Using a NOVEL Method to ULTRAVIOLET Sterilization of COMPUTER KEYBOARDS

Overview

USING A NOVEL METHOD TO ULTRAVIOLET STERILIZATION OF COMPUTER KEYBOARDS Bacteria cells' genomes can be inactivated by sterilization; a common method used is UVC sterilization. The purpose of this experiment was to determine if a 3D printed design can aid in bacterial sterilization on computer keyboards. UVC is a commonly used method for germicidal sterilization. Using a 3D printing software, Tinkercad , a design was created to cover a keyboard. Once the original design was made, they were spliced into six smaller pieces using the same software. Once they were printed they were glued tightly together, the UVC light was attached to the top of the cover. 20 plates were then cultured after swabbing the keyboard. Once the keyboard was disinfected using the cover another 20 cultures were made swabbing the keyboard. The cultures before the sterilization revealed more bacteria then the cultures after the sterilization using the design.. The design assisted in the inactivation of the bacterial genome making the bacteria inactive and nonpathogenic. The cover can be used for any keyboard where cleaning does not happen frequently. Therefore, the method of sterilization worked.
