Nanosized drug delivery systems take a leap forward
19:03 November 3, 2009 PST

Blood vessels that supply tumors are more porous than normal vessels, makes nanoscale drug delivery systems a particularly attractive prospect. If properly engineered, nanoparticles can in fact get inside a tumor, targeting it precisely and allowing much higher drug dosages as they reduce side effects to a minimum. Two recent studies featured in the latest issue of the journal Nature Materials specifically address these issues and give us promising leads in the fight against cancer. Read More
Gizcast #11: bone conduction hearing implants, targeted chemotherapy and the electric car stampede that's storming Frankfurt

In this week's Gizcast, Geoffrey Baird speaks with audiologist Anthea Arkcoll about a new type of hearing aid that bypasses the ear altogether and uses bone conduction technology to send a direct signal to the auditory nerve. Then Loz Blain wraps up with some of the most interesting electric and green car concepts the Giz team are drooling over in Frankfurt, and a quick look at a medical device that could give doctors a new way to fight stubborn cancer tumours.

Targeted chemotherapy - fighting cancer without the side effects

A Silicon Valley entrepreneur, after watching helplessly through his sister's painful and terminal battle with cancer, has spent the last 9 years working on a system that lets doctors cut off blood flow to tumors, isolating them from the rest of the body and allowing the injection of a targeted dose of high intensity chemotherapy. Since the chemo drugs aren't let loose around the rest of the body, the usual devastating side-effects aren't an issue - and the drug dosage at the tumor site can be safely administered at a much higher concentration than usual. The IsoFlow Isolation Catheter has just received FDA marketing approval in the USA. Read More
Biodegradeable nanoparticles promise end to toxic chemotherapy treatments
03:23 June 19, 2009 PDT

Researchers at the University of Central Florida have engineered nanoparticles that can target and destroy cancerous cells, delivering a chemotherapeutic drug directly to a tumor without harming healthy cells. This technology could not only mean the end of toxic, whole-body chemotherapy, but also provide a diagnostic role in the early detection of cancer. Read More
