TL;DR: In this article, the toxicity of copper nanoparticles (CuNPs) was investigated based on a stress-responsive bacterial biosensor array, and it was found that CuNPs induce not only oxidative stress in E. coli, but also protein damage, DNA damage and cell membrane damage, and ultimately cause cell growth inhibition.

TL;DR: The repeatability test of extraction and chromatographic analysis was satisfactory for the analysis of these polyphenolic compounds and methanol produced a higher recovery than pure water as extracting solvent for these compounds.

TL;DR: In this paper, a novel method has been developed for analysis of N -nornuciferine, O-nornociferine and roemerine in leaves of Nelumbo nucifera Gaertn by using high-performance liquid chromatography (HPLC) and photodiode array detection (DAD) methods.

TL;DR: A new bio-mimetic quartz crystal thickness-shear-mode (TSM) sensor, using an imprinted polymer coating as the sensitive material, has been fabricated and applied to the determination of nicotine (NIC) in human serum and urine.

TL;DR: A modular strategy is presented for the construction of cell surface DNA-based sensors by engineering DNA motifs and synthetic cofactors, and a stimuli-reactive organic molecule is employed as the cofactor for the DNA motif, and the self-assembly of them forms a FRET-based holo DNA- based sensor.
