Asymmetric bifunctional silyl (ABS) monomers comprising covalently linked pharmaceutical, chemical and biological agents are described. These agents can also be covalently bound via the silyl group to delivery vehicles for delivering the agents to desired targets or areas. Also described are delivery vehicles which contain ABS monomers comprising covalently linked agents and to vehicles that are covalently linked to the ABS monomers. The silyl modifications described herein can modify properties of the agents and vehicles, thereby providing desired solubility, stability, hydrophobicity and targeting.

The mechanically induced melting properties of DNA were employed to achieve force labile membranes is described. Nucleobase pairs were used as mechanophores. Adenine and thymine functionalized complementary amphiphilic block copolymers were self-assembled into polymersomes. The nucleobases formed hydrogen bonds which were disrupted upon force stimulation. The exposure of the disconnected nucleobases to the hydrophobic matrix of the membranes lead to a change of permeability which permitted the exchange of water-soluble molecules throughout the polymer matrix. Moreover, the encapsulation of horseradish peroxidase enabled the reaction of luminol with hydrogen peroxide to yield a luminescence producing species similar to the marine bioluminescence. Moreover, the same nano-reactors were employed to catalyze the formation of a polyacrylamide gel when force was applied. Insights into the change of permeability of supramolecular networks upon force are provided. These systems are useful for drug delivery, as nanoreactors and for the selective release of curing agents for 3D printing, or fragrances.
