Programmed Nanorobots Seek And Destroy Cancer Tumors

Nanorobots have been successfully programmed to shrink tumors by cutting off their blood supply. This major advancement came from Arizona State University (ASU) scientists, in collaboration with researchers from the National Center for Nanoscience and Technology (NCNST), of the Chinese Academy of Sciences. The demonstration of the technology, the first-of-its-kind study in mammals, used breast […]

Laser Triggered Nanoshells Deliver Drugs Inside Tumors

Researchers have developed a method for delivering cancer-killing drugs inside tumors with gold nanoparticles they can activate remotely using a laser. The researchers employed gold nanoshells to deliver toxic doses of two drugs — lapatinib and docetaxel — inside breast cancer cells, showing they could use a laser to remotely trigger the particles to release […]

Nanoporous Membranes With Tunable Molecular Separation

Novel membranes with selectivity that can be switched dynamically with the help of light have been developed by researchers at Karlsruhe Institute of Technology (KIT) and Universität Hannover. Azobenzene molecules were integrated into membranes made of metal-organic frameworks (MOFs). Depending on the irradiation wavelength, these azobenzene units in the MOFs adopt a stretched or angular […]

First Artificial Molecular Pump Uses Non-equilibrium Chemistry

An artificial molecular pump that uses molecules to pump other molecules has been developed by scientists at Northwestern University. The tiny machine, inspired by nature, may some day be used to power other molecular machines, such as artificial muscles. The new mechanism simulates the pumping of life-sustaining proteins which move small molecules inside living cells […]
