Cancer surgery is evolving quickly as researchers around the globe develop new techniques. The Lebanese University has created a robotic manipulator that precisely positions a laser used in photodynamic therapy. The laser activates drugs given to the patient, causing these photosensitizer drugs to activate and destroy cancerous growths. Researchers in Lebanon use National Instruments’ PCI-7334 to control the four stepper motors that move the laser head. Light must come from various angles to fully destroy the cancerous cells, so the head goes through many steps during the treatment.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
