This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,509.

Summary of the Inventive Concept

A next-generation liposome-based system for targeted delivery of therapeutic molecules to diseased tissues, integrating pH-sensitive liposomes, nanoparticle-based targeting agents, and wearable devices for personalized medicine.

Background and Problem Solved

Despite advances in cancer diagnosis and treatment, existing methods for delivering therapeutic molecules to diseased tissues are limited by their lack of specificity, inefficiency, and inability to adapt to individual patients' needs. The original patent's liposome compositions and methods, while effective, are restricted to specific pH environments and lack the ability to monitor and respond to patients' physiological conditions.

Detailed Description of the Inventive Concept

The new inventive concept comprises a pH-sensitive liposome capable of releasing cargo in response to acidic microenvironments, a nanoparticle-based targeting agent that selectively binds to diseased tissue cells, and a wearable device that monitors the patient's physiological conditions and adjusts the liposome's release profile accordingly. This integrated system enables targeted delivery of therapeutic molecules, including RNA-based vaccines and CRISPR-Cas9 complexes, to specific cells or tissues, while allowing for real-time monitoring and adaptation to individual patients' needs.

Novelty and Inventive Step

The new inventive concept's integration of pH-sensitive liposomes, nanoparticle-based targeting agents, and wearable devices for personalized medicine represents a significant departure from the original patent's limitations, providing a more ambitious and forward-thinking approach to targeted therapeutic delivery.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different types of nanoparticles, liposome compositions, or wearable devices, as well as the integration of additional components, such as sensors or microfluidics, to further enhance the system's functionality and adaptability.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the fields of cancer treatment, gene editing, and personalized medicine, with potential applications in the development of targeted therapies, vaccines, and diagnostic tools.
