Advance: non -invasive adhesive can:
Researchers have designed a new mechanical adhesive system that imitates the powerful suction organ of the Rémora. Nevertheless, or suction cup fish. Meanwhile, This system. Consequently, described in the journal Nature, can adhere to soft and slippery surfaces for days or weeks, an advance that solves a major problem in fields such as medicine and environmental sciences.
The MIT team has developed the device. In addition, called Musas (Mechanical Underwater Soft Adhetion System), by copying the unique anatomy of Rémora. For example, It combines a main suction disc with rows of smaller compartments to grasp irregular surfaces. The main innovation of the system is a set of tiny micro-actors made from a formal memory alloy. When exposed to body temperature. these needles are delicately overlooked in the tissues, creating a solid and reliable link that resists dislodge.
This technology advance: non -invasive adhesive can could revolutionize the administration of drugs. During testing on animals. the device managed to join the stomach wall to ensure sustained release from the Cabotégravir, a HIV drug, for a week, which could one day be an alternative to daily tablets or frequent injections. Researchers have also shown that the device could deliver RNA medication directly in the fabric of the stomach wall. thus avoiding the problem of digestion before reaching the target zone.
The device is also promising as a diagnostic tool. Equipped with an impedance sensor. he was able to stick to the esophagus of an animal model and monitor gastroesophageal reflux (GERD). This device could constitute a much more comfortable alternative to current GERD sensors. which require the introduction of a tube in the patient’s nose or mouth.
Beyond medicine, the team has demonstrated the potential of the system for animal and environmental sciences. They advance: non -invasive adhesive can managed to fix a temperature sensor to a living fish. which allowed them to accurately monitor the water temperature while the fish was swimming at high speed. Researchers now plan to optimize the platform for other uses, especially for the administration of clinical vaccines.
