Abstract
The processing of inclusion bodies (IBs) into surfaces is of great interest for cell culture applications due to the combined physical and biological cues these particles provide. The arrangement of these IBs into defined and tunable micropatterns can be useful for basic research purposes regarding the mechanical properties needed for cell adhesion and migration, among other responses. There are several approaches that can be used when functionalizing a substrate with IBs, regarding both the strategy used and also the kind of surface-particle interaction. The interaction between surface and IB can be mainly of three types: physisorption, electrostatic or covalent. This interaction can be controlled by depositing an appropriate self-assembled monolayer (SAM) on top of a substrate as an interface. Furthermore, several strategies can be used to immobilize IBs on surfaces in various configurations, like random deposition, micrometric printed geometries or gradient patterns.
