The invention relates to water soluble crosslinkable prepolymers for the preparation of chemically stable crosslinked polymer gels, a process for preparing the same, compositions containing the same and their use such as a medical or dental filler composition.

A polymerizable composition includes an amide compound represented by Formula (1) and a polymerization initiator.

An intracellular delivery vehicle of which surface is covered by a positive charge, an intracellular delivery complex in which a component or compound desired is loaded in the intracellular delivery vehicle, a temperature-sensitive probe comprising the intracellular delivery complex, and a method for measuring the intracellular temperature by the temperature-sensitive probe are disclosed. The intracellular delivery vehicle is useful on account of its capability of easily delivering the component or compound desired inside the cell without inhibiting cell proliferation.

A coated tubular construct for biological and industrial applications includes a plurality of channels, where each channel is radially surrounded by a wall comprising a first polymer, and a conformal coating comprising a second polymer is disposed on an outer and/or an inner surface of each wall. A method of producing a tubular construct includes 3D printing a template structure comprising a sacrificial material and a photoinitiator, and immersing the template structure in a first prepolymer solution comprising a first prepolymer and a co-initiator. During the immersion, the template structure is exposed to light, and the first prepolymer undergoes radical polymerization to conformally coat the template structure with the first polymer, forming a coated template. The sacrificial material is removed from the coated template, and a tubular construct comprising the first polymer is formed.

A method of preparing a polymer comprises the use of free radical vinyl polymerisation to form carbon-carbon backbone segments of the polymer, wherein the longest chains in the polymer comprise vinyl polymer chains interspersed with other chemical groups and/or chains. The product has the characteristics of a step-growth polymer comprising a mixture of polyfunctional step-growth monomer residues formed by vinyl polymerization.

In some examples, novel nanogel particles are described having dual functionality, temperature responsiveness and pH responsiveness. For nucleic acid sequencing, amplification primers are grafted to nanogel particles to form primer-grafted nanogel particles, and the primer-grafted nanogel particles are captured onto surfaces within a flow cell. Within flow cells such as used in SBS nucleic acid sequencing, each primer-grafted nanogel particle functions as a nano-well in the flow cell, thus eliminating the need for nano-wells in some examples.
