Precise control of the architecture of multiple cells in culture and in vivo via precise engineering of the material surface properties is described as cell patterning. Substrate patterning by control of the surface physicochemical and topographic features enables selective localization and phenotypic and genotypic control of living cells. In culture, control over spatial and temporal dynamics of cells and heterotypic interactions draws inspiration from in vivo embryogenesis and haptotaxis. Patterned arrays of single or multiple cell types in culture serve as model systems for exploration of cell-cell and cell-matrix interactions. More recently, the patterned arrays and assemblies of tissues have found practical applications in the fields of Biosensors and cell-based assays for Drug Discovery. Although the field of cell patterning has its origins early in this century, an improved understanding of cell-substrate interactions and the use of microfabrication techniques borrowed from the microelectronics industry have enabled significant recent progress. This review presents the important early discoveries and emphasizes results of recent state-of-the-art cell patterning methods. The review concludes by illustrating the growing impact of cell patterning in the areas of bioelectronic devices and cell-based assays for drug discovery.

“…During the past decade, biocompatible materials have attracted more and more attentions due to their potential applications in biomedical and biotechnological fields [1][2][3][4][5]. Alginate, an anionic polysaccharide extracted from marine algae, is one of the most popular biocompatible materials, in view of its abundance, non-toxicity, non-immunogenicity, good biocompatibility, and water-solubility [6,7].…”

“…Polyurethanes is said to either be mechanically softer or stiffer than the PDMS, offer better adhesion and tear resistance, and is available in biocompatible formulations that exhibit excellent chemical resistance. In the current micro technology, Polyurethanes have been used as encapsulating structures of chemical sensors (Bratov et al 1995), have been widely used to study blood cells (Meyer and Biehl 1995) and to examine artificial gecko hairs (Campolo 2003). Artificial hair cell based on polyurethane elastomer and force sensitive resistors also have been developed and characterized by (Engel et al 2005a).…”

An artificial hair cell sensor is the current technology based on a biological inspiration and is widely used in underwater applications including the glider, robotic and autonomous surface vehicle. These papers discuss a few strategies in relation to the principles of sensing, fabrication, performance, and preliminary measurement data. The MEMS flow sensor is generally needed to replace existing commercial sensors that are inadequate for some applications. Material also provides some advantages to the hair cell sensor. Some materials such as Polydimethylsilaxone and Polyurethane have been investigated. The sensing element is reviewed including the doped piezoresistors, strain gauge and force sensitive resistors. Performance and result of each design will be presented briefly. Finally, the importance and the need for modeling, simulation and experiments will be reviewed based on the latest achievements on that particular research area.
