Pressure Cylinder Controlled Release Valve, Alexa Dominique Balbuena

Biomedical Engineering

This project aims to integrate an automatic gas release system in a pre-existing scaffold fabrication process for tissue engineering applications.

To form the proper scaffold structure, the fabrication process is heavily influenced by the change in its surrounding pressure. The current production involves a pressure transducer and electric valve that is managed manually to create a suitable pressure environment for the scaffold. This method, although functional, proves to be ineffective when creating several batches; the user needs to constantly monitor the developing pressure profile and alter voltage parameters accordingly to create a linear gas release under a predetermined slope.

A Novel In-House Design Of A Bioreactor For The Modeling Of An In Vitro Blood Brain Barrier Model, Ian Mahaffey

Biomedical Engineering

The blood brain barrier is the protector of the central nervous system and a physical barrier that functions to regulate the substances that can pass in and out of the brain; it is the function and integrity of this system that keeps the homeostasis of the central nervous system. Yet this shield against foreign invaders in the blood also prevents drugs designed for treatment of various ailments of the central nervous system from reaching their target in the brain. Developing drugs that can pass through this barrier, and understanding it’s function has become an area of increasing interest. Many researchers …
