Abstract

Groundbreaking knowledge at the nanoscale has been developed in many functional and industrial situations. Nanoscale colour recognition sensors have been developed by researchers in order to offer new ways to identify harmful germs. This study objective was to evaluate the ability of nano-biosensors colour indicators to identify nosocomial infection reservoirs.

Method: The enquiry was conducted in a semi-experimental environment for a month. Samples were obtained both prior to and during standard disinfection. The final findings were described as both clean and infected. There were 400 cases in the sample, 10 different types of equipment were employed, and sampling was done.

Results: The results showed high contamination of the studied surfaces. Moreover, 55% of the samples were infected before disinfection, which was reduced to 36.5% after routine disinfection.

Conclusion: The findings show that this tool has the necessary sensitivity, and we can introduce it as a standard tool for microbial contamination in the future; however, the aim was not to identify the type of microorganism.
