Vaccination with a dissolving microneedle array

Scientists have demonstrated the utility of dissolving microneedle arrays designs for the lymph node delivery of amphiphilic vaccines released upon skin insertion.

3D-printing transparent glass

Researchers have developed a method of 3D-printing silica suspensions that are subsequently densified into transparent silica glass.

Nanoparticles take a bite out of infections

Researchers are working with a smart polymer that changes color and activates natural antimicrobial enzymes when bacterial contamination is detected.

Tuning thermal expansion with origami metamaterials

Scientists have combined experiments and simulations to demonstrate that origami metamaterials provide a new platform for the design of systems with a wide range of coefficients of thermal expansion.

Nanogenerator-powered acceleration sensor

Researchers have demonstrated a self-powered acceleration sensor based on liquid metal triboelectric nanogenerator, which was composed of an inner liquid metal droplet (mercury) and an outer acrylic shell.

Killing cancer in the heat of the moment

A new method efficiently transfers genes into cells, then activates them with light. This could lead to gene therapies for cancers.

Powerful new photodetector can enable optoelectronics advances

Researchers have fabricated a nanoscale photodetector that combines a unique fabrication method and light-trapping structures.
