For the first time, investigating the heart as a whole In light of the increasing demand for artificial nanoparticles in medicine and industry, it is important for manufacturers to understand just how these particles influence bodily functions and which mechanisms are at play "“ questions to which there has been a dearth of knowledge. Studies on heart patients have shown for decades that particulate matter has a negative effect on the cardiovascular system. Yet, it remained unclear...

Nanobodies produced by camels have unique properties, which can be used in future drug development. New research published in the Journal of Controlled Release confirms that nanobodies can help scientists in the fight against cancer. Members of the camelid family have particular heavy-chain antibodies in their blood known as nanobodies, that may serve as therapeutic proteins. One of the most powerful advantages of nanobodies is that they can be easily attached to other proteins and...

Tiny fibres used to strengthen items such as bike frames and hockey sticks could pose risks to workers who make them. Certain types of carbon nanotubes - cylindrical molecules about one-thousandth of the width of a human hair - could cause cancer in the lining of the lung, University research shows. The study in mice found short carbon nanotubes appear relatively harmless if they entered lung cavities. However, longer nanotubes were more likely to get stuck there and ultimately cause a type...

Depending on whom you ask, nanoparticles are, potentially, either one of the most promising or the most perilous creations of science. These tiny objects can deliver drugs efficiently and enhance the properties of many materials, but what if they also are hazardous to your health in some way? Now, scientists at the National Institute of Standards and Technology (NIST) have found* a way to manipulate nanoparticles so that questions like this can be answered. The team has developed a method of...

Researchers are able to produce medicine encapsulated in nanoparticles the size of viruses, but new research has shown another great challenge in nanomedicine "“ the immune system "“ and the importance of the coating polymers on the nanoparticle surface. Researchers have over time been able to show that medicine designed at nanoscale offers unprecedented opportunities for targeted treatment of serious diseases such as cancer. However, now research also shows that the body's immune...

New study examines nanoparticles' effects on plants Using particles that are 1/100,000 the width of a human hair to deliver drugs to cells or assist plants in fighting off pests may sound like something out of a science fiction movie, but these scenarios may be a common occurrence in the near future. Carbon nanotubes, cylindrically shaped carbon molecules with a diameter of about 1 nanometer, have many potential applications in a variety of fields, such as biomedical engineering and medical...

Researchers at North Carolina State University have developed a method for predicting the ways nanoparticles will interact with biological systems "“ including the human body. Their work could have implications for improved human and environmental safety in the handling of nanomaterials, as well as applications for drug delivery. NC State researchers Dr. Jim Riviere, Burroughs Wellcome Distinguished Professor of Pharmacology and director of the university's Center for Chemical...

Drug delivery technique Using chemical "nanoblasts" that punch tiny holes in the protective membranes of cells, researchers have demonstrated a new technique for getting therapeutic small molecules, proteins and DNA directly into living cells. Carbon nanoparticles activated by bursts of laser light trigger the tiny blasts, which open holes in cell membranes just long enough to admit therapeutic agents contained in the surrounding fluid. By adjusting laser exposure, the researchers...


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
