A general highly efficient synthesis of biocompatible rhodamine dyes and probes for live-cell multicolor nanoscopy

open access: yesNature Communications, 2023
Rhodamines are privileged fluorescent dyes for labelling intracellular structures in living cells. Here, the authors present a facile protecting-group-free synthesis permitting generation of a wide range of symmetrical and unsymmetrical 4 ...

A General Method to Develop Highly Environmentally Sensitive Fluorescent Probes and AIEgens

open access: yesAdvanced Science, 2022
Environmentally sensitive fluorescent probes (including AIEgens) play pivotal roles in numerous biological studies. Many of these functional materials are developed based on the twisted intramolecular charge transfer (TICT) mechanism.

Modification of Graphitic Carbon Nitride with Hydrogen Peroxide

open access: yesNanomaterials, 2020
Graphitic carbon nitride (GCN) was synthetized by heating melamine and then it was thermally exfoliated for 1–3 h in air. Both bulk and exfoliated GCN nanomaterials were treated in the 10–30% aqueous solutions of H2O2 for us to study their modification ...

New Supramolecular Hypoxia-Sensitive Complexes Based on Azo-Thiacalixarene

open access: yesMolecules, 2023
Hypoxia accompanies many human diseases and is an indicator of tumor aggressiveness. Therefore, measuring hypoxia in vivo is clinically important. Recently, complexes of calix[4]arene were identified as potent hypoxia markers.
