Body Builders

The latest issue of Johns Hopkins University Engineering magazine features the article “Body Builders“ by Sara Achenbach. The article mentions the work of several Johns Hopkins University and Institute for NanoBioTechnology affiliated faculty members. Work highlighted includes that of Andreas Andreou (Electrical and Computer Engineering); Marc Ostermeier (Chemical and Biomolecular Engineering); Michael Yu (Materials Science and Engineering); Jennifer Elisseeff (Biomedical Engineering Institute); and Nitish Thakor (Biomedical Engineering).

Artificial Intelligence: Andreou’s team has developed a silicon cortex using nanoscale 3-D silicon on insulator complementary metal oxide semiconductor technology. By stacking super thin microchips in this nano-sized cortex, his groups has simulated more closely than before the natural circuitry of the brain.

Protein Switches: Ostermeier’s group is looking at the ways protein switches work to respond to complex signals. His work is funded by grants from National Institutes of Health, National Science Foundation and an INBT grant.

Tissue Scaffolds: Funded in part by a National Science Foundation CAREER Award, Yu is creating biomedical applications for modified collagen to prevent the formation of scar tissue and to prevent organ transplant rejection.

Hydrogel Scaffolds: Elisseeff uses hydrogel scaffolds to develop artificial adhesives for the eye to repair corneal damage and help close incisions following cataract surgery. Another Elisseef led team is investigating methods of creating artificial cartilage.

Robotic Hands: Thakor and colleagues are testing some brain-controlled robotic prosthetic hands with very human-like qualities. This work is funded by the Defense Advanced Research Projects Agency through the Johns Hopkins Applied Physics Lab.
