Improved nanoparticles deliver drugs into brain

The brain is a notoriously difficult organ to treat, but Johns Hopkins researchers report they are one step closer to having a drug-delivery system flexible enough to overcome some key challenges posed by brain cancer and perhaps other maladies affecting that organ.

New study shows promise in using RNA nanotechnology to treat cancers and viral infections

 

A new study by University of Kentucky researchers shows promise for developing ultrastable RNA nanoparticles that may help treat cancer and viral infections by regulating cell function and binding to cancers without harming surrounding tissue.

First-of-its-kind approach nanomedicine design effectively targets cancer with decreased toxicity

 

Researchers at Brigham and Women’s Hospital (BWH) are the first to report a new approach that integrates rational drug design with supramolecular nanochemistry in cancer treatment.

Supramolecular chemistry is the development of complex chemical systems using molecular building blocks. The researchers utilized such methods to create nanoparticles that significantly enhanced antitumor activity with decreased toxicity in breast and ovarian cancer models.

Novel nanotherapeutic delivers clot-busting drugs directly to obstructed blood vessels

 

Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University have developed a novel biomimetic strategy that delivers life-saving nanotherapeutics directly to obstructed blood vessels, dissolving blood clots before they cause serious damage or even death. This new approach enables thrombus dissolution while using only a fraction of the drug dose normally required, thereby minimizing bleeding side effects that currently limit widespread use of clot-busting drugs.

Nanopills release drugs directly from the inside of cells

UAB researchers developed a new vehicle to release proteins with therapeutic effects. The vehicles are known as “bacteria inclusion bodies”, stable insoluble nanoparticles which are found normally in recombinant bacteria. Even though these inclusion bodies traditionally have been an obstacle in the industrial production of soluble enzymes and biodrugs, they were recently recognised to have large amounts of functional proteins with direct values in industrial and biomedical applications.

A realistic look at the promises and perils of nanomedicine

Is the emerging field of nanomedicine a breathtaking technological revolution that promises remarkable new ways of diagnosing and treating diseases? Or does it portend the release of dangerous nanoparticles, nanorobots or nanoelectronic devices that will wreak havoc in the body? A new review of more than 500 studies on the topic concludes that neither scenario is likely. It appears in ACS’ journal Molecular Pharmaceutics.

Innovative vaccines with nanotechnology

European Research Consortium wants to develop novel vaccination against hepatitis C

HCVAX is a European joint project that reaches out to develop a vaccine against hepatitis C based on nanotechnology. The German Helmholtz Centre for Infection Research (Helmholtz-Zentrum für Infektionsforschung, HZI) in Braunschweig and its department “Vaccinology and Applied Microbiology” is now a part of the transnational consortium with researchers from Germany, France and Switzerland.

Hitting target in cancer fight now easier with new nanoparticle platform, UCLA scientists say

The ability to use nanoparticles to deliver payloads of cancer-fighting drugs to tumors in the body could herald a fundamental change in chemotherapy treatment. But scientists are still at a relatively early stage in the implementation of this technology.

Stanford research moves nanomedicine one step closer to reality

STANFORD, Calif. — A class of engineered nanoparticles — gold-centered spheres smaller than viruses — has been shown safe when administered by two alternative routes in a mouse study led by investigators at the Stanford University School of Medicine. This marks the first step up the ladder of toxicology studies that, within a year and a half, could yield to human trials of the tiny agents for detection of colorectal and possibly other cancers.
