Bneficial Ions Released from Bioactive Glass

Bioactive glass, used as a synthetic bone grafting material, can act as a vehicle for delivering ions beneficial for healing. Silica has been shown to regulate cells and improve bone growth and differentiation. Calcium released from the glass will react with phosphate ions present in the body fluids and deposit a nanocrystalline HA on the glass surface at a neutral to basic local pH.

			Improving Image Resolution Using Nanoparticles Nanoparticles are small sized particles capable of penetrating vasculature and circulating the body. Since their development, they have been applied to imaging as a way of tagging specific areas of the body or tissue, including in magnetic resonance imaging (MRI), optical imaging, and even ultrasound imaging.

			Plasmonics in Biology and Nanomedicine Plasma is one of the fundamental states of matter that is generated when a neutral gas is heated or subjected to a strong electromagnetic field, both of which can result in the breaking of bonds and the stripping of electrons from atomic nuclei.

	Using X-ray-nanoparticle interactions for improved radiation therapy Radiation therapy is a time-honored approach to destroying cancer cells that escape the knife, or which are not accessible for surgery. However, it has its risks and limitations. Now a new study, published in the journal Scientific Reports, indicates a promising new way to deliver locally aggressive radiation therapy in cancer, using the element gadolinium.

	Celiac disease may now be curable with biodegradable nanoparticles A phase 2 trial just concluded shows that people with celiac disease may now be able to hope for a cure, through a treatment that makes the immune system tolerant towards gluten. This could eventually make it possible for such individuals to eat gluten-containing foods without fear.

	New encapsulation technology could improve drug delivery Researchers have developed a faster, cheaper way to coat liquid medication, an invention that could improve how drugs are delivered in the body. The new encapsulation technology, developed by engineers at the University of Waterloo, uses gravity and other natural forces to wrap drops as they fall through a thin layer of liquid shell floating on a base liquid.

	Nanoparticles moving through airway mucus may predict severity of COPD In a proof-of-concept experiment, researchers from Johns Hopkins Medicine say they have successfully used microscopic man-made particles to predict the severity of patients' chronic obstructive pulmonary disease by measuring how quickly the particles move through mucus samples.
