In Raman spectroscopy, a laser is used to irradiate a sample. Almost all of the light is scattered in an elastic manner, meaning no change in energy occurs. However, a small percentage of light is scattered in an inelastic manner, known as Raman scattering. This process was first observed by Indian scientist Sir Chandrashekhara Venkata Raman in 1928.
Shine a laser on a drop of blood, mucus, or wastewater, and the light reflecting back can be used to positively identify bacteria in the sample.
A team of Purdue University scientists led by Shihuan Kuang has received a $2.5 million grant from the National Institutes of Health to define the role of lipid droplets in muscle stem cell function, a study with implications in both humans and livestock.
Researchers have developed a Raman microscope that can acquire information hundreds of times faster than a conventional Raman microscope.
Bacterial detection can take hours, if not days, to complete—wasting valuable time for diagnosing diseases and choosing treatments.
Nanoparticle deposition specialists, Nikalyte Ltd announced that the company has signed a partnership agreement with global life sciences group Calibre Scientific.
AZoLifeSciences speaks to Dr. Catia Costa about her latest research that showed how class A drug use can be determined from a single fingerprint.
The Nobel Prize-winning revelation that ordinary cells might be induced to revert to their earliest pluripotent state heralded the start of the ethical stem cell era.
AZoLifeSciences speaks to Dr. Shinsuke Kunimura about his latest research which involved combining Raman spectroscopy and X-ray fluorescence to identify an individual from a single strand of hair.
Cancer cells are smart when it comes to anti-cancer drugs, evolving and becoming resistant to even the strongest chemotherapies over time.
As the plastic in our oceans breaks up into smaller and smaller bits without breaking down chemically, the resulting microplastics are becoming a serious ecological problem.
"If you eat mussels, you eat microplastics." This was already known to a limited extent about mussels from individual ocean regions. A new study by the University of Bayreuth, led by Prof. Dr. Christian Laforsch, reveals that this claim holds true globally.
During the investigations of crime scenes, even a single strand of human hair can make a significant difference in the evolution of a trial or case.
In crime scene investigations, a single strand of hair can make a huge difference in the evolution of a case or trial.
Raman spectroscopy is widely used in analytical sciences to identify molecules via their structural fingerprint. In the biological context, the Raman response provides a valuable label-free specific contrast that allows distinguishing different cellular and tissue contents.
Prof. DONG Zhenchao and Prof. HOU Jianguo from University of Science and Technology of China (USTC) of Chinese Academy of Sciences (CAS) improved the spatial resolution from 8 nm to ~8 Å of photoluminescence imaging. It realized sub-molecular resolution with single molecule photofluorescence imaging for the first time.
A research group composed of Professor Takayuki Shibata and his colleagues at Department of Mechanical Engineering, Toyohashi University of Technology has given greater functionalities to atomic force microscopy (AFM).
A function-based sequencing technique using optical tweezers and taking advantage of the properties of gravity is letting researchers analyze bacteria cells.
A method using noninvasive raman spectroscopy has been developed by scientists to measure blood glucose levels without the use of needles.
Russian scientists from the Federal Research Clinical Center of Physical-Chemical Medicine, the Moscow Institute of Physics and Technology, and Lomonosov Moscow State University have shown that it is possible to combine two incompatible components—a protein and a polymer—in one electrospun fiber.
