Nanoparticles Enter Living Cells To Gather Cancer Clues

A new imaging technique sends nanoparticles into living cells to reveal important information about cell structure, including how tumor cells physically change as they form a tumor. The technique captures mechanical properties in living subjects that probe fundamental relationships between physics and in vivo (in a living organism) biology. “We…Continue readingNanoparticles Enter Living Cells To Gather Cancer Clues

Supersensitive Nanomaterials For Targeted Drug Delivery Developed

In 1900, German physician Paul Ehrlich came up with the idea of a “magic bullet.” The concept was to inject a patient with smart particles capable of finding, recognizing, and treating disease. Medical science has pursued the magic bullet ever since. Russian researchers from the Moscow Institute of Physics and…Continue readingSupersensitive Nanomaterials For Targeted Drug Delivery Developed

Sono-optogenetics: A Less Invasive Way To Study The Brain

Injectable nanoparticles that convert sound waves, which can easily penetrate into the brain, into light, have been developed by Stanford researchers[1]. Optogenetics, a tool for controlling neurons with light, has given neuroscientists the ability to flip brain cells on and off more or less at will, revolutionizing neuroscience. Yet the…Continue readingSono-optogenetics: A Less Invasive Way To Study The Brain

Nano Superballs Offer Refined Control Of Optogenetics

New nanoparticles and nanoclusters dubbed “superballs” offer more control to optogenetics. Optogenetics is a technique that uses light to control cells within living tissue. The biological technique controls cells in tissues genetically modified for light sensitivity. Drawbacks are that the light can activate several genes at once and that it…Continue readingNano Superballs Offer Refined Control Of Optogenetics

Sprayable Gel Could Help Fight Cancer Recurrence After Surgery

A UCLA-led research team has developed a sprayed gel embedded with immune-boosting drugs that could help cancer tumour recurrence after surgery. Many people who are diagnosed with cancer will undergo some type of surgery to treat their disease — almost 95 percent of people with early-diagnosed breast cancer will require…Continue readingSprayable Gel Could Help Fight Cancer Recurrence After Surgery

Injectable Nanomaterial Delivers Arthritis Drugs Throughout Cartilage

Osteoarthritis, a disease that causes severe joint pain, affects more than 20 million people in the United States. Some drug treatments can help alleviate the pain, but there are no treatments that can reverse or slow the cartilage breakdown associated with the disease. In an advance that could improve the…Continue readingInjectable Nanomaterial Delivers Arthritis Drugs Throughout Cartilage

Cancer Identity Nanoparticles Makes It Easier To Find A Tumor’s ‘Address’

A technology aimed at making it easier to deliver cancer treatment to the right “address” in the body while also easing the painful side effects of chemotherapy on patients has been developed by researchers at Purdue University. One of the big issues with chemotherapy is that most treatment approaches focus…Continue readingCancer Identity Nanoparticles Makes It Easier To Find A Tumor’s ‘Address’
