Nanotechnology may find disease before it starts

...e animals and placed them on their backs on a warm imaging table. Rosol said that Liu and her team are working on creating biodegradable nanoparticles. For the purposes of this study, however, the researchers wanted to use a hard substance, silica, to see if their idea would work. The strongest ultrasound s...

Malaria parasites develop in lymph nodes

In the first quantitative, real-time imaging study of the travels of the malaria parasite Plasmodium through mammalian tissue, researchers at the Pasteur Institute in Paris found the parasites developing in an unexpected place: the lymph nodes. The parasites' presence in the lymph nodes almost...

New RNAi tools enable systematic studies of gene function

...ell division during malignancy. Automated cellular imaging was used to efficiently identify dividing cells in thousands of samples. This approach uncovered more than 100 previously unknown growth regulators in addition to several known players, confirming the library's sensitivity as a vehicle for gene disco...

Fruit fly's beating heart helps identify human heart disease genes

...hers. The team's bioengineers adapted an existing imaging technology to visualize in detail for the first time the beating of the heart of a fruit fly, an insect the size of a grain of rice. The fly's heart is about the size of the period at the end of this sentence. After perfecting the new visualization ...

Rochester scientists develop fast-working biosensor

...hester research team calls the technology "arrayed imaging reflectometry." The system utilizes a silicon chip that is made so that laser light reflected off the chip is invisible unless the target bacteria are present. The target described in the Biosensors and Bioelectronics article is the bacteria Escheri...

Making medicine 'smarter'

.... Meyer-Baese hopes to utilize magnetic resonance imaging (MRI) -- which holds promise in better detection of hard-to-find cases of breast cancer -- to provide doctors with the more critical eyes of a computer. Despite the incredible potential of MRI technology, which cranks out at least 200 scans for a sin...

New, unique microscope for nanotech

... The confocal microscope allows three-dimensional imaging of samples, such as cells, and picks up structures tagged with fluorescent dyes. Instead of cutting a sample into thin slices, a researcher can focus through the entire sample and resolve it in three dimensions. The atomic force microscope uses an e...
