Quantum Dot Corporation Announces Scientific Publication Demonstrating the Detection of Breast Cancer Markers
Hayward, CA. December 2nd, 2002
Quantum Dot Corporation (QDC), the
leader in Qdot(tm) biotechnology applications and products, announced
today the publication of a seminal scientific paper in the prestigious
journal Nature Biotechnology. The paper, entitled "Immunofluorescent
labeling of cancer marker Her2 and other cellular targets with
semiconductor quantum dots", was published in the on-line version of
Nature Biotechnology, following collaborative work performed by
scientists at Genentech and QDC. The print version will be published in
January 2003.
"The promise of Qdot conjugates to revolutionize biological detection
has now become a reality. Our work with Genentech is the first
practical application of the Qdot technology in an important biological
system - specific detection of breast cancer markers. These results
demonstrate the dramatic sensitivity and stability benefits enabled
using Qdot detection," said Xingyong Wu, Ph.D., senior staff scientist
at QDC, and the lead author of the paper. "We have also demonstrated
cancer marker detection in live cancer cells, an extremely difficult
task using conventional methods," continued Dr. Wu.
"This work demonstrates how Qdot technology allows the detection of
many biological analytes simultaneously, using a range of different
colored Qdot nanocrystals," stated Charlie Hotz, Ph.D., director of
chemistry at QDC. "This range of colors is achieved using different
sized nanocrystals. Our unique ability to precisely tune the size of
these nanoscale structures, at tolerances below one nanometer, is
critical," continued Dr. Hotz.
"Coming so rapidly on the heels of our first product launch last month,
this work is a strong validation of the commercial value of the Qdot
technology," said Carol C. Lou, QDC's President and Chief Operations
Officer. "We highly value the relationship with our colleagues at
Genentech, and we look forward to working with them on further
innovative applications of our products."
Qdot(tm) nanocrystals, or quantum dots, are nanometer sized
semiconductor crystals that brightly light up specific biological
events. These nano-scale molecular light emitting diodes (LEDs) allow
rapid, parallel, and ultra-sensitive detection of biomolecular
interactions.
Founded in 1998, Quantum Dot Corporation is located in Hayward, CA. The
company and its advisors are the world's leading experts in
semiconductor nanocrystal (Qdot(tm)) technology and its applications.
QDC sells and markets products to life science researchers worldwide,
and is seeking marketing partners for its diagnostic applications.
