Abstract:
The development of rapid and versatile coating strategies for interface and particle engineering is of scientific and practical interest. This presentation will cover self-assembly approaches for generating metal–organic thin films, with an emphasis on interactions between polyphenols and metal ions to assemble adaptive, nanometer-thin and stimulus-responsive films. Polyphenols have various inherent properties including universal adherence, ROS scavenging, and pH-responsiveness, while metal ions can impart additional functionality into the films such as fluorescence, catalysis, and magnetic responsiveness. The influence of polyphenol structure and metal ion composition on film properties will be discussed. Variations in the assembly approaches will be shown to result in vastly different materials, from 10-nm-thick films to micrometer-thick, free-standing macroscopic materials. For example, using a solid metal source, films can be continually grown in situ, or by using spray assembly, films with gradient optical properties can be generated. Examples of these metal–organic films (in particle form) and their interactions with biological systems will be presented, and our recent initiative on minimum information and reporting standards in bio-nanoscience will also be discussed.
