A method of constructing nanotube matrix material in a controlled manner wherein, a nanotube fragment having at least two potential energy-binding surfaces including two distinct levels of binding potential energy of H-bonding and a second lower binding potential energy of covalent bonding, are used for binding corresponding nanotube fragments. In some implementations, the system may comprise one or more guest identification devices, one or more sensors, one or more host systems, and one or more processors. The transport module can be configured to place the biopsy needle adjacent to, or within, a target of interest within the breast. Further adjustment means to adjust the relationship between the end load and reaction pressures.
