acoustic biosensor

Hi, please don’t kill me for probably being naive to slightly rude to ask via this forum. I am an artist working with sound and for a project I would like to produce a scenerie in which I would need an acoustic biosensor to measure the population of microbs on a material (material is adaptable). So my question is if you could provide any information about how to start, which technology, material could be of use. I would be eternally thankful for any hints. All the best, martina

Please describe an “acoustic biosensor”.

Most people use microscopes to study microbes.

Do you want to record the sounds the microbes make? Or do you want to measure the microbes somehow and then use that to produce sound?
