Doped Nanocrystals Developed for Bioimaging
SINGAPORE, Nov. 23, 2011 — A synthesis of lanthanide-doped core-shell nanocrystals has resulted in advanced light-control properties for bioimaging applications including cancer diagnostics, medical imaging and therapeutic delivery. A research team from the National...
Stamping technique enables cheaper nanodevices
NASHVILLE, Tenn. – A simple technique for stamping patterns invisible to the human eye onto a special class of nanomaterials provides a new, cost-effective way to produce novel devices for a wide range of applications, including drug delivery, chemical and biological...
Nanotubes Improve Fluorescence Imaging
STANFORD, Calif., June 1, 2011 — An improved imaging method using fluorescent carbon nanotubes allows researchers to see centimeters deep into a mouse with far more clarity than conventional dyes provide. For a creature the size of a mouse, a few centimeters makes a great...
Pantec Laser to Incorporate Oclaro Diode Bars
SAN JOSE, Calif., May 24, 2011 — Oclaro Inc., an optical communications and laser technology supplier, has announced that its 9xx-nm high-power laser diode bars have been selected by Pantec Biosolutions AG for use in its next-generation PLEASE (Precise Laser Epidermal System)...
Optical Fiber Device Promises Safer Drug Delivery
IRVINE, Calif., April 12, 2011 — A new optical fiber-based drug delivery device promises to unlock the potential of photosensitive chemicals to kill drug-resistant infections and perhaps cancer tumors as well. The device was designed and constructed by researchers Jie Chen, Thomas...
Nanosight Used to Study DNA
SALISBURY, England, Nov. 1, 2010 — The Department of Biomedical Engineering at Johns Hopkins University School of Medicine is using the NanoSight LM10-HS, a nanoparticle tracking analysis technique, to study self-assembled polymer/DNA particles for drug delivery. The main...
Laser Light Could Impact Drug Delivery
KINGSTON, Ontario, Oct. 8, 2010 — Researchers at Queen’s University have discovered how molecules in glass or plastic are able to move when exposed to light from a laser. The findings could one day be used to facilitate medicinal drug distribution by allowing doctors to...
Edible Optics, Implantable Electronics
MEDFORD, Mass., Aug. 11, 2010 — A decade of research has yielded new uses for an ancient material – silk fibers. Thanks to their amazing mechanical properties as well as their looks, silk fibers have been important materials in textiles, medical sutures, and even armor for...
MOEMS-MEMS Plenary Talks
SAN FRANCISCO, Jan. 26, 2010 – Various applications of microelectromechanical and micro-opto-electromechanical systems (MEMS and MOEMS, respectively) proved popular at the MOEMS-MEMS subconference’s plenary talk...
QD Core Given Gold Shell
SEATTLE, July 28, 2009 -- Nanoparticles have been developed to perform a wide range of medical uses, from imaging tumors to carrying drugs to delivering pulses of heat to destroy tumor cells. But rather than settling for just one of these, researchers at the University of...
3-D Nanofluidic Devices
GAITHERSBURG, Md., April 1, 2009 – By manufacturing integrated circuits at the nanometer level, a method was devised for creating nanofluidic devices with complex 3-D surfaces.
Particles' Surprising Moves
RALEIGH, N.C., March 3, 2008 -- Microscopic Janus particles -- spheres whose halves are physically or chemically different -- have been found to propel themselves in unexpected ways when an electric field is applied. Researchers at North Carolina State University (NC State) in...
Thin Film Delivers Drugs
CAMBRIDGE, Mass., Feb. 12, 2008 -- An implantable thin-film system can deliver drugs to specific targets in the body by disintegrating when an electric field is applied. The film developed at the Massachusetts Institute of Technology serves as a "micropharmacy" and could...
DNA Controls Nanoparticles
UPTON, N.Y., Aug. 23, 2007 -- DNA, the molecule that carries life’s blueprint, is being used to control the size of nanoparticles and the speed at which they form. Learning how to tailor their assembly could lead to the creation of nanoparticles for more efficient energy...
No Carrier Necessary: This Drug Delivers Itself
BUFFALO, N.Y. March 19, 2007 -- The problem of efficiently delivering drugs, especially those that are hydrophobic -- or water-repellant -- to tumors or other disease sites has long challenged scientists to develop innovative delivery systems that keep these drugs intact until...
Superstable Glass May Aid Drug Delivery
MADISON, Wis., Dec. 8, 2006 -- A new method has been developed for crafting some of the most stable glasses ever formed, materials that are strong and durable like crystal. Its creators hope the superstable glass can one day be used to deliver medicines inside the body. Using...
Nano Chemists Make Curved Structures
Jan 30, 2004 — EVANSTON, Ill., Jan. 29 --- The natural world is full of curves and three dimensions, but the ability to deliberately and rationally construct such complex structures using nanoscale building blocks has eluded nanotechnologists who are eager to add...
