A functionalized polyurethane polymer is provided, the polymer defined by the formula where each R' is independently derived from a diisocyanate, where each R&#x2033; represents the soft segment of the polymer, where n is the number of repeat units within the soft segment of the polymer, where m is the number of repeating mer units in the polymer, where each E is a pendant-functionalized amide unit chain extender, wherein the nitrogen atom of the amide group is part of the polymer backbone. A method for preparing the polymer is also provided.

Modification of segmented polyurethane properties by copolymerizing with pendant functionalized diols

A method includes providing a biological sample, providing a sample collection device, wherein the sample collection device includes a sample binding surface including a photodegradable polymer configured to bind the biological sample, contacting the biological sample with the sample binding surface of the sample collection device, and irradiating the sample binding surface and the bound biological sample using light emitted from a light source to initiate degradation of the photodegradable polymer of the sample binding surface to cause release of the biological sample.
