Wireless therapeutic endoscopic capsule: in vivo experiment.

Background And Study Aim: Capsule endoscopy is becoming well established as a diagnostic technique for the gastrointestinal tract. Nevertheless swallowable capsule devices that can effectively perform surgical and therapeutic interventions have not yet been developed. Such devices would also be a valuable support for natural orifice transluminal endoscopic surgery (NOTES).

Characterization of an alginate-based drug delivery system for neurological applications.

This paper presents a drug delivery system based on alginate gels. The biocompatibility, the flexibility in size and shape, and the ability to entrap biomolecules make alginate-based systems ideal for in vivo drug delivery. Specifically, by considering the target application of neural regeneration and neuroprotection, the issue of biocompatibility as well as morphologic compatibility (e.
