Delivery systems and methods for forming and delivering biomaterials from two components are described herein. In particular, apparatus and methods for performing controlled delivery of multicomponent delivery of biomaterials into or onto a body part, such as a body lumen are described. More specifically, in some embodiments, the apparatus and methods are directed towards controlled delivery of micro-volumes of biomaterials into or onto a target location, the micro-volumes being defined as 0.001 mL-1 mL (or 1 μL-1,000 μL) of volume.
