“…Each slide was then dipped in a solution of 3% 3‐acryloxypropyl trichlorosilane (AcPTS, United Chemical Industries Inc., Bristol, PA) in chloroform. The chemistry of AcPTS modification is presented in Figure 1 35. The slides were serially rinsed in chloroform and ethanol before being cured overnight in a vacuum oven at 25°C.…”

The extracellular matrix and extracellular matrix-associated proteins play a major role in growth and differentiation of tissues and organs. To date, few methods have been developed that allow researchers to examine the affect of surface density gradients of adhesion molecules in a controlled manner. Fibroblasts cultured on surfaces with a surface density gradient of RGD peptide aligned parallel to the gradient while fibroblasts on constant density RGD surfaces spread but did not align as has been shown in numerous earlier studies. Not only did fibroblasts align on the gradient surfaces, but they also showed significantly greater elongation than on constant density peptide surfaces or on control surfaces. This type of method is easy to replicate and can be used by laboratories interested in investigating alignment of various cell types without mechanical force or other stimulation, and without cell-cell interaction or for investigation of affects of surface density gradients of molecules on cellular biochemistry and biophysics. This method also has potential applications for developing scaffolds for tissue engineering applications where cellular alignment is necessary.

“…It is often requested the interface between the two materials in the composites should be well adhesive. Organo‐functional silanes, represented as RSiX 3 , are often used as coupling agents to enhance the adhesion between polymer and silica filler 13. The methoxy or ethoxy groups, represented by X, can be hydrolyzed with water.…”

Silane coupling agents are often used to improve the properties of composite materials by modifying interfaces. The coupling agents typically contain trichloro, trimethoxy, or triethoxy groups attached to silicon at one end. These inorganic groups hydrolyze, condense, and adsorb at oxide interfaces to form a bond with the coupling agents. The other end of the molecule typically contains organofunctional groups that are chosen to react or to be compatible with an organic polymer resin. The coupling agents are particularly effective for improving the mechanical properties of composites when water is present. The appropriate selection of the coupling agent is of importance for optimal improvement of the mechanical properties of the composite materials. Factors to be considered are the type of chemical bonding desired, compatibility between the coupling agent layer and resin, and the mechanical properties of the interphase.
