The high‐resolution time diagnostics of ns pulse plasma interacting with micron‐sized droplets under high‐humidity conditions is challenging to achieve with existing experimental methods. This paper employs a global model to study the interaction between plasma and droplets, offering a detailed analysis of the plasma's transition from the gas phase to the liquid phase. It was discovered that in high‐humidity environments, hydrated ions become the predominant ion species. These acidic active substances in PAM droplets are the primary factors in the mist's ability to kill bacteria. The paper further examines how variations in droplet size and discharge voltage influence the PAM's activity.","PeriodicalId":20135,"journal":{"name":"Plasma Processes and Polymers","volume":"57 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141931760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notably, the coating exhibits superhydrophobic characteristics, proven by a water contact angle of approximately 170°, hysteresis angle below 10°, very low tilting angle (<10°), and droplet‐bouncing effect. Importantly, this superhydrophobicity is achieved using OTMSD as fluorine‐free precursor with low reactivity to water.

The experimental results indicated that plasma irradiation may induce plasma‐irradiated HaCaT cells to release soluble factors into the cell culture medium, thereby selectively killing nonirradiated A375 cells.

Herein, we adopt saline and hydrogel as carriers of plasma‐induced reactive species, and link reactive species accumulation, attenuation, storage, and slow‐release to anticancer effects of plasma‐activated media. Results reveal that plasma‐activated hydrogel (PAH) has a sustained anticancer effect and prolongs the storage duration of reactive species, thus causing more intracellular oxidative species accumulation and inducing melanoma cell apoptosis with reactive species continuously released to cell medium. In contrast, plasma‐activated saline has an attenuated anticancer effect with decline in reactive species. Therefore, PAH serves as a useful reactive species carrier and has potential for further anticancer research.","PeriodicalId":20135,"journal":{"name":"Plasma Processes and Polymers","volume":"30 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141769771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For different treatment durations, the optical emission spectra were recorded over time. Most of the emissions are attributed to the N<jats:sub>2</jats:sub> second positive system. The presence of CN is also observed, and its emissions rise with the exposure time of PTFE. This rise is attributed to the density of CN produced. The X‐ray photoelectron spectroscopy surface characterization suggests two etching regimes. This is linked with a change in slope in the intensity evolution of the optical emissions of the CN. At longer times, a fluorinated deposit on the electrode is observed, confirming a different nature of the etched material.","PeriodicalId":20135,"journal":{"name":"Plasma Processes and Polymers","volume":"2 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141569943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
