The miniaturization of reaction processes by microreactors offers many significant advantages over the use larger, conventional reactors. Microreactors' interior structures exhibit comparatively higher surface area-to-volume ratios, which reduce reactant diffusion distances, enable faster and more efficient heat mass transfer, better control process conditions. These can be exploited to significantly enhance performance advanced oxidation (AOPs) commonly used for removal water pollutants. This comprehensive review rapidly emerging area environmental microfluidics describes recent advances in development application AOPs wastewater treatment. Consideration is given hydrodynamic properties, construction materials, fabrication techniques, designs, features, upscaling AOPs. various AOP types, including photocatalytic, electrochemical, Fenton, ozonation, plasma-phase processes, showcases how microfluidic technology enhances improves treatment efficiency, decreases consumption energy chemicals. Despite advancements microreactor technology, organic pollutant degradation mechanisms that operate during microscale remain poorly understood. Moreover, limited throughput capacity systems restrains their industrial-scale applicability. Since large microreactor-inspired are needed meet high-throughput requirements sector, scale-up strategies recommendations suggested as priority research opportunities. While microstructured reactor remains an early stage development, this work valuable insight future purposes.

Abstract One of the major challenges on way to low‐cost, simple, and effective cancer treatments is lack smart anticancer drug delivery materials with requisite site‐specific microenvironment‐responsive properties. This work reports development plasma‐engineered nanocarriers (SDNCs) containing chitosan nitrogen‐doped graphene quantum dots (NGQDs) for in a pH‐responsive manner. Through customized microplasma processing, highly cross‐linked SDNC only 4.5% NGQD ratio can exhibit enhanced toughness up threefold higher than control group, avoiding commonly used high temperatures toxic chemical cross‐linking agents. The SDNCs demonstrate improved loading capability doxorubicin (DOX) via π–π interactions stable solid‐state photoluminescence monitor DOX release through Förster resonance energy transfer (FRET) mechanism.

Microbial biofilms cause contaminations in different environmental settings, including pipelines, filters, membranes, food and processing infrastructure. They ultimately pose a major risk to human health necessitate costly cleaning repair. Cold plasma, partially ionised gas, plasma-activated water (PAW) exhibit powerful disinfectant activity. However, the optimal generating conditions, such as choice of gas used produce PAW, remain unclear. Here, range PAWs were generated from argon, nitrogen, air, oxygen plasma bubble spark discharge (BSD) reactor capable directly treating Escherichia coli (ATCC 25922) situ. We measured reactive nitrogen species (RONS) (H2O2, NO3-, NO2-) PAW excited via optical emission spectroscopy (OES). using (PAW-O2) was most effective completely removed E. on stainless steel surfaces.
