We have developed novel shear-thinning biomaterials using silica nanoparticles, gelatin-based polymers and small molecules such as doxorubicin. Shear-thinning biomaterial technology offers enables polymers and drugs loaded inside such polymers to be easily delivered directly through catheters into target area for use, for example, in cancer therapy and immunotherapy. When a force above a certain threshold is applied to inject such materials, they “thin” and behaves as a semi-solid, allowing the material to readily flow through a catheter. When the force is removed, the material instantly becomes a soft solid with significant cohesive properties that prevent it from dislodging or breaking up.
