1. A tagged, functionalized particle comprising one or more functional moieties and a unique tag linked to a particle. 2. The functionalized particle of claim 1, wherein the unique tag is a nucleic acid, a peptide, an optically-encoded tag or a mass-encoded tag. 3. The functionalized particle of claim 2, wherein the unique tag is nucleic acid and the nucleic acid is DNA, RNA or XNA. 4. The functionalized particle of claim 3, wherein the nucleic acid is comprised of 5-150 nucleotides of known sequence. 5. The functionalized particle of claim 4, wherein the nucleic acid is single stranded. 6. The functionalized particle of claim 4, wherein the nucleic acid is double stranded. 7. The functionalized particle of claim 2, wherein the peptide is a short peptide, a peptoid, or a specific pattern of isotope labeled peptide. 8. The functionalized particle of claim 7, wherein the peptide or peptoid is 5-20 amino acids of known sequence. 9. The functionalized particle of claim 2, wherein the optically-encoded tag is one or a combination of fluorescent dyes, quantum dots, polymer dots, nanodiamonds, or FRET systems. 10. The functionalized particle of claim 2, wherein the mass-encoded tag is a lanthanide atom, either single species or combinations thereof, and is embedded within or attached to the surface of the particle. 11. The functionalized particle of claim 1, wherein at least one functional moiety is a monoclonal antibody, a polyclonal antibody, single chain antibody, a single domain antibody, a bi-specific antibody, an affibody molecule, a peptide, a peptoid, an aptamer, a small molecule or a chemical compound. 12. The functionalized particle of claim 1, wherein the functionalized particle comprises a first and a second functional moieties and the second functional moiety is different than the first functional moiety and is a monoclonal antibody, a polyclonal antibody, single chain antibody, a bi-specific antibody, a small molecule or a chemical compound. 13. The functionalized particle of claim 1, wherein the particle is a bead. 14. A method of preparing a tagged, functionalized particle comprising linking one or more functional moieties and a unique tag to a particle. 15. The method of claim 14, wherein the unique tag is a nucleic acid, a peptide, an optically-encoded tag or a mass-encoded tag. 16. The method of claim 15, wherein the nucleic acid is DNA, RNA or XNA. 17. The method of claim 15, wherein the unique tag is a nucleic acid and the nucleic acid is comprised of 5-150 nucleotides of known sequence. 18. The functionalized particle of claim 17, wherein the nucleic acid is single or double stranded. 19. The functionalized particle of claim 17, wherein the nucleic acid is single or double stranded. 20. The method of claim 15, wherein the peptide is a short peptide, a peptoid, or a specific pattern of isotope labeled peptide. 21. The method of claim 20, wherein the peptide or peptoid is 5-20 amino acids of known sequence. 22. The method of claim 15, wherein the optically-encoded tag is one or a combination of fluorescent dyes, quantum dots, polymer dots, nanodiamonds, or FRET systems (using components with sufficient spectral separation and unique optical properties). 23. The method of claim 15, wherein the mass-encoded tag is a lanthanide atom, either single species or combinations thereof, and is embedded within or attached to the surface of the particle. 24. The method of claim 14, wherein at least one functional moiety is a monoclonal antibody, a polyclonal antibody, a single chain antibody, a single domain antibody, a bi-specific antibody, an affibody molecule, a peptide, a peptoid, a small molecule, an aptamer or a chemical compound. 25. The method of claim 14, wherein the functionalized particle comprises a first and a second functional moieties and the second functional moiety is different than the first functional moiety and is a monoclonal antibody, a polyclonal antibody, single chain antibody, a bi-specific antibody, a small molecule or a chemical compound. 26. The method of claim 14, wherein the particle is a bead. 27. A method of screening a collection of uniquely tagged, functionalized particles to identify a functional moiety or combination of functional moieties having a desired property or properties, the method comprising preparing a collection of tagged, functionalized particles of claim 1, introducing the collection of tagged, functionalized particles into an assay to select for a specific property or properties; isolating the tagged, functionalized particles that manifest the desired property or properties; identifying the tags of the isolated tagged functionalized particles; and determining the functional moiety or combination of functional moieties from the identity of the tag. 28. The method of claim 27, wherein the assay is in vitro or in vivo. 29. The method of claim 27, wherein the desired property is a location, a concentration, a binding affinity, a pharmacokinetic, a pharmacodynamic or a chemical property of the functionalized particle. 30. The method of claim 27, wherein the tags are identified by nucleotide sequencing if the tags are nucleic acids; mass spectrometry if the tags are peptides or mass-encoded; or flow cytometry or microscopy if the tags are fluorescent dyes, quantum dots or nanodiamonds.
