Quantitative detection of cancer biomarkers with higher accuracy and sensitivity provides an effective platform for screening, monitoring, early diagnosis, disease surveillance. The present work demonstrates the fabrication application fluorescent turn-on biosensor ultrasensitive small cell lung biomarker utilizing biofunctionalized graphene quantum dots as energy donor gold nanoparticles (AuNPs) acceptor. One-pot bottom-up hydrothermal route have been employed synthesis in situ...
Graphene quantum dots (GQDs) are one of the most promising luminescent carbon derived nanomaterials decorated with multiple useful functional groups and remarkable optoelectronic properties. Heteroatom doping hexagonal sheet GQDs is an effective strategy to tailor their properties meet desired application. In this work, sulfur doped (S-GQDs) were synthesized by simply pyrolyzing citric acid (CA) as a source 3-Mercaptopropionic dopant. The optimal reaction conditions (ratio dopant source,...
In this work, a new nanocomposite (Ag@S-GQDs) have been synthesized using one-step facile synthesis process and their antibacterial as well cytotoxicity properties were investigated systematically.
This review summarizes the recent progress in synthetic, functional, structural and property control strategies of GQDs their current potential applications biomedical optoelectronic domain.
Pictorial representation of various topics discussed in the review: GQDs synthesis strategies, properties, their regulation through heteroatom doping/surface functionalization, and (bio)analytical sensors (optical, ECL, electrochemical).
Abstract In this work, we report, the synthesis of Boron and Sulfur co-doped graphene quantum dots (BS-GQDs) its applicability as a label-free fluorescence sensing probe for highly sensitive selective detection dopamine (DA). Upon addition DA, intensity BS-GQDs were effectively quenched over wide concentration range DA (0–340 μM) with an ultra-low limit 3.6 μM. The quenching mechanism involved photoinduced electron transfer process from to dopamine-quinone, produced by oxidization under...
In recent decades, nature-inspired optimization methods have played a critical role in helping industrial plant designers to find superior solutions for process parameters. According the literature, such are simple, quick, and indispensable saving time, money, energy. this regard, Modified Whale Optimization Algorithm (MWOA) hybridized with Artificial Neural Networks (ANN) has been employed Reverse Osmosis (RO) desalination performance estimate permeate flux (0.118‒2.656 L/h m2). The plant's...
In the current work, renewable resourced toughened epoxy blend has been developed using epoxidized linseed oil (ELO) and bio‐based crosslinker. Epoxidation of was confirmed through FTIR 1 H NMR spectra. The ELO bio‐resin blended at different compositions (10, 20, 30 phr) with a petroleum‐based (DGEBA) as reactive diluent to reduce viscosity for better processibility cured cardanol‐derived phenalkamine overcome brittleness. flow behavior neat modified bio‐epoxy resin systems analyzed by Cross...
Bio‐based epoxy resins were synthesized from nonedible resources like linseed oil and castor oil. Both the oils epoxidized through in situ method characterized via Fourier transform infrared 1 H‐NMR. These crosslinked with citric acid without using any catalyst their properties compared diglycidyl ether of bisphenol A‐epoxy. The tensile strength modulus (ELO) found to be more than those (ECO)‐based network. However, elongation at break ECO was significantly higher that both ELO epoxy, which...
Abstract The development of an analytical probe to monitor highly mutagenic picric acid (PA) carries enormous significance for the environment and health. A novel, simple rapid fluorescence assay using sulfur‐doped graphene quantum dots (SGQDs) was designed sensitive selective detection PA.
