By using drug delivery vehicles, so-called nanocarriers, pharmaceuticals reach the diseased area in the body. There they accelerate the healing process. But in order to prevent them from getting ingested by phagocytes, the surfaces of the nanocarriers are typically coated with the biocompatible synthetic polymer poly(ethylene glycol) (PEG). Scientists at the Mainz University Medical Center and…
Vanderbilt University Medical Center nephrologist and associate professor of medicine Dr. William H. Fissell IV, is making major progress on a first-of-its kind device to free kidney patients from dialysis. He is building an implantable artificial kidney with microchip filters and living kidney cells that will be powered by a patient’s own heart.
Multiple sclerosis (MS) may be triggered by the death of brain cells that make the insulation around nerve fibers, a surprising new view of the disease reported in a study from Northwestern Medicine and The University of Chicago.
Iron nanoparticles injected before magnetic resonance imaging can make tissues more visible and the same nanoparticles may allow doctors to precisely target tumors with new medicines. However, among the challenges to the practical use of nanoparticles in the human body is what scientists refer to as lack of “hemocompatibility” – nanoparticles tend to be attacked and cleared by the immune…
Northwestern University scientists have developed the first liquid nanoscale laser. And it’s tunable in real time, meaning you can quickly and simply produce different colors, a unique and useful feature. The laser technology could lead to practical applications, such as a new form of a “lab on a chip” for medical diagnostics.
Vaccination remains one of the most efficient strategies against infectious diseases, often being the best protection against infections such as hepatitis B, or influenza. European Hospital reports on expert reviews of vaccines in the pipeline and the potential of nanomedicine given during the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC) annual meeting in…
Scientists have designed nanoparticles that release drugs in the presence of a class of proteins that enable cancers to metastasize. That is, they have engineered a drug delivery system so that the very enzymes that make cancers dangerous could instead guide their destruction.
Autografts, the gold standard of bone grafts, have several limitations. As a result, new orthobiologics products are being developed for the benefit of patients as well as surgeons. Innovations in biomaterials and graft design have enabled these advanced products that mimic the natural human bone and speed up bone repair and regeneration.
Clinical trials are under way at two NHS hospitals in England to assess breathalyser technology to detect lung cancer. Phase I clinical trials of a diagnostic breathalyser developed by Cambridge-based Owlstone Ltd have shown accurate identification of 12 lung cancer biomarkers in breath specimens. A Phase II trial is now targeting development of a small, handheld device that can be used in GP…
Newly released images revealing the ‘bicycle spoke’ structure of a heart cell may hold key clues to reducing damage from a heart attack.
Scientists in the UK have designed a new self-assembling nanoparticle that targets tumours and could lead to quicker diagnosis of cancer. Researchers at Imperial College London report that a new self-assembling nanoparticle can adhere to cancer cells, thus making them visible in MRI scans and possibly eliminate the need for invasive tissue biopsies.

Nanoparticles are extremely small particles that can be modified for a variety of uses in the medical field. For example, nanoparticles can be engineered to be able to transport medicines specifically to the disease site while not interfering with healthy body parts.
imec, the European research centre for nanoelectronics, has linked with Johns Hopkins University in Baltimore, USA, to develop the next generation of highly miniaturised medical tools.
