An Investigation of the Effectiveness of a Sterilization Device Using Heat and Ultraviolet Light Radiation

Abstract

Background: Paper papers and banknotes are known to be possible vectors for infections, and the incredible COVID-19 pandemic has highlighted the critical necessity for efficient sterilization procedures. This research attempts to create a hybrid sterilization device that utilizes heat and ultraviolet (UV) light radiation. It employs the Design Science Research Method (DSRM) to tackle this urgent requirement.

Methodology: The study follows the six-step DSRM framework, which begins with problem and motive identification, then defines solution aims, designs and constructs the device, and lastly assesses the system to prove its effectiveness. UV port, heat drawer, and control panel are the three primary components that constitute the prototype. To determine the effectiveness of the treatment, relevant microbiological strains, such as fungi, Gram-negative and Gram-positive bacteria, and other viruses were exposed to pre-contaminated papers at different intervals to heat and ultraviolet light.

Results: The sterilization device that was developed displayed noteworthy effectiveness in withholding microbial contamination from paper documents. The device's effectiveness in sterilizing paper materials and ensuring their safe handling was demonstrated through an analysis of CFU reductions, which indicated a significant decrease when compared to untreated controls. A better result was seen when heat and ultraviolet light radiation were used together in a hybrid method.

Conclusion: The study shows a brand-new hybrid sterilization device designed specifically for paper documents. This meets an urgent need that has become even more important since the COVID-19 pandemic. The heat-UV radiation from this gadget eliminates bacteria, lowering the risk of sickness and making paper goods safer. The DSRM framework can help to construct an organized strategy for conceiving, creating, and assessing innovative solutions to real-world problems.
