== Summary ==&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Fritz-Albert Popp&amp;#039;&amp;#039;&amp;#039; was a German biophysicist who pioneered the experimental investigation of &amp;#039;&amp;#039;&amp;#039;biophoton emission&amp;#039;&amp;#039;&amp;#039; — extremely low-intensity, spontaneous, coherent-like ultraweak photon emission from living cells and organisms. He founded the International Institute of Biophysics in Neuss, Germany, which became the international hub for biophoton research. Biophoton emission is now an established (if niche) area of biophysics.&lt;br /&gt;
&lt;br /&gt;
== Life ==&lt;br /&gt;
&lt;br /&gt;
Popp earned his PhD in theoretical physics at the University of Mainz (1966) and his Habilitation in biophysics at the University of Marburg (1973). His career was repeatedly disrupted by institutional opposition to his biophoton-research programme; he eventually founded the independent International Institute of Biophysics (IIB) in Neuss in 1996, which he directed until his death.&lt;br /&gt;
&lt;br /&gt;
== Key Contributions ==&lt;br /&gt;
&lt;br /&gt;
=== Biophoton detection and characterisation ===&lt;br /&gt;
&lt;br /&gt;
Popp&amp;#039;s experimental programme demonstrated that:&lt;br /&gt;
&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Living cells emit ultraweak photon flux&amp;#039;&amp;#039;&amp;#039; in the visible / near-UV range at intensities of ~ 10 to ~ 1000 photons per cm² per second — too weak for the unaided eye but reproducibly detectable with photomultiplier-tube apparatus in dark chambers.&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Emission intensity correlates with physiological state&amp;#039;&amp;#039;&amp;#039;: cell division, stress, disease, growth phase. Cancer cells, e.g., emit differently from healthy cells.&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Photon statistics show coherent-like behaviour&amp;#039;&amp;#039;&amp;#039;: squeezed-state or sub-Poissonian distributions in some conditions, distinct from the thermal-light statistics expected from incoherent chemiluminescence.&lt;br /&gt;
&lt;br /&gt;
=== DNA as biophoton source ===&lt;br /&gt;
&lt;br /&gt;
Popp proposed that &amp;#039;&amp;#039;&amp;#039;DNA itself is the principal biophoton source&amp;#039;&amp;#039;&amp;#039; — the emission spectrum, polarisation, and intensity scale appropriately with DNA content, and exciplex-formation in the stacked base pairs provides a plausible photophysical mechanism.&lt;br /&gt;
&lt;br /&gt;
=== Biological-coherence framework ===&lt;br /&gt;
&lt;br /&gt;
Popp&amp;#039;s broader theoretical framework treats the cellular biophoton field as a &amp;#039;&amp;#039;&amp;#039;coherent communication medium&amp;#039;&amp;#039;&amp;#039; coordinating biochemical activity across the cell and between cells — a form of intra-organism electromagnetic signalling complementary to molecular (hormone, neurotransmitter) signalling.&lt;br /&gt;
&lt;br /&gt;
== Reception ==&lt;br /&gt;
&lt;br /&gt;
The &amp;#039;&amp;#039;&amp;#039;existence of biophoton emission&amp;#039;&amp;#039;&amp;#039; is now well-established and reproducible across many independent laboratories. The &amp;#039;&amp;#039;&amp;#039;interpretation&amp;#039;&amp;#039;&amp;#039; of biophoton emission as a coherent biological-communication channel remains contested; some researchers treat it as a meaningful biological signal, others as a metabolic by-product.&lt;br /&gt;
&lt;br /&gt;
In the [[Psionics|psionic framework]], biophoton emission is one of the principal candidate &amp;#039;&amp;#039;&amp;#039;empirical entry points&amp;#039;&amp;#039;&amp;#039; for ψ-field coupling: a measurable, coherent-like electromagnetic phenomenon in biological systems whose intensity and statistics are state-dependent and potentially environmentally-modulated.&lt;br /&gt;
