Discover UV-Visible Spectroscopy: A Key to Modern Biotechnology
In 2025, UV-Visible spectroscopy continues to establish itself as an essential method in the field of biotechnology. It allows the structure and concentration of biological molecules to be analyzed with impressive precision. Technological advances at companies such as Thermo Fisher Scientific, Agilent Technologies, and PerkinElmer have multiplied its possible applications, making this technique more accessible and powerful than ever. But what does this method actually consist of, and how is it used daily to advance research or the development of new drugs? This is what we will explore in detail, through its operating principles, its practical applications, and its challenges for tomorrow’s biotechnology.
UV-visible spectroscopy is based on a simple but powerful principle: when a molecule is exposed to light in the ultraviolet (UV) or visible range, it can absorb some of that light. The amount of absorption depends on the chemical nature of the molecule as well as its environment. Specifically, a spectrophotometer like those from JASCO or Shimadzu emits light at different wavelengths and then measures the light that passes through or is reflected by the sample. The difference collected is used to create a spectrum, which reveals the presence or concentration of specific species. The science behind this is closely related to laws like the Beer-Lambert law, which states that absorbance is proportional to the concentration of the substance. Understanding these principles is crucial for any application in biochemistry or biomedical research, as they determine the reliability and sensitivity of analyses. Components
