Green Synthesis of Luminescent Carbon Dots from Ficus benghalensis Aerial Roots for Bioimaging.

In this work, carbon quantum dots (CQDs) were prepared using a one-step hydrothermal green synthesis method from a low-cost and eco-friendly renewable biomass, specifically the Ficus benghalensis aerial roots (FB-AR). For the past two decades, CQDs have been noted for their tunable emission spectrum, quantum yield, biocompatibility, photostability, and unique optoelectronic properties such as photoluminescence (PL), and fluorescence. The synthesized Ficus benghalensis carbon quantum dots (FB-CQDs) were characterized for their physical, structural, and chemical properties using XRD, Raman, HRTEM, XPS, FTIR, TG-DTG, UV-visible, and photoluminance analysis.

NiCoO/TiNbC (double MXene) nanohybrid-based non-enzymatic electrochemical biosensor for the detection of glucose in sweat.

The non-enzymatic electrochemical sensors are attractive due to their high sensitivity, quick detection, low cost, and simple construction. Hence, in this work, a non-enzymatic biosensor was constructed with NiCoO nanoparticles (~ 82 nm) decorated over TiNbC nanosheets by an in-situ method. The crystal structure, phase purity, morphology and elemental composition of the synthesized NiCoO/TiNbC nanohybrid was investigated using XRD, Raman and FESEM analysis.

Polymer-mediated electrospun nanofibrous mats on supramolecular assembly of nortriptyline in the β-cyclodextrin medium for antibacterial study.

With the thought and strong hope of uniqueness and challenging characteristic highlights and importance of nanofibrous mats (NFMs) along with cyclodextrins (CDs) that having a significant opportunity, chances and handling a vital role in hostile to bacterial activities. For the most part, CDs are utilized to upgrade the antibacterial activity through the improvement of solubility, stability, and etc., to any molecule which can bring inside the CDs cavity the formation of inclusion complexes.

Biologically reduced graphene oxide as a green and easily available photocatalyst for degradation of organic dyes.

The disposal of untreated textile industrial wastewater having unmanageable pollutants is a global issue. Eco-friendly remediation technology is needed for the removal of environmental contaminants. In this study, a simple hydrothermal method is adapted to synthesis reduced graphene oxide (PErGO) using Phyllanthus emblica fruits extract and used as a photocatalyst for the degradation of synthetic toxic dyes.

Mesoporous Carbon/α-FeO Nanoleaf Composites for Disposable Nitrite Sensors and Energy Storage Applications.

In this work, we report a novel hydrothermal synthesis of α-FeO nanoleaf-incorporated mesoporous carbon-chitosan (α-FeO@MPC-chit) as a versatile disposable sensor for selective electrochemical detection of nitrite and for supercapacitor applications. The newly synthesized α-FeO@MPC-chit nanocomposite was characterized by scanning electron microscopy, X-ray diffraction, Fourier transform-infrared spectroscopy, UV, and Raman spectroscopy. The extensive physicochemical characterization reveals the strong immobilization of α-FeO nanoleaves within the MPC-chit composite.
