In the quiet darkness of our bodies, a faint light carries messages we are just beginning to decode.
Imagine if every cell in your body communicated through an intricate language of light. This isn't science fiction—it's the emerging science of biophotons. These ultraweak photon emissions, first suspected a century ago, represent a form of cellular communication that operates beneath the awareness of our chemical and electrical signaling systems. All living organisms, from plants to humans, emit this faint glow, though it's 10,000 times weaker than what our naked eyes can detect. Today, with revolutionary sensing technologies, scientists are learning to read this light, uncovering its potential to revolutionize how we understand health, disease, and even consciousness itself.
Biophotons, or ultraweak photon emissions (UPEs), are subtle light particles emitted by all living matter. Unlike the dramatic glow of bioluminescent fireflies, this light is incredibly faint—typically between 1-1,000 photons per second per square centimeter across the visible and ultraviolet spectra 2 3 .
This phenomenon was first hypothesized in 1924 by Russian biologist Alexander Gurwitsch, who observed that onion roots seemed to stimulate cell division in neighboring roots through an invisible radiation 1 4 . The scientific community largely overlooked these findings until German biophysicist Fritz-Albert Popp advanced the research in the 1970s, coining the term "biophoton" and proposing DNA as a primary source 1 3 .
Scientists debate two primary explanations for biophoton origin:
Most researchers now believe both mechanisms may coexist, with some photons being metabolic waste while others form a sophisticated communication network 4 .
Alexander Gurwitsch first hypothesizes "mitogenetic radiation" after observing onion root stimulation 1 4 .
Fritz-Albert Popp advances research, coins term "biophoton," and proposes DNA as primary source 1 3 .
Improved detection technologies enable more precise measurements of ultraweak photon emissions.
First experimental measurements of biophotons from astrocytes and glioblastoma cells 2 .
Recent research has demonstrated biophotons' potential as diagnostic tools, particularly in brain cancers. A pioneering study conducted in 2025 marked the first experimental measurements of biophotons from astrocytes (normal brain cells) and glioblastoma cells 2 .
The research team from INFN-Frascati and Tor Vergata University designed ultra-sensitive detection systems to measure biophotons from cell cultures 2 :
The experiments yielded compelling results:
This breakthrough demonstrates that biophoton analysis can distinguish between normal and cancerous brain cells, potentially offering a non-invasive diagnostic approach for brain tumors and other conditions 2 .

| Diffusion Entropy Analysis (DEA) | Analyze complex patterns in time-series data | Reveals hidden information in photon emission dynamics 2 4 |
| Spectroscopic Filters | Isolate specific wavelength ranges | Determines spectral composition of biophoton emissions 4 |
The implications of biophoton research extend far beyond basic science, promising transformative applications across medicine and technology.
Biophoton detection offers potential for non-invasive disease monitoring. Researchers found that stressed plant tissues emit significantly more biophotons than healthy areas, suggesting similar principles might apply to human tissue damage 8 . The technology might eventually detect cellular changes long before physical symptoms appear.
In 2025, scientists reported the first detection of biophotons from working human brains through the skull. Intriguingly, emission patterns changed when participants switched between cognitive tasks, though not in the straightforward way researchers expected 7 . This has led to theories that biophotons might represent a third channel of neural communication alongside well-established electrical and chemical signaling 7 8 .
Some researchers are exploring even more revolutionary possibilities, suggesting that the human body's liquid crystal structures might enable photons to behave as "liquid light" through formations called exciton polaritons 1 6 . This could potentially allow for sophisticated information processing that bridges quantum and classical biological realms.

Biophoton research continues to accelerate, fueled by advances in detection technologies and analytical methods. The global biophotonics market, valued at $68.4 billion in 2025, is projected to reach $113.1 billion by 2030, reflecting growing investment and innovation 9 .
As research progresses, we may witness a paradigm shift in medicine and biology—from seeing the body as merely a biochemical machine to understanding it as a dynamic, light-informed system. The silent glow within all living things may soon reveal secrets about health, consciousness, and life itself that we're only beginning to imagine.
