stericelectrostatic

Stericelectrostatic is a term used to describe a family of technologies and methods that combine sterilization or disinfection with electrostatic charging to improve contact between a sterilizing agent and microorganisms on surfaces or in air. The concept is used in settings where rapid coverage and reduced waste are desirable, such as healthcare facilities and pharmaceutical manufacturing.

Devices apply a controlled electrostatic charge to droplets or particles of a disinfectant or sterilant, causing them to be attracted to surfaces and to wrap around complex geometries. The charge can improve deposition efficiency and reduce required concentrations by concentrating the agent on target areas.

Common applications include handheld or benchtop electrostatic sprayers for room disinfection, surface sterilization in cleanrooms, and air decontamination using charged aerosols. The systems are used with oxidizing agents such as hydrogen peroxide or with quaternary ammonium compounds, depending on the design.

Limitations include equipment cost, need for trained operators, potential safety concerns with aerosolized disinfectants, and variable effectiveness on porous or irregular surfaces. Efficacy depends on proper coverage, dwell time, environmental conditions, and compatibility with materials.

The term is not universally standardized; components of electrostatic spray and surface sterilization have existed for decades, and stericelectrostatic is used descriptively in some industry literature and vendor materials. Ongoing research aims to optimize charge control, droplet size, and material compatibility.
