What to know about 'Switchable' smart gel may pave way for next-gen drug delivery and sensing tech

Scientists at the University of Birmingham have developed a multi-responsive smart gel using synthetic foldamers that can transition between gel and liquid states via ultraviolet light, heat, or acid. The researchers utilized DNP NMR spectroscopy to analyze the material's atomic structure, suggesting future applications in targeted drug delivery and smart sensing technology.
