Partially nonhybridizing oligonucleotides are provided that contain two or more hybridizing segments, with any two hybridizing segments separated by a nonhybridizing spacer segment, i.e., a nucleotide or nonnucleotidic segment that has little or no likelihood of binding to an oligonucleotide sequence found in nature. Oligonucleotide arrays are also provided in which at least one of the oligonucleotides of the array is a partially nonhybridizing oligonucleotide. The partially nonhybridizing oligonucleotides serve as multifunctional probes wherein each hydrizing segment of a single partially nonhybridizing oligonucleotide serves as an individual probe. Also provided are methods for preparing and using the partially nonhybridizing oligonucleotides and arrays formed therewith. A particularly nonhybridizing oligonucleotides and arrays formed therewith. A particularly preferred method of array fabrication involves the use of focused acoustic energy.
