Nanomaterial-microorganism hybrid systems (NMHSs), integrating semiconductor nanomaterials with microorganisms, present a promising platform for broadband solar energy harvesting, high-efficiency carbon reduction, and sustainable chemical production. While studies underscore its potential in diverse solar-to-chemical conversions, prevailing NMHSs grapple suboptimal conversion efficiency. Such limitations stem predominantly from an insufficient systematic exploration of the mechanisms dictating flow. This review provides overview notable advancements this nascent field, particular focus on discussion three pivotal steps flow: capture, cross-membrane transport, into chemicals. key challenges faced each stage are independently identified discussed, viable solutions correspondingly postulated. In view interplay affecting overall efficiency conversion, subsequent discussions thus take integrative viewpoint to comprehend, analyze improve flow current different configurations, highlighting contemporary techniques that can be employed investigate various aspects within NMHSs. Finally, concluding section summarizes opportunities future research, providing roadmap continued development optimization

Abstract Background Bacterial biosynthesis of fluorescent nanoparticles or quantum dots (QDs) has emerged as a unique mechanism for heavy metal tolerance. However, the physiological pathways governing removal QDs from bacterial cells remains elusive. This study investigates role minicells, previously identified means eliminating damaged proteins and enhancing resistance to stress. Building on our prior work, which unveiled formation minicells during cadmium in Escherichia coli , we hypothesize that serve accumulation detoxification cells. Results Intracellular CdS was performed E. mutants Δ minC minCDE known their minicell-producing capabilities. Fluorescence microscopy analysis demonstrated generated exhibited fluorescence emission, indicative QD loading. Transmission electron (TEM) confirmed presence while energy dispersive spectroscopy (EDS) revealed coexistence sulfur. Cadmium quantification through flame atomic absorption spectrometry (FAAS) accumulated higher content compared rod Moreover, intensity suggested greater quantity nanoparticles, underscoring efficacy removal. Biosynthesis dynamics strains indicated biosynthesized maintained high even prolonged times, suggesting continuous clearance minicells. Conclusions These findings support model wherein utilizes highlighting harmful elements maintaining cellular fitness. Additionally, this system presents an opportunity generating minicell-coated with enhanced biocompatibility diverse applications. Graphical

Researchers have shown significant interest in the creation of sustainable green techniques for synthesising metal oxide nanomaterials past few years. Plant-mediated production is considered an affordable and feasible alternative to traditional physical chemical approaches. This study presents a straightforward approach environmentally friendly copper nanoparticles (CuO NPs) by solution combustion technique utilising Jasminum sambac Flower Extract. The CuO NPs produced during biosynthesis were analysed using UV-Vis, XRD, FT-IR, SEM, TEM, HPLC, BET EDX techniques. SEM pictures reveal that fragments possess sponge-like structure characterised substantial surface area. An investigation into photocatalytic activity shows they are effective as catalyst breakdown methylene blue (MB) when exposed UV solar radiation. Furthermore, demonstrated pH dependence MB. According study, best starting concentration dye breaking down things completely 2.5 parts per million (ppm), which results remarkable 79 % disintegration rate. findings indicate ability effectively treat water decomposing contaminants such blue, providing method treating wastewater.

Metal-enzyme cascade catalysis effectively combines the broad reactivity of chemical with high selectivity biocatalysis, improving reaction efficiency and simplifying process flow through multiple sequential reactions in same system. The introduction exogenous palladium nanoparticles (Pd NPs) into Escherichia coli (E. coli) cells can significantly broaden range catalytic facilitated by biological enzymes. Additionally, targeted cytoplasmic synthesis Pd NPs enhances their utilization intracellular while also eliminating need for separating purifying metals However, current methods largely enable periplasmic space outer membrane. Moreover, hydrogen sources commonly used these methods─such as (H2) sodium borohydride (NaBH4)─carry safety risks. In this study, mechanism on side its were deeply investigated using a mild source, formate, combination genetic engineering preparation conditions. And constructed functional cell (Pd@E. could catalyze benzaldehyde hydrogenation, conversion rate 41.41% benzyl alcohol yield 17.68%, demonstrating considerable loading stability. This study provides reference constructing systems metal-enzyme cascades. Thus, it bolster development opportunities areas non-natural products drug provide ideas addressing drawbacks existing biosynthetic technologies.
