Universal optothermal micro/nanoscale rotors

The fundamental rotation of micro and nano-objects is crucial for the functionality of micro and nanorobotics, as well as three-dimensional imaging and lab-on-a-chip systems. These optical rotation methods can function fuel-free ...

New biomaterial gets 'sticky' with stem cells

(Phys.org)—Just like the bones that hold up your body, your cells have their own scaffolding that holds them up. This scaffolding, known as the extracellular matrix, or ECM, not only props up cells but also provides attachment ...

A corny turn for biofuels from switchgrass

Many experts believe that advanced biofuels made from cellulosic biomass are the most promising alternative to petroleum-based liquid fuels for a renewable, clean, green, domestic source of transportation energy. Nature, ...
