In recent years, metal nanoparticles have showed great application prospect in the field of biological imaging, cancer diagnosis and treatment due to its unique optical scattering and optical absorption properties. In many metal materials, gold nanoparticles have caused concerns in the field because of its simple preparation, easy to modify advantages. However, the poor stability in physiological fluids environment and the potential toxicity of gold nanoparticles always restricts its...

Multispectral photoacoustic imaging, which combines laser optics and ultrasound imaging technologies, can reliably distinguish between benign and malignant prostate tissue, a new study indicates. Researchers at the University of Rochester looked at 42 prostatectomy specimens using the new imaging technique. Multispectral photoacoustic imaging, still in its infancy, predicted 25 out of 26 benign tissues correctly and 13 out of 16 malignant tissues correctly, said Dr. Vikram Dogra, lead...

Caltech interdisciplinary team develops advanced live-imaging approach For modern biologists, the ability to capture high-quality, three-dimensional (3D) images of living tissues or organisms over time is necessary to answer problems in areas ranging from genomics to neurobiology and developmental biology. The better the image, the more detailed the information that can be drawn from it. Looking to improve upon current methods of imaging, researchers from the California Institute of...

Developing drugs to combat or cure human disease often involves a phase of testing with mice, so being able to peer clearly into a living mouse's innards has real value. But with the fluorescent dyes currently used to image the interior of laboratory mice, the view becomes so murky several millimeters under the skin that researchers might have more success divining the future from the rodent's entrails than they do extracting usable data. Now Stanford researchers have developed an improved...

Harvard scientists push SRS microscopy to new levels of spatial, temporal precisionA novel type of biomedical imaging, made possible by new advances in microscopy from scientists at Harvard University, is so fast and sensitive it can capture "video" of blood cells squeezing through capillaries.Researchers led by Harvard's Brian G. Saar, Christian W. Freudiger, and X. Sunney Xie describe the work this week in the journal Science.The new technique, based on stimulated Raman scattering (SRS),...

Spotting a single cancerous cell that has broken free from a tumor and is traveling through the bloodstream to colonize a new organ might seem like finding a needle in a haystack. But a new imaging technique from the University of Washington is a first step toward making this possible. UW researchers have developed a multifunctional nanoparticle that eliminates the background noise, enabling a more precise form of medical imaging "“ essentially erasing the haystack, so the needle shines...

The next generation of imaging techniques could harness a technology that moves faster than the speed of light A study published in the July issue of The Journal of Nuclear Medicine (JNM) reports on investigative research of a novel optical imaging technique called "Cerenkov luminescence imaging (CLI)." According to the authors, the technique could lead to the faster and more cost-effective development of radiopharmaceuticals for the diagnosis and treatment of cancer and other conditions....

New research findings suggest that an experimental ultrasensitive medical imaging technique that uses a pulsed laser and tiny metallic "nanocages" might enable both the early detection and treatment of disease. The system works by shining near-infrared laser pulses through the skin to detect hollow nanocages and solid nanoparticles - made of an alloy of gold and silver - that are injected into the bloodstream. Unlike previous approaches using tiny metallic nanorods and nanospheres, the new...
