The efficiency and effectiveness of the use and delivery of medicinal drugs rely
on the natural system of an individual. Sometimes, these two factors can be deeply
hindered by an uncontrollable force that has no pattern, like the location of an infection within the body or a site of damage. However, in a recent development for a revolutionary device designed by the University of Manchester, a mechanically influenced machine, Rotaxane, can bypass these limitations and control the use and amount of a drug with unseen precision.
This device triumphs in functionality when it comes to being an accurate delivery
system for the most pinpoint problems. According to an article published by Nature, the device works by utilizing molecules called rotaxanes that are “well suited to act as force actuators due to their capability for large amplitude movements”(Chen, 2024) In other words, the rotaxane structures act as cargo ships for molecules and by mechanical forces can release medicinal particles. This device also has functions in problems that don’t have to do with the human body. Material conundrums as small as scratches on a device can be solved with the precision of rotaxane structures.
The most prevalent issue with the design of previous structures was the capacity
at which it dispenses the repair and medicinal molecules. According to a source
published by the University of Manchester, the newly developed rotaxane device
surpasses these limitations while still being able to disperse molecules with incredible
accuracy while increasing the capacity from one particle to five particles, with a
possibility for more in future research. This increase in capacity, coupled with research
being done to increase the types of molecules that are being released at once truly
make this device an astounding breakthrough in drug usage and medical practices.
Tests done to measure the reliability and adaptability of these structures were
successful and show great promise for further endeavors that could even reach
automatic applications like self-healing. The applications for these structures increase
day by day and the limits of use are yet to be discovered, if there are even any.
