Int J Biol Macromol 2023; 239:124261. [PMID: 37003383 DOI: 10.1016/j.ijbiomac.2023.124261] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2022] [Revised: 03/15/2023] [Accepted: 03/27/2023] [Indexed: 04/03/2023]
Abstract
As one of the most abundant metal ions, Cu2+ has turned into a great threat to human health and the natural environment due to its widely utilized in various industries. In this paper, a chitosan-based fluorescent probe CTS-NA-HY for detection and adsorption of Cu2+ was rationally prepared. CTS-NA-HY exhibited a specific "turn off" fluorescence response to Cu2+ and the fluorescence color changed from bright yellow to colorless. It possessed satisfactory detection performance to Cu2+ including good selectivity and anti-interference, low detection limit (29 nM) and wide pH range (4-9). The detection mechanism was confirmed by Job's plot, X-ray photoelectron spectroscopy, FT-IR and 1H NMR analysis. Additionally, the probe CTS-NA-HY was capacity of determining Cu2+ in environmental water and soil samples. Besides, CTS-NA-HY-based hydrogel could also remove Cu2+ in aqueous solution effectively, which the ability of adsorption was greatly improved compared with original chitosan hydrogel.

[PMID: 34637183 PMCID: PMC8507439 DOI: 10.1002/open.202100104] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2021] [Revised: 09/10/2021] [Indexed: 11/24/2022] Open
Abstract
A smart fluorescence "turn-on" probe which contained a dansyl amide fluorophore and an N-oxide group was designed based on the bioorthogonal decaging reaction between N-oxide and the boron reagent. The reaction proceeds in a rapid kinetics (k2 =57.1±2.5 m-1 s-1 ), and the resulting reduction product showcases prominent fluorescence enhancement (up to 72-fold). Time dependent density functional theoretical (TD-DFT) calculation revealed that the process of photoinduced electron transfer (PET) from the N-oxide moiety to the dansyl amide fluorophore accounts for the quenching mechanism of N-oxide. This probe also showed high selectivity over various nucleophilic amino acids and good biocompatibility in physiological conditions. The successful application of the probe in HaloTag protein labeling and HepG2 live-cell imaging proves it a valuable tool for visualization of biomolecules.
