Visible-Light-Activated Prodrug Can Combat Chemo’s Side Effects
HONG KONG, Oct. 4, 2019 — Many antitumor drugs used in chemotherapy move around in the patient’s blood after intake. Healthy cells may be killed along with tumor cells, causing undesirable side effects. To avert potential “collateral damage” caused by antitumor drugs, a research team at City University of Hong Kong (CityU) has developed a small-molecule platinum(IV) anticancer prodrug called phorbiplatin. Phorbiplatin is shown to be inert in the dark, but it can be controllably activated under low-power red-light...
Murugkar Wins Norman Edmund Inspiration Award
BARRINGTON, N.J., Nov. 17, 2016 — Optics and imaging developer Edmund Optics Inc. has awarded Dr. Sangeeta Murugkar, assistant professor at Carleton University in Ottawa, Canada, the 2016 Norman Edmund Inspiration Award for his development of a handheld probe for the noninvasive, in...
Nanoballoons and Lasers: A New Cancer Fighter
BUFFALO, N.Y., April 3, 2014 — Chemotherapeutic drugs have long held their own in the fight against cancer, but inefficiency in delivery and unwanted side effects continue to hinder the process.
Photoacoustic Imaging Moves into Clinic
ST. LOUIS, March 26, 2012 — Photoacoustic tomography, which combines the best qualities of ultrasound and light absorption, can now provide clinicians with multicontrast images of biological tissue several inches below the skin’s surface.
Laser-based Technique Diagnoses Melanoma
DURHAM, N.C., Feb. 23, 2011 — High-resolution images from a laser-based tool developed at Duke University could help doctors better diagnose melanoma, the deadliest form of skin cancer. The improved diagnoses could potentially save thousands of lives and millions of dollars in...
Quantum Dots: Applications for Artificial Atoms Expanding
Feb 23, 2011 — The use of quantum dots is nearly ubiquitous in Förster’s resonance energy transfer (FRET), but scientists are just beginning to scratch the surface on other applications for the semiconductor nanocrystals, such as in biosensors and as a way...
Plasmonic Nanobubbles Kill Cancer Cells
HOUSTON, Oct. 7, 2010 — Plasmonic Nanobubbles Kill Cancer Cells HOUSTON, Oct. 6, 2010 — Rice Plasmonic nanobubbles, generated around gold nanoparticles with a laser pulse, can detect and destroy cancer cells in vivo by creating tiny, shiny vapor bubbles that reveal...
'Drops' of Gold Burn Tumors
BARCELONA, Spain, July 21, 2009 – French researcher Romain Quidant proposes applying laser light to gold nanoparticles inserted into tumor cells, heating the particles to such a degree that the damaged cells would be completely burnt.
Imaging the Upshot of Chemo
LOS ANGELES, April 15, 2009 – Oncologists can now assess the effectiveness of chemotherapy in about a week, a process that typically takes months. The noninvasive method combines PET and CT scanning to image the tumor's metabolic function and quickly determine if the toxic drugs...
Light Spots Cellular Suicide
DURHAM, N.C., Feb. 2, 2009 – Bioengineers now are using scattered light to help determine whether cancer cells are responding to chemotherapy. The new technology, developed by bioengineers at Duke University, is helping clinicians more precisely detect within a matter of hours...

Unidym Forms Bioscience Unit
MENLO PARK, Calif., Mar. 21, 2008 -- Carbon nanotube maker Unidym Inc. announced this week it has formed a spinoff, Ensysce Biosciences Inc., that will focus on research into medical applications of carbon nanotubes. Unidym, a majority-owned subsidiary of Arrowhead Research Corp.,...
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...
