“…An increase in power [ 28 , 42 ] enhanced the bacterial inactivation, but also results in an increase of plasma temperature [ 42 ]. Additionally, the gas flow influences the plasma temperature [ 75 ]. To avoid thermal damage of the treated tissues the device parameters need to be adjusted [ 76 ].…”

Interest in the application of cold atmospheric plasma (CAP) in the medical field has been increasing. Indications in dentistry are surface modifications and antimicrobial interventions. The antimicrobial effect of CAP is mainly attributed to the generation of reactive oxygen and reactive nitrogen species. The aim of this article is to systematically review the available evidence from in-vitro studies on the antimicrobial effect of CAP on dental pathogens. A database search was performed (PubMed, Embase, Scopus). Data concerning the device parameters, experimental set-ups and microbial cultivation were extracted. The quality of the studies was evaluated using a newly designed assessment tool. 55 studies were included (quality score 31–92%). The reduction factors varied strongly among the publications although clusters could be identified between groups of set pathogen, working gases, and treatment time intervals. A time-dependent increase of the antimicrobial effect was observed throughout the studies. CAP may be a promising alternative for antimicrobial treatment in a clinically feasible application time. The introduced standardized protocol is able to compare the outcome and quality of in-vitro studies. Further studies, including multi-species biofilm models, are needed to specify the application parameters of CAP before CAP should be tested in randomized clinical trials.

“…Because the gas flow rate ranges from 0.2 to 2.4 slm, the plasma jets exist in the laminar mode [ 30 ], where the Reynolds number in the laminar flow mode indicates an increment of R E from 235 to 2819—the type of flow associated with jet velocity. The volume flow is Q = A· v , where A is the sectional area of the ceramic tube hole and v is the argon jet velocity.…”

All Muslim pilgrims must wear Ihram clothes during the Hajj and Umrah seasons, which presents a great challenge regarding how to eliminate the spread of microbes attached to the cotton fabric of Ihram from the surrounding environment. Targeted fashion research of the recent past presents a new industrial treatment, which has led us to study the impact of heat directed from an atmospheric pressure plasma jet (APPJ), coupled with photocatalytic nanomaterials, for the antibacterial treatment of Escherichia coli (E. coli) attached to cotton fabric samples, to improve pollutant remediation. The average rates of heat transfer to the bacterial colonies attached to cotton fabric samples, as a function of the laminar mode, were 230 and 77 mW for dry and wet argon discharges, respectively. The jet temperatures (TJ) and heat transfer (QH) decreased more for wet argon discharge than for dry argon discharge. This is because, due to the wettability by TiO2 photocatalyst concentration dosage increases from 0 to 0.5 g L−1, a proportion of the energy from the APPJ photons is expended in overcoming the bandgap of TiO2 and is used in the creation of electron–hole pairs. In the Weibull deactivation function used for the investigation of the antibacterial treatment of E. coli microbes attached to cotton fabric samples, the deactivation kinetic rate of E. coli increased from 0.0065 to 0.0152 min−1 as the TiO2 precursor concentration increased. This means that the sterilization rate increased despite (TJ) and (QH) decreasing as the wettability by TiO2 photocatalyst increases. This may be due to photocatalytic disinfection and the generation of active substances, in addition to the effect of the incident plume of the non-thermal jet.

“…Pengobatan mastitis subklinis menggunakan teknologi plasma non termal didasari oleh beberapa studi sebelumnya yang membuktikan bahwa plasma memiliki kemampuan menginaktivasi S. aureus dengan perlakuan penyinaran plasma ke cawan petri yang berisi inokulasi S. aureus. Paparan plasma selama 15 menit dapat membuat zona hambat pada cawan petri melebar sebesar 53.37 ± 0.8 mm atau mereduksi S. aureus sebanyak 55% (Al-rawaf et al, 2018). S. aureus merupakan bakteri gram positif yang memiliki yang memiliki struktur peptidoglikan sekitar 74-92% daripada bakteri gram negatif sehingga akan mempengaruhi efektivitas paparan plasma.…”

Subclinical mastitis is the occurrence of inflammation in the parenchymal tissue of mammaryglands due to bacterial contamination that does not show clinical symptoms lead to impacted oneconomic losses. The highest incidence of subclinical mastitis is the presence of Staphylococcusaureus bacteria contamination. Subclinical mastitis in Indonesia is reported to reduce milk productionby up to 53.5%. Pathogenesis of Staphylococcus aureus occurs in the presence of biofilm formation asbacterial immune system to protecting itself from disinfectants and antibiotics. In the last few decades,the development of plasma technology has been widely used in the medical field as cancer therapy,reducing pain, accelerating wound healing and tissue sterilization. There is no study that using theconcept of utilizing Non Termal Plasma in the field of veterinary science, especially in mastitistherapy. Non Termal Plasma is able to decontaminate Staphylococcus aureus through inhibition anddestruction of biofilms. The mechanism of action of Non Termal Plasma in repairing mammary glandtissue is through the destruction of DNA in the Reactive Oxygen Species (ROS) process by increasingthe growth factor TGF-1 which accelerates the process normal cell regeneration. The objective ofthis study is to reviewing the efficacy of plasma non termal as subclinical mastitis theraphy. This studywas conducted through a narrative review approach by collecting international and nationalliterature with interval time of publication within 2010 – 2020.
