Neurodegenerative diseases like Parkinson's and Alzheimer's are characterized by irreversible neuron damage and limited natural repair mechanisms. While stem cell therapy holds great promise for regenerating neural tissue, it has long been hindered by inefficiencies in cell delivery and low differentiation rates. Current methods, including surgical implantation or magnetic actuation, often fail to ensure precise cell placement and controlled differentiation. Ultrasound stimulation, known for its deep tissue penetration and safety, has emerged as a potential solution, but conventional transducers lack the necessary precision. Magnetic cell-based microrobots (Cellbots) offer targeted delivery, but integrating them with differentiation techniques has remained largely unexplored….
