What is UV VIS Spectroscopy?

UV VIS spectroscopy is a type of spectroscopy that uses ultraviolet-visible light to analyze a sample. UV VIS spectroscopy can be used to identify molecules, measure concentrations, and determine the structure of molecules. UV VIS spectroscopy is used in biomedical research to study biomolecules’ form and function and develop new diagnostic and therapeutic tools.

The Different Types of UV VIS Spectroscopy

UV VIS spectroscopy is a powerful analytical tool investigating various biochemical and biomedical processes. There are three main types of UV VIS spectroscopy: absorption, reflection, and fluorescence.

In absorption spectroscopy, light absorption by a sample is measured concerning wavelength. This can be used to determine the sample’s chemical structure and concentration.

The amount of light reflected off a sample as a function of wavelength is measured by reflection spectroscopy. This data can be used to calculate the sample’s surface structure and thickness.

When exposed to ultraviolet light, fluorescence spectroscopy measures the amount of light emitted by a sample. This data can be used to ascertain the presence and concentration of specific molecules in a sample.

What roles does UV/VIS spectroscopy play in biomedical research?

UV VIS spectroscopy is a versatile tool that can be used for various biomedical research applications. Among the most common applications of UV VIS spectroscopy in biomedical research are:

  • Determining the structure of biomolecules: Biomolecules like proteins and nucleic acids can have complex structures, which can be studied using UV-VIS spectroscopy. By studying the absorption spectrum of a biomolecule, researchers can obtain information about its secondary and tertiary structure.
  • Monitoring biochemical reactions: UV VIS spectroscopy can also monitor real-time biochemical responses. This allows researchers to study the kinetics of enzymes and other proteins involved in cellular processes.
  • Investigating cell viability: UV VIS spectroscopy can investigate cell viability by measuring the absorbance of cellular components such as DNA and proteins. This technique is often used in toxicity testing to assess the effects of chemicals or drugs on cells.
  • Diagnosing disease: UV VIS spectroscopy can diagnose conditions such as cancer by detecting changes in the absorbance of specific biomolecules associated with the disease.


UV-VIS spectroscopy is a precious tool in biomedical research that provides critical insights into the molecular structure of biomolecules. It can be used to determine the concentration, identity, purity, and reactivity of molecules from various biological samples, making it ideally suited for many areas of medical research. There are many competitive companies that provide high-quality products like Agilent UV VIS spectroscopy, this type of instrument is fast, reliable, and cost-effective, which has made this technique invaluable in advancing our understanding of how biology works at the molecular level.
