Nano Bullets for Ovarian Cancer
A nano-sized drug capsule designed to seek-and-destroy malignant cells shows signs of being able to significantly shrink ovarian cancer tumors. The researchers behind the novel drug, Mansoor Amiji at Northeastern University and MIT's Robert Langer, say the secret is in the packaging: a pH-sensitive nanoparticle that encapsulates the therapeutics, delivering them directly to cancer sites in mice and suppressing tumor growth. The researchers reported their success in the journal Cancer Chemotherapy and Pharmacology.
Polymers show promise for lab-on-a-chip technology
Researchers are touting the use of liquid crystalline polymers (LCP) as a viable tool for use in devices such as the sought-after lab-on-a-chip technology.
Hair-thin heart sensor holds promise
San Antonio researchers are beginning work on a sensor finer than the width of a human hair that could be implanted within the hearts of heart failure patients, allowing doctors to monitor them at home.
Vitamin E nanotech innovation marks a big step for formulators
The rejuvenating qualities of vitamin E mean it is has long been a popular choice for anti-ageing skin care products, but likewise, it has traditionally been a difficult compound for formulators to work with. Until now that is.
Nanotubes Trigger Neurons
Researchers at Stanford University have used electrodes made of bundles of multiwalled carbon nanotubes to stimulate rat neurons. In a Nano Letters paper published online this week, the researchers describe making arrays of the 50-micrometer electrodes on a silicon substrate and growing the neurons on the arrays. The neurons responded consistently to the electrical signals from the electrodes.
Ethics and Nanomedicine – Analysis Of The Issues and Principles To Be Faced By The Medical Application of Nanotechnology
The ageing population, the high expectations for better quality of life and the changing lifestyle of European society call for improved, more efficient and affordable health care.
Nanotechnology can offer impressive resolutions, when applied to medical challenges like cancer, diabetes, Parkinson's or Alzheimer's disease, cardiovascular problems, inflammatory or infectious diseases.
Experts of the highest level from industry, research centers and academia convened to prepare the present vision regarding future research priorities in NanoMedicine.
Nanoparticle Design Influences Inflammatory Potential in Lung
Researchers from the University of Giessen in Germany have conducted a study of the inflammatory effects of biodegradable and non-biodegradable nanoparticles on the lungs and found that those made of biodegradable materials did not cause inflammation.
Dual-Mode Nanoscale Imaging Yields New Details of Cellular Events
Investigators from the Georgia Institute of Technology appear to have solved a diagnostic problem with a new nanoscale probe, the Scanning Mass Spectrometry (SMS) probe, that can capture both the biochemical makeup and topography of complex biological objects in their normal environment. This research was originally published in the journal IEE Electronics Letters.
Study Tracks Magnetic Nanoparticles Targeting Breast Tumors
An in-depth study of nanoparticle distribution in tumor-bearing mice has shown that targeted magnetic nanoparticles accumulate and cluster in both primary breast tumors and metastatic lesions that have developed in the lung. These results suggest that targeted magnetic nanoparticles should be useful in both detecting and treating metastatic breast cancer...
Nanoparticles Boost Shape-Memory Effect
Researchers at the Institute of Polymer Research in Germany and DKI German Institute for Polymers have incorporated magnetic nanoparticles in thermoplastic polymers to create shape-memory materials. Applying a magnetic field to a temporarily deformed piece of the material causes it to change back to its original shape, a phenomenon that could be exploited in medical applications.
Dog Virus Nanoparticles Adapted for Tumor Targeting
Empty virus particles have shown promise as potential nanoscale drug carriers that can be modified chemically to display tumor-targeting molecules. Now, investigators at The Scripps Research Institute have shown that canine parvovirus nanoparticles, which bind to a receptor that is overproduced by some types of malignant cells, will naturally target tumors.
