A Systems Approach to the Modeling and Control of Molecular, Microparticle, and Biological Distributions
… distributional robustness analysis. Free radical bulk polymerization is the model system for molecular distributions. In situ ATR-FTIR spectroscopy was used to determine monomer concentration; off-line gel permeation chromatography was used to determine the molecular weight distribution. Kinetic …

Novel Poly(N-substituted glycine)s : synthesis, post-modification, and physical properties
… polymers via either chain- or step-growth polymerization were targeted. A 3-step synthetic approach towards N-substituted glycine N-carboxyanhydrides (NNCA) was implemented, or developed, and optimized allowing for an efficient gram scale preparation of the aforementioned monomer …

Actin dynamics in silico, in waves, and in rods
… dynamics during treadmilling but not during bulk polymerization. Using an exact stochastic simulation, we investigated whether filament-annealing and -fragmentation might account for faster than expected dynamics; their influence on actin dynamics had not been investigated before in a …

Boosting Biodetection Signals via Photopolymerization: Strategies for Photocatalyst Amplification
Photopolymerization-based signal amplification (PBA) is a method to enhance biodetection signals by coupling molecular recognition events with photocatalyst labels (eosin Y) and amplifying through visible light-initiated free radical polymerization. Leveraging inherent amplification in the radical …
