Smart particles are tiny materials engineered to respond to specific stimuli, such as temperature, pH, or light. These particles can change their properties or behavior when exposed to these triggers, making them useful in various applications, including drug delivery and environmental sensing. Researchers are exploring the potential of smart particles in fields like medicine and materials science. For instance, in drug delivery, smart particles can release medication at targeted sites in the body, improving treatment effectiveness while minimizing side effects. Their adaptability makes them a promising area of study for future innovations.
