Abstract

The present invention provides an enzyme-powered nanomotor, comprising a particle with a surface, an enzyme, and a heterologous molecule; characterized in that the enzyme and the heterologous molecule are discontinuously attached over the whole surface of the particle. The invention also provides the nanomotor for use in therapy, diagnosis and prognosis, in particular, for the treatment of cancer. Additionally, the invention provides the use of the nanomotor for detecting an analyte in an isolated sample.

Description

[0001] This application claims the benefit of European Patent Application EP18382896 filed on December 5, 2018. technical field [0002] The invention belongs to the field of nanotechnology. In particular, the present invention relates to externally functionalized enzyme-driven nanomotors. The nanomotors of the present invention are particularly useful for therapy and biosensing. Background technique [0003] Catalytic microswimmers are artificial systems capable of self-propulsion due to the conversion of chemical energy into mechanical force and ultimately into active motion. [0004] Although chemically driven micro- and nanomotors have shown promising applicability in many fields, such as environmental remediation, cargo transport and delivery, tissue and cell penetration, and in vivo delivery of active drugs to the stomach, their use in biomedical Implementation in chemistries is often limited by the fuel's inherent toxicity or limited availability in living organisms...
