Abstract

Embodiments of the present disclosure provides for nanozymes, methods of making nanozymes, methods of using nanozymes, and the like.

Claims (22)

1. A nanozyme, comprising:

a nanoparticle having an enzyme and a plurality of recognition moieties attached thereto, and optionally having one or more protecting moieties attached thereto,

wherein the recognition moieties target a specific target molecule that reacts with the enzyme, and

wherein the recognition moieties and protecting moieties are at a density on the nanoparticle that substantially reduces non-target molecules from reacting with the enzyme.

2. The nanozyme of claim 1 , wherein the enzyme does not react with the recognition moieties and the protecting moieties.

3. The nanozyme of claim 1 , where at least two different types of enzymes are attached to the nanoparticle.

4. The nanozyme of claim 1 , wherein the enzyme is selected from the group consisting of: an endoribonucleases, an endodeoxyribonuclease, an endoproteinase, and a combination thereof.

5. The nanozyme of claim 1 , wherein the enzyme has a function selected from the group consisting of: hydrolysis, methylation, de-methylation, phosphorylation, oxidation, reduction, nucleic acid editing, and condensation.

6. The nanozyme of claim 1 , wherein the nanoparticle is selected from the group consisting of: a quantum dot, a metal nanoparticle, a magnetic nanoparticle, a metal oxide nanoparticle, a heterogeneous dimer, trimer, oligomer, and polymer nanoparticle, an assembly of multiple nanoparticles, a composite organic/inorganic nanoparticle, a single walled nanotube, a multiwalled nanotube, and graphene.

7. The nanozyme of claim 1 , wherein at least one of the recognition moieties is selected from the group consisting of: a sequence-specific DNA oligonucleotide, a locked nucleic acid (LNA), a peptide nucleic acid (PNA), an antibody, and a small molecule protein receptor.

8. The nanozyme of claim 1 , wherein the target molecule is selected from the group consisting of: a DNA, a RNA, and a protein.

9. The nanozyme of claim 1 , further comprising at least one protecting moiety, wherein the protecting moiety is attached to the nanoparticle.

10. The nanozyme of claim 9 , wherein the protecting moiety is chosen from the group consisting of: a DNA oligonucleotide, a locked nucleic acid (LNA), a peptide nucleic acid (PNA), a poly(ethylene glycol) (PEG), a poly(vinyl alcohol) (PVA), a poly(acrylic acid) (PAA), a poly(propylene furmarate-co-ethylenee glycol) (P(PF-co-EG)), a polyacrylamide, a polypeptide, a poly-N-substituted glycine oligomer (polypeptoid), a hyaluronic acid (HA), an alginate, a chitosan, an agarose, a collagen, a fibrin, a gelatin, a dextran, derivatives of each of these ligands, and a combination thereof.

11. The nanozyme of claim 10 , wherein the enzyme is selected from the group consisting of: an endoribonucleases, an endodeoxyribonuclease, an endoproteinase, and a combination thereof;

wherein the nanoparticle is selected from the group consisting of: a quantum dot, a metal nanoparticle, a magnetic nanoparticle, a metal oxide nanoparticle, a heterogeneous dimer, trimer, oligomer, and polymer nanoparticle, a composite organic/inorganic nanoparticle, a single walled nanotube, a multiwalled nanotube, and graphene;

and wherein the recognition moiety is selected from the group consisting of: a sequence-specific DNA oligonucleotide, a locked nucleic acid (LNA), a peptide nucleic acid (PNA), an antibody, and a small molecule protein receptor.

12. The nanozyme of claim 9 , wherein the protecting moiety has a function selected from the group consisting of: cell-uptake efficiency, selective cell-entry efficiency, substantially no toxicity, substantially no immunogenicity, and a combination thereof.

13. The nanozyme of claim 1 , further comprising a therapeutic agent.

14. The nanozyme of claim 1 , wherein the nanoparticle functions as an imaging agent.

15. The nanozyme of claim 1 , further comprising an inter-and intra-cellular traffic guiding moiety attached to the nanoparticle.

16. The nanozyme of claim 1 , further comprising an allosterically functional moiety, attached to the nanoparticle.

17. The nanozyme of claim 1 , further comprising the protecting moieties, wherein the protecting moieties provide an additional function selected from the group consisting of increasing colloidal stability of the nanozyme, substantially reducing the toxicity of the nanozyme, substantially reducing the immunogenicity of the nanozyme, and a combination thereof.
