Abstract
The present disclosure provides systems and methods for making a hydrogel comprising a cell, cell nucleus, or one or more components derived from a cell or cell nucleus. A method for making a hydrogel may comprise providing a cell or cell nucleus, a first polymer, wherein the first polymer comprises a plurality of first crosslink precursors, each of the plurality of first crosslink precursors comprising an azide group; providing a second polymer, wherein the second polymer comprises a plurality of second crosslink precursors, each of the plurality of second crosslink precursors comprising an alkyne group; and crosslinking the first polymer and the second polymer via a reaction between a first section of the first crosslink precursors and a second section of the second crosslink precursors, thereby providing the hydrogel comprising the cell or cell nucleus.
