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. 11,857,545.

Summary of the Inventive Concept

A system utilizing high penetration prodrugs to monitor and control air quality in agricultural greenhouses, reducing pesticide use, improving crop yields, and conserving water.

Background and Problem Solved

The original patent disclosed high penetration prodrugs for treating pulmonary conditions. However, agricultural greenhouses face unique challenges in maintaining optimal air quality, which affects crop yields and requires excessive pesticide use. This new concept addresses these limitations by applying the core technology to a novel field, providing a solution for monitoring and controlling air quality in greenhouses.

Detailed Description of the Inventive Concept

The system comprises a high penetration prodrug composition capable of penetrating biological barriers and detecting pollutants. A sensor detects pollutant levels, and a controller adjusts ventilation based on detected levels. The prodrug composition can also be used to reduce pesticide use by releasing a pesticide, monitor pesticide levels, and adjust application rates. Additionally, the system can improve crop yields by releasing a growth-promoting agent and detect fungal diseases by releasing a fluorescent marker. The system's components can be integrated into existing greenhouse infrastructure.

Novelty and Inventive Step

The new claims introduce the concept of applying high penetration prodrugs to agricultural greenhouses, which is a novel and non-obvious application of the original technology. The inventive step lies in the adaptation of the prodrug composition to detect pollutants, reduce pesticide use, improve crop yields, and conserve water in greenhouses.

Alternative Embodiments and Variations

Alternative embodiments include using different types of sensors, adjusting the prodrug composition to target specific pollutants, and integrating the system with existing greenhouse management software. Variations of the system can be designed for different types of greenhouses, such as those used for specific crops or in various climates.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the agricultural industry, particularly in the greenhouse sector. The system can be marketed as a solution for improving crop yields, reducing pesticide use, and conserving water, appealing to environmentally conscious and cost-effective farmers.
