Plasma Bionics LLC is a medical device manufacturing company specializing in plasma-based sterilization. Our patented cold plasma generation technology allows rapid sterilization of veterinary instruments at low temperature, with no water or harmful chemicals, and with little power input. As a result, our devices are equally at home on the bench in a veterinary clinic as they are in the vehicle of a mobile veterinarian. Plasma Bionics is committed to providing quality and safe sterilization devices that simplify the sterilization process, reduce operating expenses, and allow sterilization in any environment, providing an efficient point-of-care sterilization solution.
About our Technology
Cold atmospheric plasma, or ionized gas at low temperature and atmospheric pressure, is an emerging decontamination method with a wide variety of potential applications. Cold plasma generated in air produces UV light, charged particles, and reactive oxygen and nitrogen species (RONS)—all of which cause rapid destruction of microorganisms while having limited negative effects on sensitive background substrates. Medical instrument sterilization by cold plasma treatment has been investigated for over two decades but its practical applications for easy use have been limited. Fortunately, cold plasma can be generated in many different ways, and the limitations imposed by the complex apparatuses of previous cold plasma sterilization devices can be overcome.
Plasma Bionics, LLC has developed a plasma-based sterilization device in an innovative and convenient form factor that can be used for sterilizing medical instruments of a wide range of sizes and materials. By utilizing one of the simplest plasma generation methods, surface dielectric barrier discharge (SDBD), plasma is generated with air at room temperature and atmospheric pressure, requiring no additional enclosures or supplied gas flow. SDBD produces plasma as a result of charge accumulation on one side of a dielectric barrier placed between two electrodes. The electric potential accumulates to a point until the air between the electrodes is ionized, forming plasma.
One of the results of the SDBD process is the production of an induced localized airflow. Accordingly, SDBD has been extensively researched and developed for applications in the aerospace industry, in which it is used to induce or modify airflow over the surfaces of aircraft wings. It is a low-power, active flow control technique used to improve the aerodynamic characteristics and propulsion efficiency of aircraft. When used for sterilization applications, the induced airflow allows delivery of RONS, and particularly ozone and nitrogen dioxide (both FDA approved steriliants), to surfaces that are at a distance from SDBD actuators themselves. When applied within an airtight enclosure, RONS accumulate to high levels and contact even the most hard to reach instrument crevices, allowing efficient sterilization with just air and electricity.
