Kinetic Effects on Self-Assembly and Function of Protein-Polymer Bioconjugates in Thin Films Prepared by Flow Coating

Structural proteins often in the form of micro and nanofibers, constituting most of intra- and extracellular matrix (ECM), are the fundamental building blocks of life [1]. Recent efforts to replace diseased or damaged tissues and organs have resulted in the molecular design and genetic engineering of recombinant proteins, and the advent of new technology for fabricating structural proteins into micro-/nanofibrous scaffolds, hoping to resemble some or all the characteristics of ECM structure and function. The fabrication of such an ECM mimic may be an important step in engineering a functional tissue. To this end, we have produced a series of silk-elastin-like proteins (SELPs) [2]. Revealed by our subsequent studies, SELPs in the form of hydrogels, thin films, and microfibers, have displayed a set of outstanding biological and physical properties. In this study, electrospinning will be pursued as a mechanism for the formation of SELP nanofibers.

C60 Films

We report an ultra-high vacuum low-temperature scanning tunneling microscopy (STM) study of the C60 monolayer grown on Cd(0001). Individual C60 molecules adsorbed on Cd(0001) may exhibit a bright or dim contrast in STM images. When deposited at low temperatures close to 100 K, C60 thin films present a curved structure to release strain due to dominant molecule–substrate interactions. Moreover, edge dislocation appears when two different wavy structures encounter each other, which has seldomly been observed in molecular self-assembly. When growth temperature rose, we found two forms of symmetric kagome lattice superstructures, 2 × 2 and 4 × 4, at room temperature (RT) and 310 K, respectively. The results provide new insight into the growth behavior of C60 films.
