About the Company

See protein, DNA and RNA molecules that make life work, in nanoparticles, viruses, bacteria, cells and tissue.

We believe that understanding science at a molecular level will fundamentally allow you to unlock new discoveries, so we created our flagship product, The Nanoimager. We built the world's first desktop compatible compact super-resolution microscope, but we did it our way.

Our teams have a restless enthusiasm to bring technologies like super-resolution to a new community of researchers and we continue working until barriers of accessibility and affordability are addressed. Our mission is to ensure research and collaboration tools are available to those willing to ask why or how things are the way they are and answer questions never asked before.

We can't wait to see and hear about what new questions you will ask!
