"Drops" of gold that burn tumors

At a technical breakfast, Romain Quidant presented his research into the detection and treatment of cancer using gold nanoparticles illuminated with laser light. Quidant, who was recently awarded the Fresnel Prize 2009 that recognizes the highest level of excellence amongst emerging researchers in the field of photonics, is an ICREA researcher at the UPC's Institute of Photonic Sciences (ICFO) and a fellow of the Cellex Foundation Barcelona.

Overcoming the big ‘nanotech’ challenges

Whether in the fields of medicine, sustainable energy supply or environmental protection, without making use of nanotechnology we will not be capable of overcoming the challenges which the future presents. In parallel with these efforts, though, it is essential that we examine the new technology very carefully for potential risks, such as those presented by free nanoparticles.

Expanding quantum dot utility in cancer diagnosis and treatment

Quantum dots (QDs), nanoparticles that shine with extraordinary brightness when excited by light energy, have shown promise as new tools for detecting cancer at its earliest appearance, but concerns about potential toxicities have limited their clinical development. Researchers at the University of Buffalo may have found an answer to this limitation with their development of a new way to create QDs.

Carbon nanotubes continue to show promise in battle against cancer

Carbon nanotubes, one of the original engineered nanomaterials, also may prove to be among the most versatile, as numerous teams of investigators continue to develop novel nanotube-based therapeutic and diagnostic tools. Over the past month, three new research papers have highlighted the potential of nanotubes as weapons against cancer.

Nanoparticle-mediated targeting of MAPK signaling predisposes tumor to chemotherapy

An interdisciplinary team of researchers at Brigham and Women's Hospital and the Harvard-Massachusetts Institute of Technology (MIT) Division of Health Sciences and Technology has demonstrated a better way to deliver cancer drugs directly to tumors.

Harnessing nanoparticles to track cancer cell changes

The more dots there are, the more accurate a picture you get when you connect them. Cancer researchers adopting that philosophy have developed a new imaging technology that could give scientists the ability to simultaneously measure as many as 100 or more distinct features in or on a single cell. In a disease such as cancer, that capability would provide a much better picture of what is going on in individual tumor cells.

Early detection of pancreatic cancer closer thanks to multifunctional nanoparticles

Pancreatic cancer has a devastatingly low survival rate (less than 5 percent after 5 years) because it is usually diagnosed at an advanced stage. The initial symptoms, such as pain, jaundice, or weight loss, often do not allow the disease to be caught early enough for surgery and chemotherapy to be effective.

Computer-guided nanoparticle therapy destroys tumors

Gold nanoshells are among the most promising new nanoscale therapeutics being developed to kill tumors, acting as antennas that turn light energy into heat that cooks cancer to death. Now, a multi-institutional research team has shown that polymer-coated gold nanorods one-up their spherical counterparts, with a single dose completely destroying all tumors in a nonhuman animal model of human cancer.

New protein stabilisation technique could revolutionise therapeutic drug discovery

A revolutionary new protein stabilisation technique has been developed by scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) which could lead to 30 per cent more proteins being available as potential targets for drug development - opening up exciting possibilities in drug discovery.

Electrothermally driven micropumps for medicine

In biomedicine and biotechnology the smallest, complex, compound sample quantities must be reliably processed. Microsystems with new mechanisms of action for pumping, filtering and separating will manage this task with great efficiency in the future.

Aerosol delivery of antibiotics via nanoparticles

Aerosol delivery of antibiotics via nanoparticles may provide a means to improve drug delivery and increase patient compliance, thus reducing the severity of individual illnesses, the spread of epidemics, and possibly even retarding antibiotic resistance.

Nanodiamonds for drug delivery

A research team at Northwestern University has demonstrated a tool that can precisely deliver tiny doses of drug-carrying nanomaterials to individual cells.

New device could track tumor's growth

Surgical removal of a tissue sample is now the standard for diagnosing cancer. Such procedures, known as biopsies, are accurate but only offer a snapshot of the tumor at a single moment in time.

Tiny gold particles home in on tumors

It has long been known that heat is an effective weapon against tumor cells. However, it's difficult to heat patients' tumors without damaging nearby tissues.

New kind of treatment for sexually transmitted diseases

Yale researchers describe a breakthrough in safe and effective administration of potential antiviral drugs - small interfering RNA (siRNA) molecules that silence genes - the first step in development of a new kind of treatment for sexually transmitted diseases (STDs). The work is reported May 4 as an advance online publication of Nature Materials.
