BioPhotonics News
Building protein microstructures with less expensive lasers
May 1, 2006 — The emission from a femtosecond Ti:sapphire laser can be used to create miniature structures made of protein that fence in a living bacterium. Fabricating structures in this way could someday be used to engineer neuronal networks for prosthetics or in other applications because the method is biofriendly and can be performed in the presence of living cells. Although the structures are small and inexpensive, a femtosecond Ti:sapphire laser costs upward of $100,000 and isn’t the type of...
Camera Phones Emerge as a Health Care Tool
May 1, 2006 — Telemedicine gives patients access to a doctor no matter where they are. Whether a patient uses monitoring equipment to send information to the doctor’s office or an x-ray technician transmits images to a radiologist for examination,...
Creating Clarity: Adaptive Optics for Bioimaging
May 1, 2006 — Biological imaging instruments often have resolution limitations that restrict the ability of researchers and clinicians to detect critical detail. One reason is that, as light passes through tissue to reach the object of interest — a cell,...
Cynosure Inc.
May 1, 2006 — Cynosure Inc. of Westford, Mass., has received FDA approval for its pulse dye laser for the treatment of pigmented lesions, including freckles, solar lentigines, café au lait birthmarks, scars and warts. The 585-nm laser is offered in the...
Diamond biosensors are forever
May 1, 2006 — To make effective biosensors, the detection molecules must be attached to a microelectronics-compatible surface in such a way that it is highly stable for long periods. Combinations of biomolecules and commonly used substrate materials such as...
Engineering and Physical Sciences Research Council
May 1, 2006 — The Engineering and Physical Sciences Research Council of Swindon, UK, and Philips Research of Best, the Netherlands, have formed an alliance to fund research and training in biomedical diagnostic technologies. The four-year joint research framework...
Exploring the evolution of sight
May 1, 2006 — Lizards and several other lower vertebrates have a third, or parietal, eye. Whereas their other two eyes provide high-level visual functions such as image processing, this evolutionary vestige essentially tells time. At dawn, the composition of...
Finally, a transgenic GFP Hydra
May 1, 2006 — Hydra freshwater polyps are important model organisms in environmental and conservation science and evolutionary developmental biology. Scientists study the organisms because they evolved ∋600 million years ago, they can fully generate lost body...
Fluid sensors
May 1, 2006 — A literature package titled “Fluid Sensors for Medical OEMs” from Gems Sensors & Controls Inc. describes the company’s compact liquid level switches, flow and pressure sensors, and electro-optic single-point level sensors for...
Fluorescence lifetime shows temperatures of flowing liquids
May 1, 2006 — Many biological analytical processes would benefit from miniaturization, but some —such as DNA amplification through polymerase chain reaction (PCR) — depend on homogeneous temperature gradients to optimize the chemical or molecular...
Fluorescence technique detects diseases in blood
May 1, 2006 — Doctors can screen for infectious agents or diseases by looking for the presence of marker proteins. Immunological assays are often used for this, but they cannot detect a marker protein unless a certain amount of it is present in a blood sample....
Focusing on the Experiment
May 1, 2006 — For Alexey Khodjakov, a researcher at the New York State Department of Health’s Wadsworth Center in Albany, it wasn’t a question of if but when he would lose focus. Following cells as each divided into many, he and colleagues in his lab...
Fuji Photo Film Co. Ltd.
May 1, 2006 — Fuji Photo Film Co. Ltd. has invested $8.3 million in Perseus Proteomics Inc. Together, the Tokyo-based companies will focus on developing a medical material by combining Fuji’s proprietary materials with an imaging technique that enables...
Hardware, positioners
May 1, 2006 — Melles Griot has added to its online catalog a full line of optomechanical hardware, including optical rail and mounting systems, controllers for nanometric positioning, high-resolution positioning stages with manual or motorized actuators, and...
Heidelberg Engineering GmbH
May 1, 2006 — The FDA has granted clearance to Heidelberg Engineering GmbH’s SL-OCT optical coherence tomography device for cross-sectional anterior segment imaging. The system, mounted on a slit lamp for space economy and cost effectiveness, enables...
Hologic Inc.
May 1, 2006 — Hologic Inc. of Bedford, Mass., has entered into an agreement to purchase Suros Surgical Systems Inc. of Indianapolis, a developer of devices used for minimally invasive biopsy and tissue excision. The Indiana-based company’s products include...
Imaging is a key to progress in stem cell research
May 1, 2006 — An important aspect of stem cell research is the function of the cells that support them and enable them to function properly. These systems of supportive cells — called niches — sequester stem cells from apoptotic and differentiation...
Imaging methods
May 1, 2006 — Part of the “Methods Express” series, Cell Imaging covers key techniques that can be used in laboratories with access to cell imaging equipment. Although the 350-page book focuses on live-cell imaging and light microscopy applications,...
Imaging methods help detect and assess prostate cancer
May 1, 2006 — One man out of 11 develops adenocarcinoma of the prostate. Accurate detection and staging of the cancer are essential for its proper treatment and for the extension of patient life expectancy. In a review of the uses of computer technology in...
Invitrogen Corp.
May 1, 2006 — Invitrogen Corp. of Carlsbad, Calif., has entered into an agreement with the National Institutes of Health Chemical Genomics Center in Bethesda, Md., to identify small molecules that modulate key signaling pathways associated with disease...
Lab supplies
May 1, 2006 — The second edition of the SCP Science “Instruments & Supplies” catalog specifies new products for the inorganic chemical laboratory, including the PlasmaPure Plus high-purity acids, a variety of DigiSep solid-phase-extraction...
Laser-activated bubbles mitigate toil and troubles
May 1, 2006 — A number of biomedical applications take advantage of laser light interactions with tissue that are accompanied by absorption of light by tissue. As the absorbed energy converts into heat, it produces transient nonuniform thermal fields in cells,...
LC/MS systems
May 1, 2006 — A seven-page brochure from Agilent Technologies Inc. presents the company’s 6000 series LC/MS systems, which include triple-quadrupole and quadrupole-time-of-flight (Tof) instruments, and improved versions of the ion trap, Tof and...
MediSpectra Inc.
May 1, 2006 — MediSpectra Inc. of Lexington, Mass., has received FDA approval for the Luma cervical imaging system. When used in conjunction with colposcopy — for women who have had abnormal Pap test results — the noncontact optical imaging device is...
