With current systems that use paper test strips, pH or blood sugar can be measured, but more complex chemical assays can’t be perfomed. Purdue researchers have now, however, introduced “paper microfluidics” by etching patterns by laser using readily available hydrophobic paper.
Researchers at Columbia University are the first to use tiny transistors to study single-molecule interactions and the mechanics of DNA-DNA binding over short time scales. Prior to this latest work, scientists have relied on fluorescence techniques, but the speed of these methods is limited.
New DNA sequencing and analysis services from PerkinElmer offer scientists the capability to outsource their genome sequencing requirements, and provides secure, scalable DNA sequencing and data interpretation to explore the genomic origins of disease.
In new experiments, researchers at the Niels Bohr Institute have measured the temperature of nano-sized gold particles with extreme precision and have examined their ability to melt the lipid membranes surrounding cells, paving the way for dissolving sick cells.
Because light microscopy can only penetrate the outermost layer of tissues, any region of the brain deeper than 700 micrometers cannot be reached by traditional microscopy techniques. Researchers at Stanford University have broken through this barrier by placing tiny glass tubes, about half the width of a grain of rice, in the deep brain of an anaesthetized mouse.
Consumers who get their DNA tested for health risks take the results in stride, according to a study conducted by Scripps Health and the U.S. government. It showed that recipients of genetic testing similar to "direct-to-consumer" options not available not only didn't sweat the results, they didn't act on them either, such as eating better or exercising more.
A new video from Phenomenex highlights the measures researchers can take to get the most out of new core-shell technology columns that can, when used properly, yield UHPLC results on a standard liquid chromatography system.
Addressing needs on electron microscopy for life science, FEI Company has released four software packages that help with automation, navigation, and data processing capabilities for the 3-D ultra-structural imaging of biological systems
Veeco Instruments Inc. has designed its new IRIS models for Innova and BioScope Catalyst atomic force microscopes (AFMs) to provide superior integration and accessibility for combined AFM and Raman spectroscopy research.
Enhanced 25-mm and 50-mm lenses from Navitar Inc. are specifically designed for short-wavelength infrared (SWIR) cameras. The lenses function in the wavelengths of 500 nm to 1700 nm, with 90% +/- 5% transmission across the range.
In other forms of spectroscopy, wavelength absorption generates measurement data. In the infrared (IR) wavelength, however, the key phenomena for measurement are the vibrational frequencies generated by the molecular bonds under analysis.
