Abstract
Chemical biology generally highlights the modulation or control of life processes using chemical molecules. However, the rapid development of materials' science has resulted in the increasing application of various functional materials in biological regulation. More importantly, the state of art of creating the integration of materials, either the inorganic or organic matrices, with living organisms has opened a window of opportunity to add the multiplex function to organisms. In this review, we suggest a new concept of materials' biology that refers to promoting functional evolution of living organisms using material-based modification of structures, functions, and behaviors of biological organisms, which could change the modification of organisms from the current molecular-level regulation to materials' level. Thus, this review focuses on the recent achievements of material-based modification of organisms that evolves the biological function of cells, bacteria, and viruses using biomimetic strategies. The bioinspired strategies for material-based modification, including layer-by-layer, biomimetic mineralization, interfacial reactive deposition, etc., are briefly introduced. Furthermore, the interaction between materials and organisms has performed a broad function that is not retained by organisms at their native state, which results in the applications in structural support, protection, environment control, energy, vaccine improvement, and cancer treatment. The significance of material-based regulations of organism is to use rationally designed materials to endow new physiological functions to organisms, which provides another perspective to understand biological inorganic chemistry. The roles of materials in chemical regulations of biology are highlighted. New characteristics as well as functions can be achieved by integration the rationally designed materials onto/into living organisms, following material-assisted biological improvement/evolution.
