    Abstract: Embodiments of the present disclosure relate to method of preparing a substrate for sequencing by synthesis, including capturing library DNA to the surface using a low salt buffer solution prior to grafting primer oligonucleotides. Substrates prepared by the method described herein have increased monoclonality of clusters and sequencing by synthesis using the substrate prepared by the method are also described.

    Abstract: In an example, a target material is immobilized on two opposed sequencing surfaces of a flow cell using first and second fluids. The first fluid has a density less than a target material density and the second fluid has a density greater than the target material density; or the second fluid has a density less than the target material density and the first fluid has a density greater than the target material density. The first fluid (including the target material) is introduced into the flow cell, whereby at least some of the target material becomes immobilized by capture sites on one of the sequencing surfaces. The first fluid and non-immobilized target material are removed. The second fluid (including target material) is introduced into the flow cell, whereby at least some of the target material becomes immobilized by capture sites on another of the sequencing surfaces.
