ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2021; 274:115681. [PMID: 33308872 DOI: 10.1016/j.envpol.2020.115681] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/19/2020] [Revised: 09/14/2020] [Accepted: 09/15/2020] [Indexed: 06/12/2023]
Abstract
Quantum dots (QDs) are nanoparticles of inorganic semiconductors and have great promise in various applications. Many studies have indicated that mitochondria are the main organelles for the distribution and toxic effects of QDs. However, the underlying mechanism of QDs interacting with mitochondria and affecting their function is unknown. Here, we report the mechanism of toxic effects of 3-mercaptopropionic acid (MPA)-capped CdTe QDs on mitochondria. Human liver carcinoma (HepG2) cells were exposed to 25, 50 and 100 μmol/L of MPA-capped CdTe QDs. The results indicated that MPA-capped CdTe QDs inhibited HepG2 cell proliferation and increased the extracellular release of LDH in a concentration-dependent manner. Furthermore, MPA-capped CdTe QDs caused reactive oxygen species (ROS) generation and cell damage through intrinsic apoptotic pathway. MPA-capped CdTe QDs can also lead to the destruction of mitochondrial cristae, elevation of intracellular Ca2+ levels, decreased mitochondrial transmembrane potential and ATP production. Finally, we showed that MPA-capped CdTe QDs inhibited mitochondrial fission, mitochondrial inner membrane fusion and mitophagy. Taken together, MPA-capped CdTe QDs induced significant mitochondrial dysfunction, which may be caused by imbalanced mitochondrial fission/fusion and mitophagy inhibition. These findings provide insights into the regulatory mechanisms involved in MPA-capped CdTe QDs-induced mitochondrial dysfunction.

Abstract
Multi-target sensing completed with single chemosensor is cost-effective and pretty attractive for the analysis of multiple analytes in single sample. CdTe/CdS QDs show high fluorescence quantum yield as a probe for the sensing purpose, but only single target is often detected. Here we proposed that three kinds of different response mechanisms were realized using CdTe/CdS QDs with the simultaneous sensing of Fe3+, Cr2O72-, and IO3- as model. The specific binding affinity was used to detect Fe3+ with the photo-induced electron transfer (PET) mechanism. CdTe/CdS QDs showed intensive fluorescent response to Cr2O72- owing to the inner filter effect (IFE). IO3- is an oxidant and reacts to surface functional groups of CdTe/CdS QDs with oxidation quenching (OQ) mechanism for the selective detection of IO3-. The three targets recorded with the three mechanisms were obviously clustered even they were tested at different concentrations. Thus, the targets could be differentiated with each other through their different responses of PET, IFE, and OQ. The linear ranges for the selective detection of Fe3+, Cr2O72-, and IO3- were 5.0-100.0, 20.0-140.0 and 1.0-80.0 μM, with the limits of detection as low as 4.1, 9.7, and 0.9 μM, respectively. The proposed methods were satisfactorily applied to accurately detect Fe3+, Cr2O72-, and IO3- in real samples and it was further detected iodate and the total amount of iodine in table salt samples. The proposed multi-target detection strategy with the single fluorescence single from single QDs will stimulate the application of the other matrix with abundant response with enhance sensing efficiency.

Abstract
This work reports the development of highly fluorescent materials for the selective and efficient detection of picric acid explosive in the nanomolar range by fluorescence quenching phenomenon. Poly(vinyl alcohol) grafted polyaniline (PPA) and its nanocomposites with 2-mercaptosuccinic acid (MSA)-capped CdTe quantum dots (PPA-Q) and with MSA-capped CdTe/ZnS core/shell quantum dots (PPA-CSQ) are synthesized in a single step free radical polymerization reaction. The thermal stability and photo stability of the polymer increases in the order of PPA < PPA-Q < PPA-CSQ. The polymers show remarkably high selectivity and efficient sensitivity toward picric acid, and the quenching efficiency for PPA-CSQ reaches up to 99%. The detection limits of PPA, PPA-Q, and PPA-CSQ for picric acid are found to be 23, 1.6, and 0.65 nM, respectively, which are remarkably low. The mechanism operating in the quenching phenomenon is proposed to be a combination of a strong inner filter effect and ground state electrostatic interaction between the polymers and picric acid. A portable and cost-effective electronic device for the visual detection of picric acid by the sensory system is successfully fabricated. The device is further employed for quantitative detection of picric acid in real water samples.

Abstract
Rapid detection of picric acid in real sample is of outmost importance from the perspective of health, safety, and environment. In this study, a very simple and cost-effective detection of picric acid is accomplished by developing a couple of biobased conjugates curcumin-cysteine (CC) and curcumin-tryptophan (CT), which undergo efficient fluorescence turn on toward picric acid in aqueous media. Both the probes experience about 26.5-fold fluorescence enhancements at 70 nM concentration of the analyte. Here, the fluorescence turn on process is governed by the aggregation induced emission, which is induced from the electrostatic interaction between the conjugates with picric acid. The detection limit of CC and CT are about 13.51 and 13.54 nM of picric acid, respectively. Importantly, both the probes exhibit high selectivity and low interference of other analogues toward the detection of picric acid. In addition, the probes are highly photostable, show low response time and are practically applicable for sensing picric acid in real environmental samples, which is the ultimate goal of this work.
