Cross-amplified Barcodes on Slides for Spatial Transcriptomics Sequencing
Spatial transcriptomics can reveal molecular signatures of tissue at spatial scales, but current technologies cannot integrate excellent accessibility and easy data-decoding. Here, we use oligonucleotides whose number is the square root of the number of spots to generate cross-amplified spatial barcodes on slides using microfluidic technology. This method can obtain microarrays with well-defined barcodes easily and at low cost, without post-decoding, which contributes to the popularization of spatial transcriptomics.
