Facile Synthesis of Multifunctional Carbon Dots Derived from Camel Milk for Mn⁷⁺ Sensing and Antiamyloid and Anticancer Activities

ACS Omega, Journal Year: 2023, Volume and Issue: 8(39), P. 36521 - 36533

Published: Sept. 20, 2023

Carbon dots (CDs) are promising biocompatible fluorescent nanoparticles mainly used in bioimaging, drug delivery, sensing, therapeutics, and various other applications. The utilization of natural sources green synthetic approaches is resulting highly nontoxic nanoparticles. Herein, we report an unprecedented facile synthesis luminescent carbon derived from camel milk (CM) for sensing manganese (Mn7+) ions identifying the anticancer potential antiamyloid activity against α-synuclein amyloids. α-Synuclein amyloid formation due to protein misfolding (genetic environmental factors) has gained significant attention its association with Parkinson's disease synucleinopathies. as-synthesized CM-CDs possess average hydrodynamic diameter ranging 3 15 nm also exhibit strong photoluminescence (PL) emission blue region. good water dispersibility, stable fluorescence under different physical states, outstanding photostability. Moreover, validated as efficient sensor detection Mn7+ DI metal ion-polluted tap water. In addition, have demonstrated a very quantum yield (QY) 24.6% limit (LOD) 0.58 μM no incubation time. Consequently, exceptional properties make them suitable diverse array biomedical

Evaluation of phthalic acid tri-ethylene diamine (TED) and folic acid-based carbon quantum dots for the detection of heavy metals in water resources using fibre-optic instrumentation

Environmental Technology, Journal Year: 2023, Volume and Issue: 45(18), P. 3533 - 3543

Published: May 30, 2023

ABSTRACTHeavy metal pollution and toxicity from water resources have remained a great concern for the entire population. This research demonstrates capability of carbon quantum dots (CQDs) fluorescence-based heavy detection in different using fibre-optic spectrometer device. Two types CQDs phthalic acid triethylenediamine (PT CQDs) Folic (FCQDs) were synthesized microwave irradiation hydrothermal method, respectively. characterized several techniques such as TEM, EDX, XPS FTIR. PTCQD FCQDs both tested sensing reservoirs like household river water. The results indicate that able to detect all six ions (Pb2+, Co2+, Mn3+, Hg2+, Ni2+, Cr3+) study range 0–100 µM. It was found show three-fold higher sensitivity greater resolution than PTCQDs metals samples. CQDs' shows they can achieve limit 0.15–3 µM along with 100% accuracy terms recovery minimal error, these tremendous potential be used sensor even complex matrices. more compared future tool better less response time.KEYWORDS: Carbon dotsheavy pollutionfluorescencewater resourcesfibre-optic Disclosure statementNo conflict interest reported by author(s).Additional informationFundingTV acknowledges Ministry Education-Prime Minister Research Fellowship (PMRF) [grant number 2101309] DST-INSPIRE financial support, AJ MG acknowledge Department Biotechnology (DBT) Project BT/PR24652/NER/795/2017], DST FIST No. SR/FST/LS-I/2020/62.
