The therapies work by delivering genes into the patients’ cells, which then produce therapeutic proteins to treat the affliction. When determining

Irvine, Calif., Oct. 7, 2020 – Electrical engineers, computer scientists and biomedical engineers at the University of California, Irvine have created a new lab-on-a-chip that can help study tumor heterogeneity to reduce resistance to cancer therapies. In a paper published today in Advanced Biosystems, the researchers describe how they combined artificial intelligence, microfluidics and nanoparticle

A growing area of medicine looks at how cellular binding observed in nature – where molecules like viruses or proteins bind to specific receptors on a cell – can be mimicked to aid drug delivery. Those developing targeted drug therapies aim to recreate this precise binding to develop nano-sized drug carriers that attach only to

The key to this lies in thorium-229, an atomic nucleus whose lowest excited state has very low energy. A research team from

EVANSTON, Ill. — Northwestern University researchers are casting a net for nanoparticles. The team has discovered a new, rapid method for fabricating nanoparticles from a simple, self-assembling polymer. The novel method presents new possibilities for diverse applications, including water purification, diagnostics and rapidly generating vaccine formulations, which typically require many different types of molecules to

PHOENIX and TUCSON, Ariz. — Oct. 5, 2020 — Avery Therapeutics Inc. of Tucson has developed an engineered heart tissue, a lab-grown cardiac membrane that can help heal the heart, either following a heart attack or as a result of progressive heart disease. The heart tissue, called MyCardia™, could revolutionize the treatment of cardiovascular disease,

Using specialized nanoparticles, MIT engineers have developed a way to turn off specific genes in cells of the bone marrow, which play an important role in producing blood cells. These particles could be tailored to help treat heart disease or to boost the yield of stem cells in patients who need stem cell transplants, the

Long known as the hardest of all natural materials, diamonds are also exceptional thermal conductors and electrical insulators. Now, researchers have discovered a way to tweak tiny needles of diamond in a controlled way to transform their electronic properties, dialing them from insulating, through semiconducting, all the way to highly conductive, or metallic. This can
