MRI contrast agent turns on at sites of disease

MRI contrast agent turns on at sites of disease
  At the Institute for Basic Science (IBS) in South Korea, researchers have developed a type of MRI contrast agent that only lights up when near a target. It consists of two components, an “enhancer” which is the actual contrast agent that lights up and a “quencher” that controls the activation of the enhancer.

DNA “barcoding” aids therapeutic delivery

DNA “barcoding” aids therapeutic delivery
Using tiny snippets of DNA as “barcodes,” researchers have developed a new technique for rapidly screening the ability of nanoparticles to selectively deliver therapeutic genes to specific organs of the body. The technique could accelerate the development and use of gene therapies for such killers as heart disease, cancer and Parkinson’s disease. Genetic therapies, such as those made from DNA or RNA, are hard to deliver into the right cells in the body.

Nanoparticle screen could speed up drug development

Nanoparticle screen could speed up drug development
  Many scientists are pursuing ways to treat disease by delivering DNA or RNA that can turn a gene on or off. However, a major obstacle to progress in this field has been finding ways to safely deliver that genetic material to the correct cells. Encapsulating strands of RNA or DNA in tiny particles is one promising approach.

Nanotechnology for hyperthermic cancer therapy

Nanotechnology for hyperthermic cancer therapy
Healthcare is the area where nanotechnology could bring revolutionary improvements. A European project investigated the possibility of nanotechnology applications for hyperthermic cancer therapy. Therapeutic applications based on metallic and magnetic nanoparticles already have prominent place in the development of anticancer nanotherapy. These nanoparticles generate heat, destroying cancer cells without damaging healthy tissues when excited by a remote energy source.

Nanoscience and magnetism create faster medical tests

Nanoscience and magnetism create faster medical tests
  A UCF researcher has combined cutting-edge nanoscience with a magnetic phenomenon discovered more than 170 years ago to create a method for speedy medical tests. The discovery, if commercialised, could lead to faster test results for HIV, Lyme disease, syphilis, rotavirus and other infectious conditions.

Nanoparticles for drug delivery into the skin

Nanoparticles for drug delivery into the skin
Nanoparticles have emerged as important vehicles in drug delivery. Understanding the relationship between their structure and efficiency is central for maximising skin permeation. Systemic drug delivery often takes place through the skin due to its ease of use and better patient compliance. However, the outermost layer of the skin, the stratum corneum (SC) poses a significant barrier to drug application.

Researchers develop wound-healing technology

Researchers develop wound-healing technology
  A WSU research team has successfully used a mild electric current to take on and beat drug-resistant bacterial infections, a technology that may eventually be used to treat chronic wound infections. The researchers report on their work in the online edition of npj Biofilms and Microbiomes.

Nanoscale factories built to order

Nanoscale factories built to order
Performing chemical reactions inside tiny droplets can help manufacturers develop greener processes for coating drugs. A discovery led by Singapore's Agency for Science, Technology and Research (A*STAR) could lead to improvements in the way drugs are delivered to the right parts of the body by uncovering the mechanisms that help oil, water, and free radicals mix in tiny droplets.

'Nanobottles' offer blueprint for enhanced biological imaging

'Nanobottles' offer blueprint for enhanced biological imaging
A pan-European team of researchers involving the University of Oxford has developed a new technique to provide cellular 'blueprints' that could help scientists interpret the results of X-ray fluorescence (XRF) mapping. XRF imaging is used for a wide range of elemental analyses and has a number of medicine-based potential applications, including tracking and understanding diseases such as Alzheimer's, and the evaluation of heavy metal poisoning.
