Photothermal Activation

Meaning

Photothermal Activation is a biophysical process where specific materials, often nanoparticles or chromophores, absorb light energy and rapidly convert that absorbed energy into localized heat, leading to a therapeutic effect. This technique is utilized in targeted therapies, such as the selective destruction of abnormal cells or the controlled release of a pharmaceutical agent at a precise site within the body. It represents a non-invasive method for spatial and temporal control over biological processes.
