Scientists develop new way to detect threatening nanoparticles in food

Over the last few years, the use of nanomaterials for water treatment, food packaging, pesticides, cosmetics and other industries has increased. For example, farmers have used silver nanoparticles as a pesticide because of their capability to suppress the growth of harmful organisms. However, a growing concern is that these particles could pose a potential health risk to humans and the environment.

New drug-delivery strategy for central vision loss

Johns Hopkins biomedical engineers have teamed up with clinicians to create a new drug-delivery strategy for a type of central vision loss caused by blood vessel growth at the back of the eye, where such growth should not occur.

New treatment technique uses nanoparticles to attack cancer

Researchers at the University of Georgia are developing a new treatment technique that uses nanoparticles to reprogram immune cells so they are able to recognize and attack cancer. The findings were published recently in the early online edition of ACS Nano.

Scientist develop mathematical model that predicts how individuals respond to cancer treatment

Vittorio Cristini, PhD, uses the example of an airplane to explain what he does in cancer research. "Before calculus," he says, "people couldn't really design a plane that would fly. You can do it by trial and error, but it would probably take centuries." Dr. Cristini has a faster way to try to understand cancer treatment. Like airplane designers today, he uses a mathematical model.

Scientists use nanoparticles to regulate DNA interactions in self-assembly, drug-delivery

A team of chemists in SU's Cf ollege oArts and Scientists has used a temperature-sensitive polymer to regulate DNA interactions in both a DNA-mediated assembly system and a DNA-encoded drug-delivery system.

High mobility group (HMG) genes and cancer: an interview with Dr. Linda Resar, Johns Hopkins University School of Medicine

High mobility group A genes are highly expressed in all aggressive cancers studied to date. These genes encode the high mobility group A (HMGA) proteins. In other words, these genes provide the genetic “code” necessary to produce HMGA proteins.

ASU expert receives $1.6 million grant to advance microscopy imaging research

At Arizona State University's Biodesign Institute, Nongjian (NJ) Tao has been designing advanced microscopy methods with the ambitious aim of capturing molecular-scale phenomena in living systems. The new techniques, which combine multiple imaging modalities, are poised to revolutionize the study of biology and the development of new drugs.

Study suggests silicon nanocrystals may be safe tool for diagnostic imaging in humans

Tiny silicon crystals caused no health problems in monkeys three months after large doses were injected, marking a step forward in the quest to bring such materials into clinics as biomedical imaging agents, according to a new study.

Solar-powered sterilization system could be boon for people who lack adequate sanitation

Rice University nanotechnology researchers have unveiled a solar-powered sterilization system that could be a boon for more than 2.5 billion people who lack adequate sanitation. The "solar steam" sterilization system uses nanomaterials to convert as much as 80 percent of the energy in sunlight into germ-killing heat.

Gold nanofibers in engineered heart tissue can enhance electrical signalling, find researchers

Heart tissue sustains irreparable damage in the wake of a heart attack. Because cells in the heart cannot multiply and the cardiac muscle contains few stem cells, the tissue is unable to repair itself - it becomes fibrotic and cannot contract properly.

New noninvasive technique for tracking stem cells after transplantation

A new, noninvasive technique for tracking stem cells after transplantation - developed by a cross-disciplinary team of radiologists, chemists, statisticians and materials scientists at the Stanford University School of Medicine - could help surgeons determine whether a procedure to repair injured or worn-out knees is successful.

New concept could improve cancer drug delivery

Researchers have developed a concept to potentially improve delivery of drugs for cancer treatment using nanoparticles that concentrate and expand in the presence of higher acidity found in tumor cells.

New approach delivers RNA drugs to silence malfunctioning genes

Silencing genes that have malfunctioned is an important approach for treating diseases such as cancer and heart disease. One effective approach is to deliver drugs made from small molecules of ribonucleic acid, or RNA, which are used to inhibit gene expression. The drugs, in essence, mimic a natural process called RNA interference.

Cancer immunotherapies promise to be a new tool in fight against cancer

Drugs that direct a cancer patient's immune system to eradicate her or his disease, known as cancer immunotherapies, promise to be a new tool in the fight against cancer. Since the Koch Institute's inception, exploring the close relationship between the immune system and cancer has been one of the Institute's priority research areas.
