Sustainable strategy of biowaste into graphene-based zinc oxide nanocomposite using green nanotechnology for topical applications.

Metal-based nanoparticles have been extensively researched for their distinctive characteristics. Among them, zinc oxide nanoparticles have numerous applications in the field of biomedicine. The phytoextract of Ixora coccinea flowers was used in the synthesis of ZnO nanoparticles replacing the use of harmful reducing chemicals.

Toxicity optimization of green zinc oxide quantum dots in zebrafish using Box-Behnken design: a novel approach for safer nanoparticle synthesis.

Zinc oxide quantum dots, also known as ZnO QDs, are highly desirable due to their numerous favorable characteristics, such as their beneficial photoluminescence, solubility in water, along with sunlight absorption. They are well-suited for use in biomedical applications, drugs, and bioimaging. However, study on the toxicology of these QDs is needed before they can be used in humans.

Development of bio sheet using nanoparticles and the confederation of protein for casting wound.

This research pioneers a sustainable approach to wound healing by developing a bio sheet for dressings. It ingeniously incorporates healing properties of reduced graphene oxide synthesized via an eco-friendly method, using phytoextracts to eliminate toxic chemicals. Collagen extracted from fish waste and fibrinogen from post-animal waste contribute to the bio sheet's green profile.

Optimization of hematite nanoparticles from natural ore as novel imaging agents: A Green Chemistry approach.

In this research, we propose an environmentally friendly method for producing hematite nanoparticles (H-NPs) from natural hematite ore, focusing on their application as efficient contrast agents in x-ray and computed tomography (CT) imaging for medical purposes. The process involves the reduction of iron oxide within the ore to attain the desired hematite phase, crucial for synthesizing H-NPs. To ensure sustainability, we adopted a Green Chemistry approach, utilizing a combination of carbon soot and limestone for the purification process, thereby achieving eco-conscious production.

Optimization and chemical free fabrication of green synthesized iron nanoparticles as potential MRI contrast agent.

The current research article has investigated the synthesis and characterization of novel iron nanoparticles (INPs) from neem and betel leaves extract combination using response surface methodology-central composite design and coated with chitosan-curcumin (CCINPs) as a biocompatible and contrast agent for magnetic resonance imaging (MRI). The coating of INPs with chitosan and curcumin (CCINPs) was carried out using a simple, easy, chemical-free ultrasonication method and characteristics were confirmed by UV-visible (Vis) spectrophotometer (UV-Vis), Fourier-transform infrared spectroscopy, X-ray diffraction, scanning electron microscope, atomic force microscopy, and vibrating sample magnetometer. The biocompatibility of the particles was ensured by conducting hemolytic and cell viability assays.
