(A) A schematic representation of the formation cysteine capped gold nanoparticles and their interaction at pH 5 9.3. (B) a Meisenheimer complex between modified TNT, possible cross-linking bound to with nanoparticle cysteine.
Vehicle-generated toxic pollutants are composed of gaseous smoke and particulate byproducts accumulated as a black substance at its exhaust. This matter (soot) is utilized for the green synthesis highly stable, non-toxic, environment friendly, carbon quantum dots (CQD). The CQDs synthesized
In the present study, highly luminescent N-doped carbon quantum dots were synthesized by surface passivation of citric acid using Ethylenediamine. As NCQDs characterized different techniques as TEM, DLS zetasizer, UV-Visible spectroscopy and Photoluminescence spectroscopy. N-CQDs found to have approx 6.7 nm diameter spherical shape confirmed from TEM. UV-Vis absorption spectra at wavelength 350 (λmax = nm) their formation in solution. From photoluminescence spectroscopy, it was these emits...
Gold nanoparticles (AuNPs) have indeed been extensively researched in biological and photothermal therapy applications recent years. This study aims to enhance the sensitivity of biosensors for early detection ovarian cancer biomarkers by investigating efficacy DES-mediated surface functionalization AuNPs. Additionally, impact DES on stability dispersion AuNPs SiO2 support is assessed optimize sensor performance. A simple synthesis method efficient amine silicon dioxide (SiO2) incorporate...
Present work reports the green synthesis of highly stable, non-toxic, environmental friendly, fluorescent carbon quantum dots (CQD) via simple synthetic route using waste paper as their precursor. The as-synthesized CQD were post-synthetically modified with (3-Aminopropyl)triethoxysilane (APTES) a nitrogen source for amine functionalized (NCQD) formation. When excited at wavelength λex = 350 nm, maximum emission intensity NCQD was observed λem 450 nm. QDs show blue colored luminescence...
Immunosensors are used to provide simple, quick and effective ways detect analytes for the diagnosis of a number diseases. This work reports on novel optical immunosensor based thyroxine antibody labeled gold nanoparticles (anti-T4/C-AuNPs) sensitive detection (T4) hormone. T4 hormone is reliable diagnostic biomarker present in human blood serum that necessary normal neural development cellular metabolism. The free hormone, major key player total biologically active regulates patient's...
Herein, we demonstrate multiutility zinc-based porous disc particles as a nano-catalyst, for highly sensitive detection, adsorption, and photocatalytic degradation of methylene blue up to ∼95% MB within 70 min ultra-violet irradiation treatment.
The present study has investigated the photoresponse of n-MoS2 QDs/n-MoS2/p-CuO, a hybrid dimensional nanoscale heterostructure fabricated on flexible Ag-coated Kapton substrate. demonstrates significant response toward ultraviolet (UV) (376 nm) to near-infrared (NIR) (1064 wavelengths, even in self-powered mode. type-II formed between and p-CuO layers offers necessary built-in potential for separating transporting photogenerated electron–hole pairs. nanodimensional responsivities 28, 54, 83...
In the present study, Trinitrotoluene (TNT) has been detected by formation of Meisenheimer complex using Fluorescein isothiocyanate (FITC) dye loaded Mesoporous silica particles (MCM-41). FITC mesoporous (MCM-41/FITC) have synthesized (3-Aminopropyl)trimethoxysilane, APTMS (λex = 490 nm and λem 512 nm). TNT forms with amine group on MCM-41 particles. The loading in pores confirmed different advanced characterization techniques. average diameter was found about 130 nm. Pore volume is observed...
Here, a spectroscopic investigation of the interaction between bovine serum albumin protein and thioglycolic acid capped cadmium selenide (CdSe) quantum dots is presented.
