Numerous studies have focused on utilizing AI based databases to scale up, optimize, and accelerate the development of nanocarrier drug delivery systems that are safe, effective, and stable. Endogenous triggers like pH variations, hormone levels, enzymatic actions, overexpression of biomarkers, glucose, or redox gradients are intrinsic to the body's disease state. These triggers can externally prompt or amplify drug release in affected areas . UV light's high energy can modify chemical bonds, facilitating drug delivery mechanisms. Its versatility makes UV a common stimulus in the research and applications for drug delivery. To design more effective UV-responsive drug delivery molecules, we employ pre-trained language models, fine-tuning on target molecule datasets, and machine-learning predictive models of molecular excitation energies.
