Abstract

We have proposed previously that the biocompatibility of biomaterial surfaces might be improved by mimicking the phospholipid components which are present on the external faces of cellular plasma membranes. This approach may have particular relevance to the generation of haemocompatible surfaces, since the distributional asymmetry of phospholipids in the plasma membranes of blood cells is critical to the maintenance of haemostasis. The simplest feature common to the external faces of essentially all the mammalian plasma membranes investigated so far is the high content of the electrically neutral, but zwitterionic, phosphorylcholine. The present communication describes the syntheses of a group of novel reactive species capable of covalently linking phosphorylcholine to a variety of polymer surfaces.

    Grafting PC on solid surfaces has also been achieved using siloxane chemistry through coupling of phospholipid derivatives with an aminosilane coupling agent on a silica surface such as glass or silicon wafers [53,54]. PC derivatives with dimethylchlorosilane were synthezised to coat glass by covalent bonding [55,56]. Silanated zwiterrionic PC molecules were recently prepared by the hydrosilylation reaction of the MPC monomer with triethoxysilane before covalent fixation on titanium alloy [57].

    The surface of a polymer can be nanostructured so as to engineer feature sizes above 50 nm, which are known to influence cell attachment, motility and activity quite independently of surface chemistry [114]. As a final remark, it is reported that late stage capsule density and thickness [115, 116] may well be conditioned by the early stage interactions, and so a shorter-term tissue model studied with the biofuel cell can have important heuristic implications for the rationalisation of the design of biofuel cells. If we consider that a major application for enzymatic BFCs is to provide an implantable power supply for medical devices, then the major challenges remain as being primarily physiological rather than purely electrochemical.
