چکیده
Foodborne illness outbreaks have significantly impacted public health. The contact antibacterial nanomaterials may potential migration of and thus bring safety concerns. In this work, we develop photo-triggered nano-generators for on-demand release essential oil vapor to achieve a non-contact strategy between target bacteria. This nano-generator (Fe3O4@[email protected]/carvacrol, FPZC) is composed photothermal Fe3O4@PDA-COOH cores in zeolitic imidazolate framework-67 (ZIF-67) shell with loaded carvacrol. Briefly, these magnetic transfer immobilization, photo-thermal conversion, controlled carvacrol capacities. Under laser irradiation at wavelength 808 nm 60 s, 80 mg FPZC can rapidly 171.0 μg/L the air completely inactivate Staphylococcus aureus Escherichia coli initial amount 5 log CFU. Photo-triggered exhibit flexible property, high killing rate (100%), good recyclability (5 cycles). Compared conventional strategy, cannot concerns nanomaterial into sterilized material, therefore provides promise practical applications especially food-related sterilization.

Photo- and thermoresponsive polymersomes for triggered release.
Microfluidics: Thermo- and photoresponsive polymersomes are assembled using capillary microfluidic devices. Encapsulants can be selectively released from the thermoresponsive polymersomes if they are incubated at and above temperatures of 40 °C, whereas the photoresponsive polymersomes selectively release encapsulants if illuminated with laser light (see picture; NP = nanoparticle).

Metal and metal-oxide nanoparticles (NPs) are used in numerous applications and have high likelihood of entering engineered and natural environmental systems. Careful assessment of the interaction of these NPs with bacteria, particularly biofilm bacteria, is necessary. This perspective discusses mechanisms of NP interaction with bacteria and identifies challenges in understanding NP-biofilm int...

Background and aims: Clean air is one of the most important components of health and sustainable development. Every person breathes about 10 kg of air per day and if it contains pollutants, it will have a serious impact on their health. Indoor air quality (IAQ) is one of the major health issues that have been addressed in recent years with changes in lifestyle patterns. Usually, due to the incr...
