A microfabricated droplet dispensing structure is described, which may include a MEMS microfluidic fluidic valve, configured to open and close a microfluidic channel. The opening and closing of the valve may separate a target biological particle containing genomic material, and a bead from a sample stream, and direct these two particle into a single droplet formed at the edge of the substrate. The droplet may then be encased in a sheath flow of an immiscible fluid, and provided to a sequencing module. The sequencing module may sequence the genomic material and/or an identifying barcode attached to the bead.

Microscopy imaging that allow for multiple mRNAs, proteins and metabolites to be spatially resolved at a subcellular level provides valuable molecular information which is a crucial factor for understanding tissue heterogeneity as for example within the tumor micro environment. The current invention describes a method (SUMI-Seq) which combines the use of Spatial Unique Molecular Identifier in situ sequencing and in vitro sequencing of rolonies derived from rolling circle amplification from padlock oligonucleotides targeting portion of RNA or cDNA transcript at a subcellular level with less limitation in the amount of transcripts and the length of the sequence that can be analyzed. Apart from padlocks oligonucleotides, the SUMI-Seq method can also be applied using circular oligonucleotides to spatially resolve proteins and metabolites to provide multiomics results.
