“…MCAs are suitable for carrying a wide range of substances with different molecular weights, in particular, enzymes [30], polysaccharides [36], fluorescent dyes [37], neurotransmitters [34], hormones [31,32], and growth factors [35]. The studies have shown that polymer film with MCAs is sensitive to external stimuli such as ultrasound [29,30,32,38], magnetic field [39], and laser irradiation [30,36,40,41] if additional modifiers are used during their fabrication (magnetic nanoparticles and photoabsorbing agents, respectively). The choice of trigger for drug release in real medical practice must exclude a negative effect on drug load and consider material localization.…”
