Scientists have developed a new type of light-responsive carriers that can be used to deliver substances into cells. These carriers, known as “light-responsive nanocarriers,” are made up of two parts: a targeting ligand and an encapsulated cargo. The targeting ligand binds to specific receptors on the surface of the cell, while the cargo is enclosed within the nanocarrier and is released only when the nanocarrier is exposed to light. This means that the cargo can be delivered to specific cells without affecting other cells in the body. This type of targeted delivery could be useful in a variety of applications, including drug delivery, gene therapy, and other forms of medical treatments.
