In this work, a 2-(2-hydroxyphenyl)benzothiazole (HBT)-based ratiometric fluorescent probe exhibiting coupling between the ICT and ESIPT mechanisms was exploited for the optical sensing of cysteine and successfully utilised in the bio-imaging of cysteine in HeLa cells.

Abstract Micronuclei are small nuclear cellular structures containing whole chromosomes or chromosomal fragments. While there is a lot of information available about the origin and formation of micronuclei, less is known about the fate of micronuclei and micronucleated cells. Possible fates include extrusion, degradation, reincorporation and persistence. Live cell imaging was performed to quantitatively analyse the fates of micronuclei and micronucleated cells occurring in vitro. Imaging was conducted for up to 96 h in HeLa-H2B-GFP cells treated with 0.5, 1 and 2 µg/ml etoposide. While a minority of micronuclei was reincorporated into the main nucleus during mitosis, the majority of micronuclei persisted without any alterations. Degradation and extrusion were observed rarely or never. The presence of micronuclei affected the proliferation of the daughter cells and also had an influence on cell death rates. Mitotic errors were found to be clearly increased in micronucleus-containing cells. The results show that micronuclei and micronucleated cells can, although delayed in cell cycle, sustain for multiple divisions.

The sensing behaviour of benzimidazole and thiozole derivatives from heteroaromatic aldehyde was studied towards various cations and anions. S1 showed selectivity towards Cr3+ with fluorescence enhancement and live cell imaging of Hela cells was successfully demonstrated.
