Engineering Stimuli‐Responsive Materials for Precision Medicine

Abstract

Over the past decade, precision medicine has garnered increasing attention, making significant strides in discovering new therapeutic drugs and mechanisms, resulting in notable achievements in symptom alleviation, pain reduction, and extended survival rates. However, the limited target specificity of primary drugs and inter‐individual differences have often necessitated high‐dosage strategies, leading to challenges such as restricted deep tissue penetration rates and systemic side effects. Material science advancements present a promising avenue for these issues. By leveraging the distinct internal features of diseased regions and the application of specific external stimuli, responsive materials can be tailored to achieve targeted delivery, controllable release, and specific biochemical reactions. This review aims to highlight the latest advancements in stimuli‐responsive materials and their potential in precision medicine. Initially, we introduce disease‐related internal stimuli and capable external stimuli, elucidating the reaction principles of responsive functional groups. Subsequently, we provide a detailed analysis of representative pre‐clinical achievements of stimuli responsive materials across various clinical applications, including enhancements in the treatment of cancers, injury diseases, inflammatory diseases, infection diseases, and high‐throughput microfluidic biosensors. Finally, we discuss some clinical challenges, such as off‐target effects, long‐term impacts of nano‐materials, potential ethical concerns, and offer insights into future perspectives of stimuli‐responsive materials.
