Researchers have developed a cutting-edge drug delivery system that relies on two separate “logic gates,” each of which acts as a safety switch to prevent the release of a drug unless a particular condition is fulfilled. This approach helps to reduce side effects that are typical of many cancer treatments, which kill not only cancer cells but also cells throughout the body.
Researchers have developed a conductive ink made from a special type of material called MXene, which was used by the researchers to print components for electronic devices. The ink is additive-free, which means it can print the finished devices in one step without any special finishing treatments.

Researchers have explored in unprecedented detail catalysts that allow some chemical reactions, which normally require high heat, to proceed at room temperature. The energy-saving catalysts use sunlight to excite localized surface plasmons – oscillations of groups of electrons on the surface of certain metal nanoparticles.

Researchers have proposed and demonstrated a phonon laser using an optically levitated nanoparticle. A phonon is a quantum of energy associated with a sound wave. The researchers studied the mechanical vibrations of the nanoparticle, which was levitated against gravity by the force of radiation at the focus of an optical laser beam.

Scientists at the U.S. Naval Research Laboratory have developed and patented the fabrication of a transparent, luminescent material they say could give smartphone and television screens flexible, stretchable, and shatterproof properties.

Engineers have developed a novel fabrication method to create dyed threads that change color when they detect a variety of gases. The researchers demonstrated that the threads can be read visually or by use of a smartphone camera to detect changes of color due to analytes as low as 50 parts per million. These gas-detecting threads could be used in medical, workplace, military, and rescueaenvironments.
