A direct current atmospheric pressure cold plasma microjet (PMJ) was used to produce activated water (PAW) in two generation modes above (PAW‐A) and beneath (PAW‐B) the surface. The physicochemical characteristics biological effects of them were measured respectively. Results showed that PAW‐B exhibited stronger disinfection efficiency than PAW‐A, which associated with ORP conductivity, but not pH value, temperature, H 2 O , NO 3 − or . Furthermore, cell membrane integrity potential S....
Tactile perception includes the direct response of tactile corpuscles to environmental stimuli and psychological parameters associated with brain recognition. To date, several artificial haptic-based sensing techniques can accurately measure physical stimuli. However, quantifying achieve texture roughness identification remains challenging. Here, we developed a smart finger surpassed human perception, which enabled accurate material type through integration triboelectric machine learning. In...
Abstract Electrical interactions between bacteria and the environment are delicate essential. In this study, an external electrical current is applied to capacitive titania nanotubes doped with carbon (TNT-C) evaluate effects on killing underlying mechanism investigated. When TNT-C charged, post-charging antibacterial proportional capacitance observed. This capacitance-based system works well both direct alternating (DC, AC) higher discharging capacity in positive DC (DC+) group leads better...
The endogenous electric field (EF) generated by transepithelial potential difference plays a decisive role in wound reepithelialization. For patients with large or chronic wounds, negative-pressure therapy (NPWT) is the most effective clinical method inflammation control continuously removing necrotic tissues infected substances, thus creating proproliferative microenvironment beneficial for However, continuous drainage causes electrolyte loss and weakens EF, which turn hinders Here, an...
Ar/O2 (2%) cold plasma microjet was used to create plasma-activated water (PAW). The disinfection efficacy of PAW against Staphylococcus aureus showed that can effectively disinfect bacteria. Optical emission spectra and oxidation reduction potential results demonstrated the inactivation is attributed oxidative stress induced by reactive oxygen species in PAW. Moreover, X-ray photoelectron spectroscopy, atomic absorption spectrometry, transmission electron microscopy suggested chemical state...

Abstract In this work, a nanogenerator‐controlled drug delivery system (DDS) for use in cancer therapy is successfully established. A new magnet triboelectric nanogenerator (MTENG) fabricated that can guarantee the contact and detach cycle between two friction layers effectively increase TENG output, up to 70 V after implantation. Using special structural design, without commonly used spacer, contacting‐mode MTENG ensure high consistent electricity output encapsulation Doxorubicin‐(DOX‐)...
Magnesium-based materials are preferred in temporary orthopedic implants because of their biodegradability, mechanical properties, and intrinsic antibacterial properties.
