Nanoscale structure of type I collagen fibrils: Quantitative measurement of D‐spacing
(WILEY‐VCH Verlag, 2013-01)
This article details a quantitative method to measure the D‐periodic spacing of type I collagen fibrils using atomic force microscopy coupled with analysis using a two‐dimensional fast fourier transform approach. Instrument ...
Polymeric Scaffolds for Bone Tissue Engineering
(Kluwer Academic Publishers-Plenum Publishers; Biomedical Engineering Society ; Springer Science+Business Media, 2004-03)
Bone tissue engineering is a rapidly developing area. Engineering bone typically uses an artificial extracellular matrix (scaffold), osteoblasts or cells that can become osteoblasts, and regulating factors that promote ...
Intracortical Neural Probes with Post-Implant Self-Deployed Electrodes for Improved Chronic Stability.
(2015)
This thesis presents a new class of implantable intracortical neural probe with small recording electrodes that deploy away from a larger main shank after insertion. This concept is hypothesized to enhance the performance ...
Fabrication and in vitro testing of polymeric delivery system for condensed DNA
(Wiley Subscription Services, Inc., A Wiley Company, 2003-12-15)
Polyethylenimine (PEI) was combined with plasmid DNA and freeze dried following the addition of sucrose as a lyoprotectant and pore-forming agent. Freeze-dried PEI DNA condensates were dry mixed with granular polylactideglycolic ...
Poly(glutamic acid) poly(ethylene glycol) hydrogels prepared by photoinduced polymerization: Synthesis, characterization, and preliminary release studies of protein drugs
(Wiley Subscription Services, Inc., A Wiley Company, 2002-10)
A class of new biodegradable hydrogels based on poly(ethylene glycol) methacrylate-graft-poly(glutamic acid) and poly(ethylene glycol) dimethacrylate was synthesized by photoinduced polymerization. Because all the polymeric ...
On the Fatigue Life of the Human Anterior Cruciate Ligament: Experimental Studies of the Effects of Limited Internal Femoral Rotation and Microscopic Entheseal Anatomy.
(2015)
Anterior cruciate ligament (ACL) injuries pose significant health and financial burdens, such as the early development of knee osteoarthritis. It is imperative to better prevent these injuries, but several knowledge gaps ...
Room-temperature preparation and characterization of poly (ethylene glycol)-coated silica nanoparticles for biomedical applications
(Wiley Subscription Services, Inc., A Wiley Company, 2003-09-15)
Monodisperse, spherical, polyethylene glycol (PEG)–coated silica nanoparticles have been prepared at room temperature and characterized for the purpose of biomedical applications. The particles were synthesized by the ...
Effects of pH on human bone marrow stromal cells in vitro : Implications for tissue engineering of bone
(Wiley Subscription Services, Inc., A Wiley Company, 2002-05)
The objective of this study was to address the hypothesis that changes in extracellular pH alter collagen gene expression, collagen synthesis, and alkaline phosphatase activity in bone marrow stromal cells (BMSCs). Potential ...
Conducting polymers grown in hydrogel scaffolds coated on neural prosthetic devices
(Wiley Subscription Services, Inc., A Wiley Company, 2004-12-15)
The conducting polymer polypyrrole (PPy) was electrochemically grown on hydrogel scaffolds deposited on the surface of microfabricated neural prosthetic devices. It is shown that the pyrrole monomer can be grown vertically ...
Cu 2+ Removal and recovery by Spi SORB: batch stirred and up-flow packed bed columnar reactor systems
(Springer-Verlag, 2006-02-23)
The biosorption of Cu 2+ by free and poly acrylamide gel (PAG) immobilized Spirulina platensis ( Spi SORB) was characterized under batch and continuous packed bed columnar reaction systems. The biosorption of Cu 2+ was ...
