Applications of two focus fluorescence correlation spectroscopy in colloid and polymer science
Thermal fluctuations in liquid samples can be used to calculate the hydrodynamic radii (Rh) of observed particles. Therefore, it is necessary to generate scattering contrast between the observed particles and the surrounding liquid phase. In static- and dynamic light scattering (SLS/DLS) …

The synthesis of unimolecular polymers through iterative exponential growth and their applications in block copolymer phase segregation and biological systems
Absolute structural control over polymers - in terms of sequence, length, and stereochemistry - is a Holy Grail of polymer science. Inspired by Nature, polymer chemists over the last century have sought new methods and strategies to control these parameters. An inverse relationship exists, however, …
