A team of scientists has developed a molecular propeller that enables unidirectional rotations on a material surface when energized. In nature, molecule propellers are vital in many biological applications ranging from the swimming bacteria to intracellular transport, but synthetic molecular propellers, like what has been developed, can operate in harsher environments and under a precise control.
UCLA researchers have developed a new technique for creating membrane filters that could offer a way for manufacturers to produce more effective and energy-efficient membranes using high-performance plastics, metal-organic frameworks, and carbon materials. To date, limitations in how filters are fabricated have prevented those materials from being viable in industrial production.

Many diagnostic tests require blood, but researchers funded by the National Institutes of Health have developed a skin patch with tiny needles that painlessly collect interstitial fluid for testing. Diagnostic tests can measure trace amounts of essential proteins or hormones in the blood called biomarkers. High or low levels of biomarkers are specific indicators for a disease.

Ambitious efforts are underway to map the presence and abundance of proteins in organs and tissues of the human body at the scale of single cells. But existing imaging methods are limited in their performance, their accessibility to researchers, or both. Now, researchers at Harvard's Wyss Institute for Biological Engineering and Harvard Medical School have developed a DNA-nanotechnology-based approach that enables the visualization of many proteins in the same sample.

Researchers at the University of Minnesota have discovered a cellular process that allows nanomaterial entry into cells. These findings reveal another mechanism for nanoparticle entry into cells and open up an avenue of studying the interplay among endocytosis, amino acids, and nanomaterial delivery.
