A publication in the NPG Asia Materials journal introduced a study around a new biomedical engineering concept that allows the real-time adjustment of nutrient absorption.
The research team 3d-printed a wearable external magnet device that allowed the direct control of the location and vibration of enteric-coated magnetic nanoparticles (EMNPs) in the small intestine. They monitored the gastrointestinal motility in real-time through a simple mobile app and found that this method could be used in future to adjust a person weight without diet or exercise.
