Advancing thermal field-flow fractionation for industrial polymer characterization
… its open channel design and ability to separate polymers and colloids. The applied field in an FFF technique determines the physiochemical properties by which the separation occurs. A well-established theory relates retention time to a retention parameter that is defined by the interaction …

Advances in single molecule spectroscopy and microscopy for biological imaging and polymer characterization
… individual Cy5 dye molecules conjugated to a polymer dendrimer scaffold, which allows for increases in the total brightness of the molecules. In addition, we designed a series of 'self-healing' dendrimers that have a photoprotective molecule, Trolox, covalently attached to the probes, thereby …

Advancing the field of polypeptoids through the synthesis of novel architectures and thermoresponsive polymers
Peptidomimetic polymers are an emerging class of polymers that are structurally related to polypeptides. Due to their structural similarities, these polymers can be used to study some of the physical aspects of polypeptides (for example, protein folding). They are also increasingly being used in …
