The precision medicine has just taken a leap that until a few years ago seemed like science fiction. A group of researchers has presented a microrrobot capable of commute for him inside the human body y deliver medications exactly to the affected areareducing risks and increasing the effectiveness of treatment.
According to experts, this advance opens the door to safer therapies for diseases that require delicate interventions or difficult to access.
A scientific breakthrough guided by magnets
According to the team ETH Zurichthe device, approximately the size of a grain of sandcan navigate blood vessels using external magnetic fields what control your direction y speed. This engineering allows the microrobot to advance even through complex vascular structures, mimicking the way a doctor “drives” a miniaturized tool without the need for invasive surgery.
The researchers verified that the robot is capable of reaching areas where conventional treatments reach with difficultyopening possibilities to address thrombi, tumors or lesions within the vascular system.
A system designed to release drugs at the exact point
According to ICT Healthonce the microrrobot arrives at its destination, its structure can dissolve in a controlled manner to release medication that transports This implies that the entire process, navigation, delivery and disintegration, occurs within the organism without the need for additional intervention.
Furthermore, specialists point out that this technology could significantly reduce the side effects associated with powerful drugssince the dose does not need to be dispersed throughout the entire body: it only acts where it is really needed.
Medical applications with high potential
The researchers explain that this type of robots could be used for treat conditions that require a extreme precisionlike neurological problems, arterial blockages o certain types of cancer. According to ETH Zurichduring tests on complex models the microrobots managed to move stably even in the thin vessels of the brain, demonstrating an unprecedented level of control.
For specialists, this represents a crucial step towards a new generation of minimally invasive therapiespersonalized and with less risk for the patient.
The medicine of the future begins to take shape
Although this technology not yet ready for immediate clinical userecent advances indicate that the integration of microrrobots in real medicine it could be closer than previously thought. According to ICT Healththe following steps may include larger essaysimprovements in drug release mechanisms and the design of versions of these robots capable of transporting different types of treatment.
If their development continues to advance, these devices could transform medical practice by allowing less aggressive interventionsmore efficient therapies and treatments that adapt to the body from within.
