摘要：

This effort utilizes a genetically tunable system of bacteriophage to evaluate the effect of charge, temperature and particle concentration on biomaterial synthesis utilizing the coffee ring (CR) effect. There was a 1.6-3 fold suppression of the CR at higher temperatures while maintaining self-assembled structures of thin films. This suppression was observed in phage with charged and uncharged surface chemistry, which formed ordered and disordered assemblies respectively, indicating CR suppression is not dependent on short-range ordering or surface chemistry. Analysis of the drying process suggests weakened capillary flow at elevated temperatures caused CR suppression and could be further enhanced for controlled assembly for advanced biomaterials.
