摘要: A metamaterial laminate having at least the following elements (a) at least one polymer nanofiber mesh having polymer nanofibers embedded with conductive nanoparticles, and (b) at least two films, wherein the polymer nanofiber mesh is sandwiched between the two films. Included are methods of making the laminate. A method to produce cross-direction and multilayers of multi-material nanofibrous polymer using an electrospun technique is presented. The laminate can be used in a method where it is incorporated in a structure and provides stress information by scanning with an electromagnetic radiation to determine physical change within the structure. The nanofiber polymer provides electric conductivity information detected by electrochemical analyzer.

摘要: The present invention enables modification of an intraosseous implant device that is not only biologically non-inert, but can stimulate bone and vascular growth; decrease localized inflammation; and fight local infections. The method of the present invention provides a fiber with any of the following modifications: (1) Nanofiber with PDGF, (2) Nanofiber with PDGF+BMP2, and (3) Nanofiber with BMP2 and Ag. Nanofiber can be modified with other growth factors that have been shown to improve bone growth and maturation—BMP and PDGF being the most common. Nanofiber can be applied on the surface of the implant in several ways. First, a spiral micro-notching can be applied on the implant in the same direction as the threads with the nanofibers embedded into the notches. Second, the entire surface of the implant may be coated with a mesh of nanofibers. Third, it can be a combination of both embedding and notching.

摘要: The present invention implements a set of grooves/ridges created on Ti at the circumferential direction to increase surface area of implant in contact with bone. These grooves/ridges protect nanofiber matrix (NFM) made with Polycaprolactone (PCL) electrospun nanofiber (ENF) and collagen at the groove from physiological loading. Controlled fabrication of a ridge made with titanium nitride (TiN) around the circumference of Ti is provided using a plasma nitride deposition technique. PCL ENF may be deposited along the sub-micrometer grooves using the electrospin setup disclosed. The method provides for fabrication of microgroove on Ti using machining or TiN deposition and filling the microgrooves with the NFM. This method has proven through experimentation to be successful in increasing in vivo mechanical stability and promoting osseointegration on Ti implants. The immobilization of MgO NP and FN with the PCL-CG NFM on microgrooved Ti as provided in the invention optimizes biological performances of Ti.

摘要: The present invention provides a process by which both non-tissue engineered and tissue engineered cartilaginous-like structures can be fabricated. The process of the present invention provides a method to produce electrospun nanofiber-anchored NP gels. The present invention provides a functional design for novel engineered IVD. The present invention provides a method for fabrication of both non-tissue and tissue engineered IVDs. These cartilaginous-like structures can be used to produce replacements for degenerated natural IVD. The method of the present invention uses electrospun PCL nanofiber mesh to anchor the NP. The method of the present invention can create angle-ply AF structure around the circumference of NP to mimic the architecture of native IVD. The method of the present invention anchors the top and bottom sides of NP by using non-woven aligned or random nanofiber mesh to create scaffold for the generation of endplate (EP) tissue.

摘要: The present invention provides processes for combined applications of making grooves on an implant surface, applying MgO nanoparticles with PMMA cement, restricting the cement movement by PCL nanofiber and tethering biomolecules with PCL nanofiber to enhance mechanical stability and osseointegration of PMMA cement with bone. This is achieved through enhanced osteoconductive properties, roughness, and less viable fracture originating sites at the bone-cement interface. Such combined applications of nanoparticle and nanofiber on the mechanical stability and osseointegration of cemented implant is heretofore unknown, but as provided by the present invention can solve the debonding problem of cemented implant from bone.
