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. 11,857,645.

Summary of the Inventive Concept

A revolutionary platform that leverages advanced near-infrared technology and nanoscale targeting to enable real-time tumor visualization, targeted cancer therapy, and enhanced patient outcomes.

Background and Problem Solved

The original patent's compositions of near IR closed chain, sulfo-cyanine dyes and prostate specific membrane antigen ligands were groundbreaking in enabling minimally invasive medical procedures. However, these compositions have limitations in terms of targeting specificity, imaging resolution, and therapeutic efficacy. The new inventive concept addresses these limitations by integrating cutting-edge nanotechnology, advanced near-infrared radiation, and novel targeting strategies to create a paradigm-shifting platform for cancer imaging and therapy.

Detailed Description of the Inventive Concept

The next-generation platform consists of a system comprising a near IR, closed chain, sulfo-cyanine dye and a prostate specific membrane antigen ligand, wherein the ligand is a nanoparticle that selectively targets and binds to cancer cells, and the dye is encapsulated within the nanoparticle to enhance fluorescence. This system enables real-time tumor visualization during surgical procedures using near-infrared radiation. The platform also includes a method for targeted cancer therapy, comprising administering the system to a patient, and using near-infrared radiation to activate the nanoparticle to release a therapeutic agent. Additionally, the platform encompasses a composition of matter comprising a near IR, closed chain, sulfo-cyanine dye and a prostate specific membrane antigen ligand, wherein the ligand is a nanobody that selectively targets and binds to cancer cells, and the dye is conjugated to the nanobody to enhance fluorescence.

Novelty and Inventive Step

The new claims introduce a novel combination of nanotechnology, near-infrared radiation, and advanced targeting strategies that overcome the limitations of the original patent. The inventive step lies in the integration of these disparate technologies to create a seamless, real-time imaging and therapy platform that enables unprecedented precision and efficacy in cancer treatment.

Alternative Embodiments and Variations

Alternative embodiments of the platform could include the use of different nanoparticle materials, varying near-infrared radiation wavelengths, and diverse therapeutic agents. Additionally, the platform could be adapted for use in various medical specialties, such as neurosurgery, cardiovascular surgery, or orthopedic surgery.

Potential Commercial Applications and Market

The next-generation cancer imaging and therapy platform has vast commercial potential, with applications in hospitals, clinics, and research institutions worldwide. The market for cancer imaging and therapy is projected to grow significantly in the coming years, driven by increasing demand for minimally invasive, targeted, and effective treatments. The platform's ability to enable real-time tumor visualization, targeted therapy, and enhanced patient outcomes positions it for significant market share and revenue growth.
