Abstract: To remove phosphate (P i ) from wastewater, a novel, low-cost adsorbent was developed by immobilizing copper ions (Cu2+) on a naturally available biopolymer chitosan. The copper ions bound to chitosan through its complex formation with the amino and hydroxyl groups in the polymer chain. This complex formation could reduce the size of the hydrogels and thus increase the density of the natural biopolymer. The chelating interaction between nitrogen and copper enabled the intra- and inter-molecular cross-linking, thereby improving the physical and chemical stability of the polymeric ligand exchanger. Most importantly, Cu 2+ ions could serve as the active functional group for Pi removal from aqueous solution. The polymeric ligand exchanger displayed a greater affinity with P i rather than sulfate due to the electrostatic and Lewis acid/base interactions between immobilized Cu 2+ and P i , regardless of the solution pH. Batch adsorption experiments showed that the polymeric ligand exchanger had the maximum capacity of approximately 85 mg/g in Pi solutions. The polymeric ligand exchanger could also be applied to a fixed-bed column reactor, demonstrating the high performance on the Pi removal from aqueous solutions. ？ Springer Nature Singapore Pte Ltd. 2019.

Different techniques were employed to make the devices more bio-compatible and promote tissue repair; such as chemical surface modifications, using novel materials as the bulk of a device, physical topological manipulations and so forth. One of the strategies that recently gained a lot of attention is the use of tissue-inspired biomaterials that are coated on the surface of biomedical devices via different coating techniques, such as the use of extracellular matrix (ECM) coatings, extracted cell membrane coatings, and so on. In this chapter, we will give a general overview of the different types of tissue-inspired coatings along with a summary of recent studies reported in this scientific arena.
