Light in the Darkness: From Crime Resolution to Biochemical Research

21 February 2025

Did you know that chemiluminescent light has helped solve crimes?

In many crime scenes, key evidence is not visible to the naked eye. But thanks to chemiluminescence, chemistry can illuminate the invisible. One of the most fascinating examples is luminol, a reagent capable of revealing hidden traces of blood. When sprayed onto a suspicious surface, this compound reacts with the iron in haemoglobin, emitting a bluish glow that has been crucial in solving numerous criminal cases.

But the power of chemiluminescence is not limited to forensic science. This chemical reaction is also a fundamental tool in biochemistry and life sciences, enabling the ultra-sensitive detection of biomolecules in techniques such as immunoassays, Western blotting, and biotechnology research. The same light that exposes evidence at a crime scene helps scientists worldwide decipher molecular processes with extraordinary precision.

How does chemiluminescence work?

Chemiluminescence occurs when a chemical reaction releases energy in the form of light without generating heat. This phenomenon takes place when an excited chemical compound returns to its ground state, releasing visible photons.

For example, in glow sticks, an internal membrane separates two reagents: an oxalate ester and a peroxide. When the tube is bent, the membrane breaks, mixing the reagents and triggering a reaction that produces a luminous emission.

In scientific applications, this same principle is used to detect biomolecules and chemical traces with extremely high sensitivity.
