Living Bioink for 3D-Printed Living Devices

A group of researchers from the Massachusetts Institute of Technology (MIT) generate living materials and devices by 3D printing genetically programmed bacterial cells. The living bioink can be used to print novel materials including logic gates and a living tattoo for chemical detection on human skin.

Magnetic-Field-Modulated Tuning of Light-Emitting Properties

Magnetic-Field-Modulated Tuning of Light-Emitting Properties

Researchers from Hong Kong Polytechnic University and the Hong Kong Polytechnic University Shenzhen Research Institute achieve remote and temporal tuning of luminescence intensity and wavelength in green- and blue-emissive piezophosphors by modulating the magnetic field. This novel method is promising for applications in magnetic optical sensing, piezophotonics, energy harvesting, nondestructive environmental surveillance, novel light sources, and displays.
