In recent years, microbial contamination has increased, contributing to the spread of infectious diseases. Avoiding microbial contamination is a complex process; advanced sterilization techniques are essential in food and pharmaceutical industries to prevent contamination. In the past, conventional sterilization methods were used, but they have several limitations, including ineffective microbial inactivation, high salt requirements, excessive energy consumption, material degradation, and spoilage. This chapter explores the synergistic relationship between quantum catalysis and supercritical carbon dioxide (scCO2) technologies for enhanced sterilization. Quantum catalysts harness quantum energy in scCO2 reactions to deactivate microorganisms at the molecular level. Scientists examine the fundamental mechanisms by which quantum catalysts induce intracellular damage and cell lysis, ultimately leading to the breakdown of microbial cell walls and cell death. Advanced techniques—including spectroscopy, electron microscopy, and viability studies—are employed to demonstrate the effectiveness of this approach. The chapter emphasizes the impact of various parameters, assessing how temperature, pressure, and catalyst characteristics affect the efficacy of microbial deactivation to optimize these processes. The results indicate that quantum catalysts offer a residue-free, non-thermal sterilization method, significantly reducing CO2 usage and processing time by lowering the activation energy required for microbial inactivation. This innovation presents a sustainable and efficient alternative to traditional sterilization techniques, with potential applications in pharmaceuticals, food safety, and biomedical fields. By integrating quantum catalysis with supercritical carbon dioxide, this chapter reveals a transformative approach to microorganism decontamination, paving the way for further research into large-scale sterilization using quantum-enhanced antibacterial technology.
