Nanoparticles

Urine tests that pick up biomarkers of cancer are one way scientists hope to diagnose the disease early, and MIT researchers have demonstrated a particularly promising example that could give efforts to diagnose early-stage lung cancer a huge boost.

Scientists have managed to copy one of cancer's strategies to hide from the immune system, and use it for good. They made new microparticles that permanently prevent transplanted tissue or even whole limbs from being rejected by the immune system.

If you like spicy foods, then you're probably aware of the claimed anti-inflammatory qualities of turmeric. Scientists have now developed what they say is a more effective way of biologically delivering turmeric's active compound, curcumin.

Two new studies are offering novel insights into celiac disease. One study is suggesting immune responses to gluten lead to neurological damage, while another offers hope for a cure demonstrating a nanoparticle treatment can induce immune tolerance.

Atherosclerotic plaque-deposits on the inner walls of arteries are a frequent cause of heart attacks and strokes. A newly-developed nanoparticle could help minimize those deposits, as it prompts the body's own cells to "eat" them.

In 2018, researchers created the world’s fastest-spinning object that reached 60 billion rpm – now that seems like the teacup ride at Disneyland. The same team has broken its own record, creating a new nano-scale rotor that spins five times faster.

Causing the death of cancer cells while leaving healthy ones in tact is central to the goal of safer, more effective forms of treatment for the disease, and scientists have now come up with one that leans heavily a common household item – salt.

One of humanity’s biggest threats is also the smallest – bacteria. But now, researchers at RMIT in Australia have found a new method for killing these superbugs that they can’t resist – magnetic nanoparticles that physically tear them to shreds.

A new gold-doped antibacterial nanomesh has been designed as a more effective alternative to pills or needles.

Researchers at Griffith University in Australia have used the CRISPR-Cas9 gene-editing system to effectively cure cervical cancer in mice.

Cancer drugs are getting more effective at killing tumors, but there’s one big problem: many work like a shotgun blast and harm healthy cells as well. Researchers from Georgia Tech have now developed a new way to deliver drugs only to where they need to be, using nanoscale “glass” bottles.

A nano-vaccine is showing promising results in treating skin cancer in mouse models. The vaccine encases two new cancer drugs inside a nanoparticle, with initial experiments revealing it can stimulate the immune system to kill melanoma, and act as a preventative vaccine.
