  • What Lasers are Best for Raman Spectroscopy?
    Article - 4 Oct 2023
    Raman spectroscopy requires a concentrated source of light, such as a laser, to generate a Raman signal from a sample. The characteristics of the Raman excitation laser/Raman laser primarily affect...
  • What are the Applications of Plasmonics in Photonics?
    Article - 14 Aug 2023
    Plasmonics is an innovative concept in nanophotonics that combines the properties of both electronics and photonics by confining the light energy to a nanometer-scale oscillating field of free...
  • What is Photothermal Spectroscopy?
    Article - 14 Feb 2023
    A type of optical analytic technique called photothermal spectroscopy is a powerful tool to study heat that is produced as a result of light absorption in a sample that has been exposed to radiation.
  • Combining Microscopy and Spectroscopy to Analyze Ancient Egyptian Papyrus
    Article - 25 Jan 2023
    Researchers recently used cutting inspection techniques combining microscopy with spectroscopy to shed new light on millennia-old Egyptian papyrus, uncovering new information about this ancient...
  • What is Mass Spectrometry?
    Article - 28 Oct 2022
    Mass spectrometry is an analytical technique used for chemical identification. By ionizing and fragmenting the sample of interest and measuring the mass-to-charge ratios of the products formed, it is...
  • How Spectrometry Has Found Microplastics in Blood
    Article - 27 Sep 2022
    Researchers have recently used spectrometry to analyze blood samples. They found microplastics in the blood, highlighting the dangers of plastic pollution.
  • Atomic Force Microscopy for Nanoparticles
    Article - 24 Aug 2022
