Reconstituting tissues from their cellular building blocks facilitates the modeling of morphogenesis, homeostasis and disease in vitro. Here we describe DNA-programmed assembly of cells (DPAC), a ...

Researchers have developed a simple process for producing near-perfect nanocrystals that will enable studies of physical and chemical properties that affect how nanoparticles interact with the world ...

With growing interest in using nanoparticles for everything from antibacterial socks to medical imaging to electronic devices, the need to understand the environmental, health and safety risks of ...
