  • Publication number: 20220107246
    Abstract: The disclosure provides bifunctional tag constructs and related methods useful for transporting macrobiomolecules, such as nucleic acids and proteins, across plasma membranes. The bifunctional tags comprise an affinity domain conjugated to hydrophobic domain. The affinity domain is configured to noncovalently bind to the macrobiomolecule, whereas the hydrophobic domain is configured to interact with the plasma membrane. In certain embodiments, the plurality of bifunctional tags can noncovalently associate along the length of a macrobiomolecule, thus increasing the interaction with and penetration through the plasma membrane.

    Abstract: Briefly described, embodiments of this disclosure include structures, methods of forming the structures, and methods of using the structures. One exemplary structure, among others, includes a nanospecies and a porous material. The nanospecies has a first characteristic and a second detectable characteristic. In addition, a second detectable energy is produced corresponding to the second detectable characteristic upon exposure to a first energy. The porous material has the first characteristic and a plurality of pores. The first characteristic causes the nanospecies to interact with the porous material and become disposed in the pores of the porous material.
