BIO-OPTICS WORLD, July 2008 ARTICLESBio-Optics World is a bi-monthly magazine that provides news, analysis and explanation of applications involving lasers, optics and imaging systems in the life sciences. The magazine is dedicated to giving readers a firsthand look at cutting-edge research related to the design, development and utilization of optical technologies in the study, diagnosis and treatment of disease and disease processes. Bio-Optics World is available by FREE subscription as an electronic (PDF) download. Subscribers must log in to download electronic issues. Table of ContentsFeaturesBiomedical LasersA new laser-based treatment for psoriasis and vitiligo leaves unaffected skin unexposed—and breaks ground for severe cases.
Optics & ImagingThe optics you choose greatly influence the results you get when using fluorescence for biological applications.
Traditional methods of comparing complex images are limited. A new approach increases treatment efficacy—and saves clinical time and costs.
Feature FocusA new approach enables researchers to study cells directly within thick tissues and even entire organs— and thus retain vital contextual information.
It used to be, in flow cytometry, that low cost meant low resolution and compromised sensitivity.
DepartmentsBioOptics BreakthroughsNews & ViewsA research team at Osaka University in Japan has shown that cultured heart-muscle cells synchronize their contractions in response to pulses from a femtosecond laser.
An adaptation of a laser procedure developed to treat noncancerous abnormalities on the vocal cords has found preliminary success in treating cancerous tumors of the cords.
Determining the existence of cancer in biopsied tissue presents a major problem to clinics and hospitals, particularly those in locations that lack on-site pathologists.
Lasering USA (San Ramon, CA) knows it is a little fish in a big pond when it comes to the skin rejuvenation market, but the company is confident that its technology—originally developed in Italy—will set it apart.
Lumencor (Beaverton, OR), a year-old company focused on the development of novel light engines, is targeting life-science instrumentation with its initial products and is gearing up to move from prototype phase to volume manufacturing by the fourth quarter of 2008.
Biomedical scientists at University of Texas (UT) Southwestern Medical Center and nanotechnology researchers from UT Dallas are testing a new way to kill cancer cells selectively by using a trio of tools: antibodies, nanotubes, and light.
In the minimally invasive treatment of photodynamic therapy (PDT), photosensitive drugs first attach themselves preferentially to malignant tumors in the body and then set out to destroy the tumors in response to illumination by specific wavelengths of laser light.
PioneersIn his unassuming way, Bill Telford has pushed the capabilities and impact of flow cytometry—influencing the progress of both people and instrumentation.
End ResultColumnsEditorialOptical coherence tomography (OCT), the noninvasive, noncontact, and radiation-safe micron-scale imaging technique that has been commercialized only recently, is hot—in terms of both interest and development.
In the LoopAny company with a medical device, novel therapeutic technique or diagnostic product knows too well that a key hurdle to getting that product to market is approval by the U.S. Food and Drug Administration (FDA).
Inside InstrumentationWhen removing a tumor, a surgeon can’t always distinguish cancerous tissue from healthy tissue.
