The New Advance on Disinfectant of Virus and Microorganisms 2.0

Dear Colleagues,

This Special Issue is a continuation of our 2022 Special Issue "The New Advance on Disinfectant of Virus and Microorganisms".

Nanomaterials have the ability to prevent viral contamination by air and contact with contaminated surfaces and have the ability to sterilize protective equipment especially in hospital settings. Creating self-disinfeting surfaces is another strategy to prevent the spread of COVID-19.

Besides, non-thermal plasam application is a novel way in medical treatments. Development of coagulation methods using non-thermal plasma is critical for surgical application. Aragon plasma coagulation-assisted tonsillectomy reduced the oprtation time.  Reactive Oxygen Species are engages in the wound healing process during this oparation. More use of photocatalysis and UV-C is expected for the protective equipment of hospital settings besides mechanical ventilation. There are several products made of nanocomposites that have antimicrobial activities and used in the disinfection of surfaces. CAC-717 is a new disinfectant consisting of calcium bicarbonate mesoscopic crystals that are a compound containing mesostructured nanoparticles and are involved in inactivating enveloping and non-enveloping viruses. Graphene in face masks can also sterilize SARS-CoV-2 and allow them to be reused. This coating is also suitable for use on surface in public places. In Kampo medicine there are so many materials working for antiviral effects for SARS-CoV-2.

The unpredictable and unknown nature of COVID-19 and the similarity of the specific properties this disease and the physicochemical properties of nanosystems will lead to the discussion of solutions based on new technologies.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Microorganisms is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
