Cariogenic oral biofilms are strongly linked to dental caries around dental sealants. Quaternary ammonium monomers copolymerized with dental resin systems have been increasingly explored for modulation of biofilm growth. Here, we investigated the effect of

Analysis of Different Computational Techniques for Calculating the Polarizability Tensors of Stem Cells with Realistic Three-Dimensional Morphologies

Recent advances in synthetic biomaterial microenvironment design has enabled researchers to mimic the natural in vivo environment of the cell and, therefore, quantify the effect of the environment on the morphologies of stem cells. Recently, the National

Structural Insights into DNA-Stabilized Silver Clusters

Danielle Schultz, Robert G. Brinson, Fahriye N. Sari, Jeffrey Fagan, Christina Bergonzo, Nancy Lin, Joy Dunkers
The structure and dynamics of Ag complexes derived from single stranded DNA (ssDNA) is less understood than their double stranded (dsDNA) counterparts despite their great promise as fluorescent biological probes and sensors. In this work, we seek new

Targeting hMSC Response via Surface Carbonyl Groups, Contact Angle, and Protein Interactions
