Abstract

A fluid channel system for examining cells may comprise a chamber filled with at least one photopolymerized hydrogel and/or one polymerized photodepolymerizable hydrogel to at least 90% capacity. The chamber may open exclusively towards at least one fluid channel via at least two openings. The at least one fluid channel and the chamber may each be in the form of a hollow space in a substrate, and each fluid channel may have two openings to the outside. In an embodiment, the system may comprise a hollow space in a substrate with at least one photopolymerized hydrogel and/or one polymerized photodepolymerizable hydrogel may be arranged and structured such that at least one fluid channel and a coherent hydrogel structure are formed. The hydrogel structure may adjoin the at least one fluid channel at two separate surface areas and connect to the outside exclusively via the at least one fluid channel.
