Researchers have been looking into how different metal compounds affect cells. They used a special tool called Raman spectroscopy to study this. This tool helps see changes inside cells without needing any labels. They tested three types of metal compounds: copper(II), manganese(II), and silver(I).
Milk powder is a big deal in many households. But what if it's not real? Fake milk powder can be risky. So, finding tricks to spot it is super important. A new method uses something called Raman spectroscopy. It's like a high-tech detective. This method can find fake stuff in milk powder, even when
Raman spectroscopy is making waves in the world of science. It's a powerful tool that can spot tiny particles in the air. These particles are called bioaerosols. They come from living things like plants, animals, and even us. Scientists use Raman spectroscopy to study these particles. It works by s
Alzheimer's disease is a growing concern, with millions of people affected worldwide. Early detection is crucial for better management and treatment. Two important indicators of this disease are monoamine oxidase B (MAO-B) and acetylcholinesterase (AChE). These substances are often elevated in indiv
Explosive identification is a crucial part of crime scene investigation. It often requires specialized teams to ensure safety. Handheld Raman spectrometers are popular tools for this job. They are portable, don't damage samples, and can detect various compounds with little preparation. However, they
The cyanobacterium Mastigocladopsis repens has a unique light-driven chloride pump. This pump is similar to the proton pumps found in archaea, but it moves chloride ions instead. One big question has been about the role of a late red-shifted photoproduct, known as the O intermediate. This intermedia
Deep in the frozen lands of Antarctica, scientists found a meteorite named Yamato 980115. This isn't your average space rock. It's a carbonaceous chondrite, a type of meteorite that's been around since the early days of our solar system. These rocks are like time capsules, holding clues about how wa
For a long time, DNA has been like the superhero of crime scene investigations But guess what? Too much evidence can overwhelm crime labs and create huge backlogs making this investigation process lengthy Moreover, many pieces of evidence at crime scenes can be body fluids.
Scientists are on a mission to pinpoint the exact moment when neurons, grown in a lab, reach full maturity. This time, they're using a nifty tool called Raman spectroscopy and a clever method known as Dynamic Network Biomarker (DNB) analysis. The goal? To spot the critical shift during neuron develo
The COVID-19 pandemic has led to a global search for effective ways to detect the virus, SARS-CoV-2, beyond vaccines and therapies. One promising method is surface-enhanced Raman scattering (SERS), which boosts the signals of molecular probes using special nanomaterials. Gold and silver nanoparticle
