Micelles and Nanoplastics as Silent Physical Equalizers of Life Why Non‑Toxic Systems May Represent a Fundamental Environmental Threat

Micelles formed by surfactants and nano- to microplastic particles represent ubiquitous physical structures in modern aquatic environments. Unlike classical toxic agents, these entities exhibit low chemical reactivity and rarely trigger acute biological responses. Here we propose a physical interpretation in which micelles and nanoplastics act as mobile near-equilibrium objects that progressively destabilize lipid interfaces. By mediating the transport of hydrophobic compounds and interacting directly with cellular membranes, these structures promote slow redistribution of lipids, increased membrane permeability, and reduced mechanical stability. Rather than driving biological systems into chaotic states, micelles and nanoplastics facilitate relaxation toward thermodynamic equilibrium, thereby weakening the far-from-equilibrium conditions essential for life. This work frames micelles and nanoplastics as a previously underrecognized category of environmental stressor: silent physical equalizers that erode membrane integrity over time. Such mechanisms may exert chronic pressure on microbial and planktonic ecosystems, not through classical toxicity, but through gradual degradation of the physical boundaries that sustain living systems.
