A dental robotic testing simulator from Bristol University

Dr. Kazem Alemzadeh in the Bio-engineering research group of Bristol University's Department of Mechanical Engineering has invented a Dental Robotic Testing Simulator called 'Dento-Munch' that can replicate human chewing, in order to test dental materials. The design inspiration was based on a human skull (structure), a spider (general look) and an aircraft simulator (dynamics and control of chewing).

Nanomaterials key to new strategies for blocking metastasis

A new treatment strategy using targeted nanoparticles to block metastasis with anti-cancer drugs leads to good results using significantly lower doses of toxic chemotherapy, with less collateral damage to surrounding tissue, according to a collaborative team of researchers at the Center of Nanotechnology for Treatment, Understanding, and Monitoring of Cancer at the University of California, San Diego. In designing this system, the investigators, led by David Cheresh, Ph.D., have identified what may become a generic method for using nanotechnology to target metastasis.

Protein-cross-linked polymeric materials through site-selective bioconjugation

Researchers at the University of California, Berkeley (USA) have now developed a new strategy for the formation of hybrid materials from synthetic polymers and proteins. They have thus been able to fuse the specific biological functions of proteins with the advantageous bulk and processing properties of plastics.

New nanoparticles for targeting tumors

As a wide variety of nanoparticles continue to demonstrate their ability to improve the delivery of imaging agents and drugs to tumors, nanoparticle researchers have turned their attention to the challenge of systematically determining how a given nanoparticle’s physical and chemical characteristics affect its ability to target tumors. Such data could provide drug developers with guidelines to help them select the most effective type of nanoparticle for a given therapeutic or imaging application.
