Do We Exchange Ourselves with Others?

This research introduces and formalizes the concept of Interpersonal Microbiological Resonance (IMR) — a new biophysical framework describing the continuous, quantifiable exchange of microscopic biological particles between individuals sharing the same space. Combining principles from biophysics, microbiology, and aerosol dynamics, the study demonstrates that humans are not biologically isolated entities but emit and absorb complex mixtures of aerosols, skin corneocytes, volatile organic compounds (VOCs), bacteria, lipids, and environmental DNA. The project establishes a mathematical model for the IMR Radius (R) — the measurable distance within which five major particle types remain above environmental baseline — and integrates it with a diffusion–decay function to predict field persistence. Experimental correlations and computational simulations confirm that molecular fields can overlap, forming dynamic “zones of co-presence” that persist for up to 40 minutes after departure. Beyond theory, the research translates these discoveries into applied innovations: A CFD-based simulation engine visualizing human molecular clouds. A mobile exposure calculator estimating real-time molecular interaction. A fluorescent particle-capture gel, physically demonstrating microscopic exchange. By bridging molecular biology, physics, and human ecology, IMR transforms our understanding of individuality, proximity, and shared existence. It redefines personhood as a distributed biological system — one that is measurable, interactive, and dynamically resonant.
