Implantable neuromodulation devices such as deep brain stimulators and vagus nerve stimulators, are widely used to treat neurological diseases. Most devices are composed of rigid probes that limit spatial resolution and increase ...
The present variants of cancer immunotherapy such as immune checkpoint blockades only benefit a small subset of patients due to its immunosuppressive tumor microenvironment. The capacity to vaccinate tumors and reduce immunosuppression ...
Surgery prompted by automobile accidents, combat wounds, cancer treatment and other conditions can lead to bone infections that are difficult to treat and can delay healing until they are resolved. Now, researchers have a ...

A gel (from the lat. gelu—freezing, cold, ice or gelatus—frozen, immobile) is a solid, jelly-like material that can have properties ranging from soft and weak to hard and tough. Gels are defined as a substantially dilute cross-linked system, which exhibits no flow when in the steady-state. By weight, gels are mostly liquid, yet they behave like solids due to a three-dimensional cross-linked network within the liquid. It is the crosslinks within the fluid that give a gel its structure (hardness) and contribute to stickiness (tack). In this way gels are a dispersion of molecules of a liquid within a solid in which the solid is the continuous phase and the liquid is the discontinuous phase.
