Nanosized particles, with a size of less than 100 nm, have a wide variety of applications in various fields of nanotechnology and biotechnology, especially in the pharmaceutical industry. Metal nanoparticles [MNPs] have been synthesized by different chemical and physical procedures. Still, the biological approach or green synthesis [phytosynthesis] is considered as a preferred method due to eco-friendliness, nontoxicity, and cost-effective production. Various plants and plant extracts have been used for the green synthesis of MNPs, including biofabrication of noble metals, metal oxides, and bimetallic combinations. Biomolecules and metabolites present in plant extracts cause the reduction of metal ions into nanosized particles by one-step preparation methods. MNPs have remarkable attractiveness in biomedical applications for their use as potential antioxidant, anticancer and antibacterial agents. The present review offers a comprehensive aspect of MNPs production via top-to-bottom and bottom-to-top approach with considerable emphasis on green technology and their possible biomedical applications. The critical parameters governing the MNPs formation by plant-based synthesis are also highlighted in this review.

Fluid mixing in lab-on-a-chip devices at laminar flow conditions result in a low mixing index. The reason is dominant diffusion over the convection process. The mixing index can be improved by certain changes in the micromixer structural design like introducing obstacles in the path of fluid flow. These obstacles will make dominant the advection process over the diffusion process. The main contribution of this work is based on proposing the novel hybrid type micromixer design for enhancing the mixing quality. Three non-aligned M-type and non-aligned M-type with obstacles passive type micromixers are analyzed by COMSOL5.5. These designs are hybrid types because different structural changes are combined in a single design for mixing improvement. First of all the straight non-aligned inlets, M-type passive micromixer (SMTM) is analyzed. It is observed that mixing performance is improved because of M-shaped mixing units and non-aligned inlets. This improvement is deemed to be not enough so different shaped obstacles are introduced in the micromixer design. These designs based on obstacles are named horizontal rectangular M-type micromixer, square M-type micromixer, and vertical rectangular M-type micromixer. The mixing index for SMTM, square M-type micromixer, horizontal rectangular M-type micromixer, and vertical rectangular M-type micromixer at Reynolds number Re = 60 is respectively given by 71.1%, 83.21%, 84.45%, and 89.99%. The mixing index of vertical rectangular M-type micromixer was 59.34% − 87.65% for Re = 0.5–100. Vertical rectangular M-type micromixer is concluded with the better-mixing capability design among the proposed ones. Based on these simulation results, the vertical rectangular M-type micromixer design can be utilized for mixing purposes in biomedical applications like nanoparticle synthesis and biomedical sample preparation for drug delivery.

Recent advances in the field of nanotechnology such as nanoencapsulation offer new biomedical applications, potentially increasing the scope and efficacy of therapeutic drug delivery. In addition, the discovery and development of novel biocompatible polymers increases the versatility of these encapsulating nanostructures, enabling chemical properties of the cargo and vehicle to be adapted to specific physiological requirements. Here, we evaluate the capacity of various polymeric nanostructures to encapsulate various antibiotics of different classes, with differing chemical structure. Polymers were sourced from two separate derivatives of poly(methyl vinyl ether-alt-maleic anhydride) (PMVE/MA): an acid (PMVE/MA-Ac) and a monoethyl ester (PMVE/MA-Es). Nanoencapsulation of antibiotics was attempted through electrospinning, and nanoparticle synthesis through solvent displacement, for both polymers. Solvent incompatibilities prevented the nanoencapsulation of amikacin, neomycin and ciprofloxacin in PMVE/MA-Es nanofibers. However, all compounds were successfully loaded into PMVE/MA-Es nanoparticles. Encapsulation efficiencies in nanofibers reached approximately 100% in all compatible systems; however, efficiencies varied substantially in nanoparticles systems, depending on the tested compound (14%–69%). Finally, it was confirmed that both these encapsulation processes did not alter the antimicrobial activity of any tested antibiotic against Staphylococcus aureus and Escherichia coli, supporting the viability of these approaches for nanoscale delivery of antibiotics.

Abstract Background Scientists created a new area known as "green nanotechnology" by combining the concept of sustainability with nanotechnology. Its goal is to eliminate the use of chemicals in nanoparticle manufacturing by replacing them with plant-based materials. Green synthesis is promoted as the best alternative to the traditional method of nanoparticle synthesis in this new domain. Plants that constitute a major portion of our biodiversity are embraced with inherent potentiality to be transformed as miracle medicine due to its phytochemicals. These phytochemicals efficiently replace the classical wet chemical ingredients involved in nanoparticle synthesis by upgrading to greener method for its synthesis. By incorporating plant-based sources as the chief ingredient of nanoparticle synthesis, we are able to reduce the hazards of greenhouse gas emissions and enlighten the insights of our scientific community with nanotechnology for green innovation. Hence, this review simultaneously aims at promoting plant extracts as the most efficient as well as renewable recipe for green synthesis of silver nanoparticles and preparing earth for a greener tomorrow. Methodology Scientific articles and publications were selected from reputed journals and sorted out with pertinent keywords of this review. Electronic sources like Google Scholar, PubMed, Research Gate, Science Direct, Wiley Online Library, Web of Science and Scopus were searched for potential articles and recent breakthroughs published in the area of silver nanoparticle synthesis via green chemistry and biological methods using plant extracts. Scientific names of medicinal plants were checked using botanical databases like Plant List and International Plant Names Index. Conclusion This review pinpoints on empowering better life on earth by protecting it from hazardous effects of conventional nanotechnological production through replacing the former with sustainable green synthesis approach. Ergo, it outlines that by incorporating plant-based sources as the chief ingredient of nanoparticle synthesis, we are able to reduce the hazards of greenhouse gas emissions in turn by slowing down increasing climate change disasters globally and enlighten the insights of our scientific community with nanotechnology for green innovation.
