We report a simple one-pot microwave-assisted green-synthesis route for the fabrication of bright red-luminescent graphene quantum dots (GQDs) using ethanolic extracts Mangifera indica (mango) leaves, hence addressing them as mGQDs. The mGQDs were quantum-sized ranging from 2 to 8 nm and exhibited excitation-independent fluorescence emission in near-infrared (NIR) region between 650 750 nm. showed defects their structure highly crystalline nature confirmed by Raman spectroscopy powdered...
Carbon dots (C-dots) are one of the most highlighted carbon-based materials for biological applications such as delivery therapeutic payloads cancer treatment mainly due to their biocompatibility and unique optical properties. In this work, we have explored drug carrying capacity highly fluorescent sorbitol-derived C-dots targeted doxorubicin (DOX). We used folic acid (FA) a navigational molecule its high expression in cells. Before attachment DOX, surfaces were protected with bovine serum...
We report a simple one-pot microwave assisted "green synthesis" of Graphene Quantum Dots (GQDs) using grape seed extract as green therapeutic carbon source. These GQDs readily self-assemble, hereafter referred to "self-assembled" (sGQDs) in the aqueous medium. The sGQDs enter via caveolae and clathrin-mediated endocytosis target themselves into cell nucleus within 6-8 h without additional assistance external capping/targeting agent. tendency self-localize also remains consistent different...
A novel report on microwave assisted synthesis of bright carbon dots (C-dots) using gum arabic (GA) and its use as molecular vehicle to ferry ciprofloxacin hydrochloride, a broad spectrum antibiotic, is reported in the present work. Density gradient centrifugation (DGC) was used separate different types C-dots. After careful analysis fractions obtained after centrifugation, attached synthesize conjugated with C-dots (Cipro @ conjugate). Release found be extremely regulated under...
Carbon dots (C-dots) are novel nanomaterials for biological applications owing to their inherent surface decoration by a variety of functional groups, excellent fluorescent properties and biocompatibility under physiological conditions. Gold nanorods (GNRs) one the most celebrated photothermal therapy as well delivery therapeutic payloads because typical size shape related features. We have synthesized unique blend C-dots GNRs (C-dots@GNRs) controlled release doxorubicin (DOX) ideal Highly...
An Indian fig tree serves as a green factory by providing withered leaves carbon source for graphene quantum dots synthesis. The are multi-functional and have tremendous theranostic biomedical applications.
Abstract Atomically thin (2D) nanoporous membranes are an excellent platform for a broad scope of academic research. Their thickness and intrinsic ion selectivity (demonstrated example in molybdenum disulfide‐MoS 2 ) make them particularly attractive single‐molecule biosensing experiments osmotic energy harvesting membranes. Currently, one the major challenges associated with research progress industrial development 2D nanopore membrane devices is small‐scale thin‐film growth small‐area...
Azadirachta indica as a biological sink for fabrication of gold nanoparticles (GNPs) and its applications in efficient delivery doxorubicin (DOX) are presented here. Sucrose density gradient centrifugation was used to isolate the spherical GNPs <50 nm from mixture (containing both non-spherical) synthesized using leaves A. at inherent pH (6.14). The stability due capping agents scrutinised by measuring flocculation parameter which found be range 0-0.65. On surface these capped GNPs, attached...
Due to the abundance of silica and carbon in rice (Oryza sativa) husk (RH), we exploited it for synthesis a mesoporous oxide micro-particles (meso-SiO2)/C-dot complex biological imaging using novel hot injection method commonly used semiconductor quantum dots. Carbon dots (C-dots) with high degree green fluorescence were observed under UV-light they found be embedded significant extent meso-SiO2 as confirmed by transmission electron microscopy (TEM) energy dispersive spectroscopy (EDS). The...
The use of phenylalanine derived non-toxic carbon dots (C-dots) as a vehicle for the delivery widely used anti-psychotic drug haloperidol (HaLO) is described in present research work. C-dots were found to have remarkable optical properties and exhibit bright green fluorescence under UV light (λex = 365 nm).

Abstract Nanopores in two-dimensional (2D) membranes hold immense potential single-molecule sensing, osmotic power generation, and information storage. Recent advances 2D nanopores, especially on single-layer MoS 2 , focus the scalable growth manufacturing of nanopore devices. However, there still remains a bottleneck controlling stability atomically thin membranes. Here, we evaluate major factors responsible for instability monolayer nanopores. We identify chemical oxidation delamination...
Among numerous thin film synthesis methods, metalorganic chemical vapor deposition performed in a showerhead reactor is the most promising one for broad use scalable and commercially adaptable two-dimensional material processes. Adapting efficient monolayer growth methodologies from tube-furnace systems to vertical-showerhead geometries allows us overcome intrinsic process limitations improve overall yield quality. Here, we demonstrate large-area, molybdenum disulphide by combining gas-phase...
