorption of TNT and related nitroaromatic compounds onto other matrixes have been widely studied [11,[29][30][31]. The formation of a p-electron donor-acceptor complex and hydrogen bond of TNT to other binding sites both are the mechanisms for the adsorption of TNT [11,29].…”
