With every passing day, human technology becomes more refined and we become slightly better equipped to look deeper into biological processes and molecular and cellular structures, thereby gaining greater understanding of mechanisms underlying diseases such as cancer, Alzheimer's, and others.

Their technique involves placing wet cells on a collagen-coated wet substrate with microholes, which in turn is on top of a cell culture medium reservoir. The cells are then covered with a single layer of graphene. It is the graphene that is expected to protect the cells from desiccation and cell membranes from degradation.
