Tiny “submarines” that speed independently through the stomach, use gastric acid for fuel (while rapidly neutralizing it), and release their cargo precisely at the desired pH: Though it may sound like ...

Stomach acid can sabotage certain drugs that need to work in the stomach, including some antibiotics. Researchers from the University of California, San Diego, have developed tiny motors that interact ...

WEST LAFAYETTE, Ind. -- Purdue University researchers have developed a new class of materials with a wide variety of potential applications, from coatings to repel liquids to membranes that could be ...

Continuing this pioneering effort toward enhanced motor-based site-specific delivery, the research team, led by Professors Joseph Wang and Liangfang Zhang at the Nanoengineering Department at ...

A recent review in the Chemical and Pharmaceutical Bulletin looks at the molecular design of pH-sensitive cationic lipids and their applications for various tissues and cell types. The researchers ...

Researchers at Arizona State University have uncovered a key scientific principle that governs how what's coated on the surfaces of engineered nanoparticles may ultimately control how they work in our ...

From ultra-sensitive sensors to shape-shifting implants, stimuli-responsive smart materials react reversibly to heat, light, stress, or pH. They could transform devices and therapies once issues in ...
