A method of forming metal nanoparticles includes applying a substance to an area of interest, applying cold plasma to the area of interest, and synthesizing nanoparticles from the substance using the cold plasma in the area of interest, wherein the substance is a solution that contains metal ions, and the nanoparticles synthesized are metallic in nature.

Disinfection devices are provided which include an enclosure comprising an interior cavity, a closable loading port for providing access to the interior cavity, a cold plasma generator, a fan, a nebulizer and optionally a heating element to heat the interior cavity. In some cases, the cold plasma generator, the fan, and the nebulizer are arranged in the disinfection device such that plasma species generated by the cold plasma generator are routed to an area to which droplets formed by the nebulizer are discharged and the interior cavity is exposed to a mixture of the droplets and the plasma species. In some additional or alternative cases, the disinfection device includes an electronic control system comprising a processor and a storage medium comprising program instructions executable by the processor for terminating operation of the cold plasma generator after a set time period subsequent to terminating operation of the nebulizer.

Systems and methods are disclosed for sterile delivery of prostheses that protect refined and/or conditioned surface properties and thereby reduce aging of surface properties in prostheses. An example of the system includes a partially custom-shaped holder that also serves as an insertion tool that holds a customized dental prosthesis in a pre-defined position inside a titanium container that is hermetically sealed. Container materials serve as a getter or catalyst with respect to the osseoconductive surface. An example of the method includes laser welding to hermetically seal a metal container as packaging for a prosthesis with a metal foil, and the sterilization of the packaged and sealed prosthesis with dry heat.
