Another camera will enable specialists to evacuate dangerous cells without harming sound tissue, decreasing the probability of the growth spreading.
The camera, which was created by scientists from the University of Illinois, imitates the visual arrangement of a butterfly, and gives both a conventional shading picture and a close infrared picture that permits fluorescently named malignant cells to be obvious, even under splendid surgical lighting, detailed the CNET.com site.
Viktor Gruev, research team leader and associate professor of electrical and computer engineering at the University of Illinois, said: “We looked to nature’s visual systems for inspiration, and we realized that the morpho butterfly, whose eyes contain nanostructures that sense multispectral information, can acquire both near-infrared and color information simultaneously.”
The researchers explained how their camera can detect tumors in animals and can help assess the stage of breast cancer in humans. The camera weighs less than an ounce and can be manufactured for about $20.
The camera’s ability to detect fluorescence markers under surgical lighting sets it apart from many of today’s FDA-approved near-infrared cameras, which are not sensitive enough to do this, according to the researchers. Room lights typically need to be dimmed to see the fluorescence.
The CNET.com website pointed out that the team is creating a start-up to commercialize the device.
They are also working with the FDA to design a clinical trials before approving its usage in hospitals.
Researchers from the University of Singapore had developed a new technique to deliver light to deep organs in the human body, in order to activate specific medicines that respond to light, based on a system known as Photodynamic therapy.
Although this therapy is considered among efficient cancer treatments, its impact is limited to tumors found near the skin, given that the light’s weak capacity prevents it from pass through tissues.
However, the new technique allows the application of the Photodynamic therapy on the body’s deep organs with high accuracy.
The new technique can be used in treating several types of cancer that affect inner organs like the brain and liver.
