I did find a source confirming the feasibility based apparently on extensive implementation.
It occurred upon my searching for microjets, where I came upon this reference: Tian, Y.; Sun, P.; Wu, H.; Bai, N.; Wang, R.; Zhu, W.; Zhang, J.; Liu, F. ‘Inactivation of Staphylococcus aureus and Enterococcus faecalis by a direct-current, cold atmospheric-pressure air plasma microjet’ in J. Biomed. Res. 2010, 24, 264–269.
It is cited in this 2019 work, published in International Journal of Molecular Science, 2019, 20, 5216; doi: 10.3390/ijms20205216 .
To quote pertinent passages from the work: 'Different types of plasma can be used in various biological fields, including disinfection/sterilization' including a type referred to as non-thermal plasma. Here is a pertinent extract from Table I:
Glow discharge, Corona discharge, atmospheric pressure plasma jet (APPJ), dielectric barrier discharge (DBD), micro-hollow cathode discharge (MHCD), Plasma needle, (MHCD), Plasma needle, Low-pressure plasma etc.
Ozonizer, Plasma medicine, Volatile organic compound (VOC) treatment, Plasma modifications (coating, etching, activation, cleaning, nitration, etc.),
The work notes the following:
The potential of plasma technology in medical and dental applications is extremely broad. As well as disinfection/sterilization of medical and dental devices, the technology could be used to treat beds, desks, and floors . Plasma technology may also have therapeutic potential [91–93]. Therapeutic uses include the treatment of skin diseases , blood coagulation  as well as dental treatment  and applications in dermatology such as chronic wound healing .
As to an explanation of underlying mechanics to quote:
Plasma treatment is an especially promising method because the mechanism of bactericidal action is unlikely to differ between multidrug-resistant and normal bacteria. The main mechanisms of bactericidal action in plasma are thought to involve exposure to reactive chemical species for which multidrug-resistant bacteria are unlikely to be resistant .
Reactive chemical species seem to be the principal inactivation factor in most cases, although this may vary depending on the method of plasma generation and whether the sample is exposed to direct or indirect plasma treatment.
Where the reference  above, in its extract cites:
Reactive chemical products (hydrogen peroxide-like chemicals), ultraviolet light (UV-A) and slight temperature elevations were observed during the operation of the gas plasma device.
which is also a confirmation of my cited reactive oxygen species (ROS) chemistry where, in the proposed case of wound treatment, for example, we have iron-rich blood with in situ apparently created H2O2, likely forming powerful disinfecting ROSs. Another example, is the more classic Fenton remediation chemistry, removing organic VOCs, with the likes, of yes, perhaps FeCl2.
