Incorporation of rotaxane molecules into a lipid membrane transport studies must be water-soluble for delivery to the cell, but also. A polyrotaxane is a type of mechanically interlocked molecule (mim) consisting of strings and rings, in which multiple rings are threaded onto a molecular axle and prevented from dethreading by two bulky end groups more interestingly, as oligomeric or polymeric species of rotaxanes, these water-soluble can be applied into drug or gene carriers.
