1. A composition, comprising:
a nucleic acid array comprising a support having a plurality of first probes affixed to the support, wherein each of the first probes comprises 2, 3, 4, or 5 copies of a first nucleotide hybridization sequence; and
a plurality of second probes, wherein each of the second probes comprises (i) a second hybridization sequence complementary to the first nucleotide hybridization sequence, and (ii) a unique molecular identifier;
wherein:
two or more of the copies of the first nucleotide hybridization sequence in each of the first probes are hybridized to the second nucleotide hybridization sequence of the second probes;
each of the first probes and each of the second probes comprises a unique spatial barcode associated with a unique location on the nucleic acid array; and
the unique spatial barcode of each of the first probes and each of the second probes does not substantially hybridize to a nucleic acid in a biological sample.
