Smart hydrogels

UD-developed smart gels deliver medicine on demand

Researchers at the University of Delaware have developed a “smart” hydrogel that can deliver medicine on demand, in response to mechanical force.

Over the past few decades, smart hydrogels have been created that respond to pH, temperature, DNA, light and other stimuli. (more…)

Promising Nanotechnology

Nanotechnology for drug delivery shows promise in treatment of pediatric leukemia

Nanotechnology developed by Delaware scientists could potentially deliver chemotherapy to children in a way that attacks cancer cells without harming healthy cells, greatly reducing side effects.

The work, conducted by researchers in the University of Delaware’s Department of Materials Science and Engineering and Nemours Center for Childhood Cancer Research, was published this month in the journal Molecular Pharmaceutics. (more…)

Inspired by Insects

For treatment of vocal fold disorders, UD researchers look to insect protein

A one-inch long grasshopper can leap a distance of about 20 inches. Cicadas can produce sound at about the same frequency as radio waves. Fleas measuring only millimeters can jump an astonishing 100 times their height in microseconds. How do they do it? They make use of a naturally occurring protein called resilin.

Resilin is a protein in the composite structures found in the leg and wing joints, and sound producing organs of insects. Highly elastic, it responds to exceptionally high rates of speed and demonstrates unmatched resilience after being stretched or deformed. (more…)
