Chemist to develop inkjet-printed, nanoparticle-based test strips to detect disease-causing bacteria in drinking water

Today the National Academy of Sciences announced a three-year, $271,930 grant to chemist Vincent Rotello at the University of Massachusetts Amherst to develop, test and deploy new, sensitive, reliable and affordable inkjet-printed, nanoparticle-based test strips for detecting disease-causing bacteria in drinking water, with researchers at the Lahore University of Management Sciences (LUMS), Pakistan.

Biomolecular interactions of nanoparticles can improve drug development, optical sensors and more

In chemical reactions, left and right can make a big difference. A "left-handed" molecule of a particular chemical composition could be an effective drug, while its mirror-image "right-handed" counterpart could be completely inactive.

Researchers develop new drug delivery systems to treat cancer by blocking signaling receptor

A cardiac hormone signaling receptor abundantly expressed both in inflamed tissues and cancers appears to recruit stem cells that form the blood vessels needed to feed tumor growth, reports a new study by scientists at the University of South Florida Nanomedicine Research Center.

Case Comprehensive Cancer Center secures "outstanding" rating from NCI

The Case Comprehensive Cancer Center (CCCC) again demonstrated the compelling power of partnership in securing an overall rating of "outstanding" and a five-year renewal of its grant from the National Cancer Institute (NCI).

Study shows "bioadhesive" coating can increase intestinal uptake of protein-based drugs

For protein-based drugs such as insulin to be taken orally rather than injected, bioengineers need to find a way to shuttle them safely through the stomach to the small intestine where they can be absorbed and distributed by the bloodstream.

Ingestion of nanoparticles at typical environmental levels unlikely to cause overt toxicity

Ingestion of commonly encountered nanoparticles at typical environmental levels is unlikely to cause overt toxicity, according to US researchers. Nevertheless there is insufficient evidence to determine whether chronic exposures could lead to subtle alterations in intestinal immune function, protein profiles, or microbial balance.

Study suggests new ways to maximize delivery of RNA strands

Nanoparticles that deliver short strands of RNA offer a way to treat cancer and other diseases by shutting off malfunctioning genes. Although this approach has shown some promise, scientists are still not sure exactly what happens to the nanoparticles once they get inside their target cells.

Bioapplications of nanoparticles: an interview with Dr Catherine Berry, University of Glasgow

These particles are all classed as inorganic particles, which can all be utilised in biomedical applications. They differ in terms of their inherent material and size dependent physiochemical properties, for example, their optical and magnetic properties.

Researchers develop nano-volcanoes that hold promise for new drug-delivery technologies

Researchers from North Carolina State University have developed a method for creating "nano-volcanoes" by shining various colors of light through a nanoscale "crystal ball" made of a synthetic polymer.

Smartphone users can now diagnose diabetes or lung cancer quickly and effectively by simply breathing

Today's technological innovation enables smartphone users to diagnose serious diseases such as diabetes or lung cancer quickly and effectively by simply breathing into a small gadget, a nanofiber breathing sensor, mounted on the phones.

New plug-in optical sensor can help diagnose Kaposi's sarcoma

As antiretroviral drugs that treat HIV have become more commonplace, the incidence of Kaposi's sarcoma, a type of cancer linked to AIDS, has decreased in the United States.

New technique selectively represses unwanted immune reactions without disabling immune system

The human immune system is remarkably efficient, but sometimes its attack is misdirected, leading to allergies, autoimmune diseases and rejection of transplant organs and therapeutic drugs. Current immune suppressants have major drawbacks, but a team from The Scripps Research Institute (TSRI) has demonstrated a new technique that may lead to a better way to selectively repress unwanted immune reactions without disabling the immune system as a whole.

Nanoparticle-based immunotherapy for cancer

The German Research Foundation has established a new Collaborative Research Center on "Nanodimensional polymer therapeutics for tumor therapy" (CRC 1066) at Johannes Gutenberg University Mainz and the Max Planck Institute for Polymer Research (MPI-P).

New nanoparticle gene delivery method to prevent stenting procedure complications

Stent angioplasty saves lives, but there often are side effects and complications related to the procedure, such as arterial restenosis and thrombosis. In the June 2013 issue of The FASEB Journal, however, scientists report that they have discovered a new nanoparticle gene delivery method that may overcome current limitations of gene therapy vectors and prevent complications associated with the stenting procedure.

Viral load: A new technique that helps doctors diagnose chronic viral diseases

To test the severity of a viral infection, clinicians try to gauge how many viruses are packed into a certain volume of blood or other bodily fluid. This measurement, called viral load, helps doctors diagnose or monitor chronic viral diseases such as HIV/AIDS and hepatitis.

University of Strathclyde uses new imaging technique to track nanomedicines' effects on patients

A pioneering imaging technique to track the effects of next-generation nanomedicines on patients has been harnessed by a University of Strathclyde academic.

Spherical nanoparticles transform into netlike structures at site of cancer

Scientists at the University of California, San Diego, have designed tiny spherical particles to float easily through the bloodstream after injection, then assemble into a durable scaffold within diseased tissue. An enzyme produced by a specific type of tumor can trigger the transformation of the spheres into netlike structures that accumulate at the site of a cancer, the team reports in the journal Advanced Materials this week.

New drug delivery system can help treat lung cancer

Researchers have developed a new drug delivery system that allows inhalation of chemotherapeutic drugs to help treat lung cancer, and in laboratory and animal tests it appears to reduce the systemic damage done to other organs while significantly improving the treatment of lung tumors.

Scientists make important step forward in the quest to develop universal influenza vaccine

A new approach for immunizing against influenza elicited a more potent immune response and broader protection than the currently licensed seasonal influenza vaccines when tested in mice and ferrets.
