Surface nuclear-penetrating molecular drill enzyme (SNP-drill)

The term Surface nuclear-penetrating molecular drill enzyme does not refer to a naturally occurring biological enzyme or a standard therapeutic receptor. Instead, it describes a class of synthetic, light-activated molecular machines, often referred to as molecular motors or drills, developed for nanomedicine applications. These molecules, typically based on unidirectional rotary motors like those pioneered by Bernard Feringa, are designed to rotate at millions of cycles per second when triggered by specific wavelengths of light. This mechanical action allows them to physically drill through cellular and nuclear membranes, either to induce direct cell death (necrosis) or to facilitate the delivery of therapeutic payloads. While they are highly effective in vitro against cancer cells and antibiotic-resistant bacteria, they are considered experimental tools or delivery systems rather than traditional drug targets.
