I'm making a scientific instrument that takes pictures of little particles that are in a liquid. It works by pushing some liquid that has debris in it through a filter and then taking pictures of the top of the filter to see what didn't go through. Imagine a gold prospector dumping sand and rocks in a sieve and then shaking the small stuff through the pores. The bigger rocks stay behind and are examined. Same thing here but on a smaller scale.

One key innovation here is that we have a unique filter. Instead of something that looks like a white coffee filter, we have a tiny square chip about the size of a fingernail with a million microscopic holes drilled through in a hexagonal grid, though you couldn't see the grid without a microscope. Pictures of the grid are reminiscent of a bee hive honeycomb.

Some advantages over our competitors are speed, simplicity, the ability to use less sample and the ability to capture smaller particles.
