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. 11,857,643.

Summary of the Inventive Concept

This inventive concept adapts the original compositions and methods for enhanced fluorescence to address specific, narrow markets or unique operational environments, such as high-security needs, disaster relief, or extreme weather conditions.

Background and Problem Solved

The original patent's compositions and methods for enhanced fluorescence, while effective, have limitations in certain niche environments. For instance, high-security biomolecule analysis requires enhanced signal-to-noise ratios, while disaster relief biomolecule detection demands robustness in extreme conditions. This inventive concept addresses these limitations by introducing specialized variations and niche solutions.

Detailed Description of the Inventive Concept

The new claims encompass four distinct solutions tailored to specific environments. Firstly, a system for high-security biomolecule analysis utilizes a fluorescently labeled biomolecule with a dye to protein ratio of at least 10:1 and a quenching-reducing agent, such as a PEG-modified spacer molecule. Secondly, a method for disaster relief biomolecule detection employs a fluorescently labeled biomolecule conjugate with a spacer molecule and a fluorescent label, ensuring robust detection in disaster relief environments. Thirdly, a composition for extreme weather biomolecule imaging incorporates a sulfonated fluorescent label and a protein-stabilizing polymer as a stabilizing agent, maintaining the fluorescent signal in extreme weather conditions. Lastly, a system for secure biomolecule tracking utilizes a fluorescently labeled biomolecule with a dye to protein ratio of at least 20:1 and an encryption module that employs a PEG-modified spacer molecule as a key.

Novelty and Inventive Step

The new claims introduce novel combinations of spacer molecules, fluorescent labels, and stabilizing agents tailored to specific environments, providing an inventive step beyond the original patent. The use of PEG-modified spacer molecules as quenching-reducing agents and encryption keys, as well as the application of sulfonated fluorescent labels and protein-stabilizing polymers, constitutes a non-obvious advancement.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different spacer molecules, such as MS-(PEG)4, or varying the dye to protein ratio to optimize signal-to-noise ratios. Additionally, the incorporation of thermally-stable spacer molecules or encryption modules using alternative algorithms could further expand the scope of the inventive concept.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various industries, including biotechnology, pharmaceuticals, and medical diagnostics. The specialized solutions for high-security biomolecule analysis, disaster relief biomolecule detection, and extreme weather biomolecule imaging can address specific needs in these markets, providing a competitive advantage for companies that adopt these technologies.
