Method For Preparation Of Micellar Hybrid Nanoparticles For Combined Therapeutic And Diagnostic Medical Applications

Technology Benefits

In-vivo stability allows for prolonged integrity in systemic circulation. Micellar structure allows delivery of a broad array of payloads, including, magnetic particles, quantum dots, or a therapeutic agent. Reduced cytotoxicity of both hydrophobic drugs and nanoparticle itself. Enables co-delivery of therapeutic agents and diagnostic agents that enable imaging.

Technology Application

Medical imaging Cancer diagnostics and therapeutics Diagnostic and therapeutics for various diseases Vaccines

Detailed Technology Description

This invention provides both the composition and a novel method for creating micellar hybrid nanoparticles that exhibit substantial in vivo circulation times, allowing them to contain a diverse payload for periods of time sufficient for delivery and subsequent release to a desired tissue. In addition, this technology readily facilitates the simultaneous targeted delivery of both therapeutic and imaging agents to diseased tissue in vitro or in vivo.
