Provided herein is technology relating to depositing a material uniformly onto a surface and particularly, but not exclusively, to compositions comprising polymers near their entanglement concentrations and related methods and uses for depositing a material onto a surface uniformly. Accordingly, provided herein is technology that is general, aqueous-based, and does not require re-engineering or chemistry changes to the materials (e.g., beads and/or macromolecules) being deposited. In some embodiments, conventional spotting buffers are modified by dissolving one or more polymers in solution (e.g., aqueous or organic) to provide an even distribution of material (e.g., beads, macromolecules, etc.). |
