Science Buddies: "Ask an Expert"

Hello I’m an Intern doing research on sterilization of surgical instruments for my summer project. Is there any way to measure the amount of microorganisms left on an instrument after an operation and after sterilization?

Hello,
Science Buddies Ask the Experts are for students in grades K-12 who are doing hands on science projects. If you are a student in those grades, please describe your science project in more detail, including your hypothesis and your experimental plan for testing that hypothesis. If you are not a student in grades K-12, there are other sites on the internet where your questions would be more appropriate. Thank you.
