A simple copper(ii) dppy-based receptor for sensing of l-cysteine and l-histidine in aqueous acetonitrile medium

Abstract

The development of simple yet efficient receptors that rapidly detect and monitor amino acids with high sensitivity and reliability is crucial for the early-stage identification of various diseases. In this...

A novel Salen-based dual channel sensor for easy and selective nanomolar detection of l-cysteine

“…64, the sensor is a relatively simple isatin-based sensor which offers a high level of detection limit (10 −11 M) but the sensor is a fluorescence-based one and it lacks the purity that the single crystal structure offers. However in another work, 65 a copper-based sensor is used for immediate sensing of l -Cyst at the micromolar level, but the crystalline form of the sensor is not yet established. In the case of another electrochemical sensor, 66 despite its capability to achieve nanomolar detection, the synthetic method involved is intricate.…”

Investigation of protein/DNA binding, and in vitro cytotoxicity of novel Cu(ii) and Zn(ii)-dipyrazinyl pyridine complexes

“…5–8 The biological applications of terpyridines also include DNA and protein binding. 5 The significance of terpyridines and their metal complexes extends to diverse areas, ranging from sensing, 9–11 self-assembly, 12–15 dye-sensitized solar cells, 16 and halogen bonding, 17,18 to organic light-emitting devices. 19 Like terpyridines, dipyrazinyl pyridines (dppy) are expected to possess comparable biological prowess due to their analogous NNN-pincer type structure and additional nitrogen atoms in the pyrazine moieties.…”
