Hi, I'm new here and just looking for a wee bit of advice. I am currently planning an investigation on the effectiveness of antibacterial hand washes and not decided on how to go about it. I can either have people wash their hands and then place their fingertips on an agar plate and count colonies (if any), make bore holes in the agar and drop some of the hand wash in and then measure the clear zone or I can soak assay discs in the hand wash and place it on to an agar plate that has a culture of bacteria.What do you think would be the best?
Thank you
