From Door Knobs to Phone Screens: Identifying Microbial Contaminants in Daily Life

We will demonstrate the processes used to isolate and detect microbial contaminants using bacterial strains in petri dishes. The color, size, and grouping are different for each species of bacteria. Swabs of everyday objects like phones, doorknobs, or bathroom stalls will be grown on petri dishes, allowing participants to identify which microbes they encounter daily. Additionally, the demonstration will include the process of using magnetic nanoparticles (MNPs) to capture bacterial contaminants present in everyday encounters.
