摘要： A cell growth matrix for optimizing 3D organization nutrient delivery, controlling release of differentiation factors and facilitating attachment of cells to a scaffold Colloidal crystals and inverted colloidal crystals are used to form an ordered structure for use as a scaffold for tissue engineering. The porosity of the cell growth matrix may be modified by the selection of particles of appropriate diameter. Further, the surface of colloidal crystals can be easily modified to accommodate many organic species including biomolecules. Layer-by-layer materials are used for tissue engineering to control cell development by using sequential layering of bioactive species wherein the number and order of LBL layers deposited between layers containing a particular protein are controlled. LBL may also be used for timed release of bioactive species. Increased control differentiation factors release and control of cell attachments to the scaffold are achieved to better mimic natural tissue development.

摘要： The present teachings relate to the application of electrical impedance tomography (EIT) to demonstrate the multifunctionality of carbon nanocomposite thin films under various types of environmental stimuli. Carbon nanotube (CNT) thin films are fabricated by a layer-by-layer (LbL) technique or other techniques and mounted with electrodes along their boundaries. The response of the thin films to various stimuli determined by relying on electric current excitation and corresponding boundary potential measurements. The spatial conductivity variations are reconstructed based on a mathematical model for the EIT technique. Here, the ability of the EIT method to provide two-dimensional mapping of the conductivity of CNT thin films is validated by (1) electrically imaging intentional structural defects in the thin films and (2) mapping the film's response to various pH environments.
