In recent years, green synthesis methods for producing nanomaterials have gained significant interest due to their environmentally friendly nature and wide‐ranging applications. The present study addresses a novel of graphene quantum dots (GQDs) using leaves Withania somnifera. size, morphology, stability the green‐synthesized GQDs were characterized TEM, UV‐Visible spectroscopy, Fluorescence spectrophotometer, XRD, DLS. bio‐functional properties investigated, with focus on antidiabetic antioxidant capabilities. Their activity was assessed by examining ability inhibit α‐amylase α‐glucosidase enzymes, which play crucial role in glucose metabolism. Additionally, evaluated DPPH● scavenging assays, highlighting effectiveness neutralizing free radicals. findings revealed that synthesized outperformed original leaf extract both enzyme inhibition. exhibited higher IC 50 values inhibiting DPPH (78.508 ± 5.71), (161.909 6.188), (133.345 7.328) compared GQDs, showed lower 72.74 5.9, 137.966 6.95, 122.084 5.478, respectively. indicate somnifera derived hold potential medical applications, warranting further investigation into therapeutic efficacy.

This publication summarises the current state of knowledge and technology on possibilities limitations using mineral synthetic fillers in field 3D printing thermoplastics. FDM can be perceived as a miniaturised variation conventional extrusion processing (a microextrusion process). However, scaling process down has an undoubtful drawback significantly reducing extrudate diameter (often by factor ≈20–30). Therefore, results produced under cannot simply translated to processes run with application technology. With that mind, discussing latest findings composite materials preparation was necessary.

Abstract In the antimicrobial resistance era, carbon‐based nanomaterials (CBNs) such as fullerenes, carbon dots, graphene, and their derivatives are promising therapeutic tools in combating viral diseases. This review shows that these materials have broad‐spectrum antiviral activity against 33 viruses belonging to different Baltimore groups. CBNs also exhibit bacteria fungi possess a low risk of selecting for resistance, since primary mode action involves physically damaging microbes. offer additional properties, including enhanced effectiveness under diverse types irradiation facilitating immune responses. Their potential agents is still its infancy future research should focus on toxicity, mechanisms, pharmacokinetics, bioavailability. They preventing transmission diseases use face masks, shields, hospital airport surfaces, elevators, among others. It anticipated will play an increasingly significant role fight infectious
