Now, 25 years later, commercially available arrays contain several million oligonucleotides and are routine tools in Biological Immobilization 271 8,9 Patterning Methods 271 the laboratory. Oligonucleotide arrays have been used in Detection Methods 272 clinical applications to better understand viruses and human disease, for genetic screening, and for the implementation of Current Approaches and Commercialization 273 10,11 Applications 276 personalized medicine. The rapid pace of technical Summary 279 advancement of the early arrays, which performed rather Author Information 279 poorly, has led to the robust and inexpensive arrays currently in Corresponding Author 279 use. By analogy, peptide arrays are still at the early stage of ORCID 279 development and can be expected to see improvements that Notes 279 result in an important, if somewhat less ubiquitous, technology Biographies 279 for the life sciences.
