Quantum-Resolved Photonic Editing of Endothelial Gene Regulation

Quantum-scale photomolecular genetic editing is emerging as a precise, noncontact strategy for modulating endothelial function through controlled light–matter interactions. This paradigm integrates photonics, quantum-scale energy transfer, and molecular genetics to regulate intracellular signaling, gene expression, and barrier dynamics with high spatial and temporal fidelity. Red and near-infrared photons interact with chromophores, delocalized electron clouds, and mitochondrial respiratory complexes to generate quantized electronic excitations that propagate toward the transcriptional and epigenetic machinery. In endothelial cells, these processes influence oxidative stress, calcium flux, cytoskeletal restructuring, and tight junction integrity—the core determinants of vascular homeostasis and blood–tissue interface stability. Quantum-scale photomolecular editing enables reversible, tunable, and dose-dependent genetic modulation without exogenous vectors or permanent genomic alteration. This review synthesizes advances in photobiomodulation, quantum biology, and endothelial mechanobiology to outline mechanistic frameworks that connect photon absorption to molecular genetic outcomes. We discuss implications for neurovascular disorders, inflammation, and regenerative repair, and we highlight challenges in standardization, restructuring, and translational deployment.
