BME PhD candidate Kilean Lucas takes second place at the Hajim School's Art of Science Competition

Blood Cells by Scanning Electron Microscope

“You see some phenomenal things under a scanning electron microscope,” says Kilean Lucas.

Such as the image above, which the PhD student took of a single human red blood cell, captured among several white blood cells on a silicon nanomembrane developed in the lab of Lucas’ advisor, James McGrath, professor of biomedical engineering.

Lucas is studying how the ability of these nanomembranes to separate and filter out particles that differ by mere microns in size could lead to medical breakthroughs. For example, immature red blood cells separated from mature red blood cells could be harvested and seeded into bioreactors as a new way to replenish blood banks.

Or all the white blood cells could be filtered out from a patient’s blood sample. There are many forms of white blood cells, each responding in different ways to different threats. The proportion of each type of white blood cell in a given sample could be used to give a rough diagnosis of the body’s response to disease.

Lucas said it was not easy deciding which of several images from his research to submit to the Art of Science competition. “This one had a very good balance of being far enough out where we could see multiple types of cells, but not so close that we’re only looking at one or two,” Lucas says. “What I tried to do with the pseudo coloring is to emphasize that variety.”

He hopes this image will convey to people how “stunning it is, in and of itself, that we’re able to capture all of these cells out of blood, a very complex solution” – in ways that could change peoples’ lives.
