Researchers use gold nanorod scattering to identify immune system's 'killer and savior'

Every biological system is naturally equipped with a defense mechanism to protect against abnormal changes caused by either local, environmental, or biochemical alteration. White blood cells (WBC) play the role of such a ...

Highly selective membranes: Researchers discover how water can affect its own filtration

Membranes with microscopic pores are useful for water filtration. The effect of pore size on water filtration is well-understood, as is the role of ions, charged atoms that interact with the membrane. For the first time, ...
