What is considered the newest low-temperature sterilization process?

The newest low-temperature sterilization process is ozone. Ozone sterilization involves using ozone gas, which is an oxidizing agent, to eliminate microorganisms. It is an innovative approach that has gained attention due to its effective sterilization capabilities while being environmentally friendly.

Ozone works by disrupting the cellular structures of microorganisms, leading to their destruction. This method can be particularly beneficial for heat-sensitive instruments and materials that cannot withstand traditional sterilization methods such as steam or high-temperature processes.

In contrast, ethylene oxide has been widely used for many years but is not considered new; it's a recognized method that operates at low temperatures as well. Hydrogen peroxide plasma also provides a low-temperature option, but it has been in use longer than ozone technology. Formaldehyde has been traditionally utilized for sterilization as well but is less favored today due to safety concerns and a more complex process.

Ozone represents a more recent advancement, incorporating modern technology to enhance the sterilization process while addressing the limitations associated with older methods.
