    Get PDF
    The Microfluidics and Nanofluidics Handbook: Two-Volume Set comprehensively captures the cross-disciplinary breadth of the fields of micro- and nanofluidics, which encompass the biological sciences, chemistry, physics and engineering applications. To fill the knowledge gap between engineering and the basic sciences, the editors pulled together key individuals, well known in their respective areas, to author chapters that help graduate students, scientists, and practicing engineers understand the overall area of microfluidics and nanofluidics. Topics covered include Finite Volume Method for Numerical Simulation Lattice Boltzmann Method and Its Applications in Microfluidics Microparticle and Nanoparticle Manipulation Methane Solubility Enhancement in Water Confined to Nanoscale Pores Volume Two: Fabrication, Implementation, and Applications focuses on topics related to experimental and numerical methods. It also covers fabrication and applications in a variety of areas, from aerospace to biological systems. Reflecting the inherent nature of microfluidics and nanofluidics, the book includes as much interdisciplinary knowledge as possible. It provides the fundamental science background for newcomers and advanced techniques and concepts for experienced researchers and professionals

    Development of collagen scaffolds to address biomechanical design criteria for tendon鈥搕o鈥揵one repair

    The tendon-bone junction (TBJ) is a unique, mechanically dynamic and structurally graded anatomical zone which transmits tensile loads between tendon and bone. The TBJ repeatedly transmits high tensile loads to result in movement without failure by effectively dissipating stress concentrations which arise between mechanically dissimilar materials (tendon, bone). Upon injury, surgical repair techniques rely on mechanical fixation, and the local heterogeneities of the TBJ do not reform, causing poor functional outcomes (re-failure >90%). Biomaterial platforms and tissue engineering methods offer an alternative approach to address these injuries. Although current methods are moving towards multi-tissue regenerative approaches to address these injuries, it remains a challenge to fully characterize local mechanical and cellular heterogeneities within a single biomaterial using traditional techniques. Herein we describe a variety of collagen biomaterials which incorporate local changes and patterns in composition to create multi-compartment and composite scaffolds for the purpose of orthopedic regeneration. We demonstrate that these biomaterials exhibit enhanced, locally tunable mechanical properties, and are capable of providing mesenchymal stem cells (MSCs) signals in a spatially selective manner. We highlight tradeoffs and synergies in local cellular and mechanical behavior, which give rise to the mechanisms behind observed differences in bulk cellular and biomaterial behavior. This work provides key insights into design elements under consideration for mechanically competent, multi-tissue biomaterial platforms which drive MSCs towards spatially distinct lineages for orthopedic regeneration
