Diagnosis technique that filters out harmful cells could lead to a "dialysis machine" for cancer

A new cancer diagnosis technique that separates cancerous cells from blood may inspire a new form of treatment for the disease. A researcher at Australia's University of New South Wales (UNSW)who helped devise the test says it could potentially be scaled up to cleanse meaningful quantities of blood, which could then be reintroduced into the body to battle different forms of the disease.

Liquid metal "Nano-Terminators" could signal judgement day for cancer

Scientists are increasingly turning to nanoparticles in search of new ways to treat cancer. Tiny nanorobots that wade through the bloodstream and microscopic particles that blow up diseased cells are a couple of menacing examples. But none sound quite so ominous as a new technique under development at North Carolina State University (NCSU). Its researchers have designed liquid metal particles they describe as "Nano-Terminators" that latch onto cancer cells to more effectively deliver drugs that kill them off.

Injectable, intelligent gel targets cancer at the source

Enlisting the body's naturally produced T cells to fight off cancer is an immunotherapy technique that has shown early promise in clinical trials. But one limitation is that these cells generally lack the firepower to do the job on their own, meaning they need to be modified and reintroduced to the bloodstream to have a real impact. Researchers may now have discovered a more efficient way forward, with the development of a T cell-loaded biogel that can be injected directly into the tumor for a more targeted, less laborious approach to immunotherapy.

Ultrasound prises open blood-brain barrier to deliver chemotherapy in a world first

The blood-brain barrier is an almost impenetrable membrane that surrounds vessels in the brain and stops harmful particles from entering. The trouble is that it doesn't discriminate, at the same time making it very difficult for beneficial molecules like medication to pass through. But researchers have now non-invasively breached the barrier for the first time in a human subject, delivering chemotherapy drugs to a brain cancer patient with a high level of precision and paving the way for improved treatments and fewer side effects for sufferers of neurological disorders.

"Lab-in-a-briefcase" designed to bring early cancer detection to developing countries

Detecting cancer early is difficult enough at the best of times, but the problem is compounded in developing countries where patients don't always have access to advanced diagnostics equipment. A team of UK-based scientists has developed a new tool that could greatly assist those taking the fight to cancer in these regions. Billed as a lab-in-a-briefcase, the low-cost, portable diagnostics tool works similarly to a pregnancy test and can detect cancer biomarkers in as little as 15 minutes.
