Field-induced coherence and Fröhlich condensation in hydrated DNA

Area of Science:

• Quantum Biology
• Biophysics
• Condensed Matter Physics

Background:

• Hydrated DNA exhibits complex behaviors under external stimuli.
• Quantum phenomena in biological systems are increasingly recognized.
• Understanding DNA's response to electromagnetic fields is crucial for bioenergetics.

Purpose of the Study:

• To investigate macroscopic quantum coherence in hydrated DNA under magnetic fields.
• To explore the role of water layers in DNA's quantum properties.
• To elucidate the mechanism of field-induced coherence and its implications.

Main Methods:

• Confining hydrated DNA in quasi-two-dimensional water layers.
• Applying moderate magnetic fields (up to 0.5 T) at controlled temperatures (6°C) and DNA concentrations (100-1000 ng/μL).
• Measuring transverse and longitudinal voltage responses and performing Fourier analysis.

Main Results:

• Observed a sharp transverse voltage jump and regular oscillations near 100 mT at 6°C and low DNA concentration.
• Coherence onset was earlier at lower temperatures and DNA concentrations compared to room temperature.
• Evidence for a Fröhlich-like condensate stabilized by field-induced energy localization and geometric coherence domains ('Riemann slices').

Conclusions:

• Results support a hierarchical model of vibrational condensation and geometric coherence in DNA-water systems.
• The findings suggest potential implications for understanding bioenergetics and biological magnetosensitivity.
• Macroscopic quantum coherence in DNA can be achieved under accessible experimental conditions.
