In nanotechnology, a particle is defined as a small object that behaves as a whole unit in terms of its transport and properties. It is further classified according to size: in terms of diameter, fine particles cover a range between 100 and 2500 nanometers, while ultrafine particles, on the other hand, are sized between 1 and 100 nanometers.

New bio-mimicry method allows scientists to track cells in vivo using MRI during preclinical, clinical trials

Researchers led by Carnegie Mellon University Professor of Biological Sciences Chien Ho have developed a new method for preparing mesenchymal stem cells (MSCs) that not only leads to the production of more native stem cells, but also labels them with a FDA approved iron-oxide nanoparticle (Ferumoxytol).

T cell gives precise mechanical tugs to detect friends and foes

T cells, the security guards of the immune system, use a kind of mechanical "handshake" to test whether a cell they encounter is a friend or foe, a new study finds.

New nanoparticle approach can deliver antiobesity drugs directly to fat tissue

Researchers at MIT and Brigham and Women's Hospital have developed nanoparticles that can deliver antiobesity drugs directly to fat tissue. Overweight mice treated with these nanoparticles lost 10 percent of their body weight over 25 days, without showing any negative side effects.

ZOTEN nanoparticles can help develop natural immunity against genital herpes

An effective vaccine against the virus that causes genital herpes has evaded researchers for decades. But now, researchers from the University of Illinois at Chicago working with scientists from Germany have shown that zinc-oxide nanoparticles shaped like jacks can prevent the virus from entering cells, and help natural immunity to develop.

Exposure to titanium dioxide nanoparticles increases bacterial infection of HeLa cells

When human cells are exposed to titanium dioxide without the presence of UV light from the sun, the risk for bacterial infection more than doubles. This finding by a Stony Brook University-led research team, published early online in the Journal of Nanobiotechnology, raises concerns about exposure to titanium dioxide, a nanoparticle commonly used in millions of products worldwide ranging from cosmetics to toothpaste, gum, food coloring, and medicines.

Novel nanoparticle drug delivery system for enhanced tumor penetration of cancer drugs

For more than a decade, biomedical researchers have been looking for better ways to deliver cancer-killing medication directly to tumors in the body. Tiny capsules, called nanoparticles, are now being used to transport chemotherapy medicine through the bloodstream, to the doorstep of cancerous tumors.

Researchers develop new technique to study blood vessel inflammation

Nanotechnology has led to better diagnostic techniques and more effective treatments for a variety of illnesses. Tiny devices measuring between 1 and 100 micrometers--one micrometer is equal to one millionth of a meter--enable scientists to observe cell activity and deliver drugs to individual cells--a breakthrough that is on the verge of revolutionizing precision medicine for treatment of diseases such as cancer.

Scientists develop triple-stage 'cluster bomb' system to deliver cisplatin drug through nanoparticles

Scientists have devised a triple-stage "cluster bomb" system for delivering the chemotherapy drug cisplatin, via tiny nanoparticles designed to break up when they reach a tumor.

Researchers demonstrate novel method for imaging engineered nanoparticles in tissues

As a testament to Governor Andrew Cuomo’s leadership in developing an unparalleled research and development ecosystem in New York State, Sara Brenner, MD, MPH and her colleagues at SUNY Polytechnic Institute (SUNY Poly), the George Washington School of Medicine and Health Sciences, and Stony Brook University have demonstrated a novel method for the rapid visualization and identification of engineered nanoparticles in tissues.

Engineered HIV vaccine protein may prevent HIV infection

Some people infected with HIV naturally produce antibodies that effectively neutralize many strains of the rapidly mutating virus, and scientists are working to develop a vaccine capable of inducing such "broadly neutralizing" antibodies that can prevent HIV infection.

Researchers develop unique approach to track, label neural stem cells

An overwhelming number of researchers still struggle within the black hole of the effectiveness and safety of stem cell therapy for neurological diseases. While the complexity of understanding how neurons grow, connect and function has long been studied, it remains a mystery, one that graduate student Forrest Goodfellow in the University of Georgia Regenerative Bioscience Center is helping unravel.

Synthetic nanoparticle can light up and treat atherosclerotic plaques

Atherosclerosis, a disease in which plaque builds up inside arteries, is a prolific and invisible killer, but it may soon lose its ability to hide in the body and wreak havoc. Scientists have now developed a nanoparticle that functionally mimics nature's own high-density lipoprotein (HDL). The nanoparticle can simultaneously light up and treat atherosclerotic plaques that clog arteries. Therapy with this approach could someday help prevent deadly heart attacks and strokes.

Delivering microRNAs in cancer treatment: an interview with Dr Conde and Prof Artzi

microRNAs (miRs) are small endogenous noncoding RNA molecules (20–23 nucleotides) derived from imperfectly paired hairpin RNA structures naturally encoded in the genome that act specifically as triggering molecules to control translational repression or mRNA degradation.

Novel nanoparticle technology can decipher protein structures and help access drug targets

Researchers at Karolinska Institutet, Sweden, have developed a nanoparticle technology that can be used to stabilise membrane proteins so that their structure can be studied in a lipid environment. The method, described in Nature Methods, makes it possible to access drug targets that previously could not be investigated and therefore potentially allows for the development of novel drugs, therapeutic antibodies and vaccines.

Drug-incorporated nanoparticle platforms allow for selective targeting of cancer cells

Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells. It is a leading cause of death and the burden is expected to grow worldwide due to the growth and aging of the population, mainly in less developed countries, in which about 82% of the world's population resides. By 2030, the global burden is expected to grow to 21.7 million new cancer cases and 13 million cancer deaths simply due to the growth and aging of the population. Current cancer therapy approaches are based in surgery, radiotherapy and chemotherapy, being the chemotherapy the one that shows the greater efficiency for cancer treatment, mainly in more advanced stages. A major problem with this conventional chemotherapy is its toxicity and it also destroys healthy tissues resulting in systemic toxicity besides beneficial characteristics of killing cancer cells. Anticancer drugs also destroy healthy tissues resulting in systemic toxicity.
