Polymer Microarrays for High Throughput Discovery of Biomaterials
1Laboratory of Biophysics and Surface Analysis, University of Nottingham , 2School of Molecular Medical Sciences, University of Nottingham , 3David H. Koch Institute for Integrative Cancer Research, Massachusetts Institute of Technology
A description of the formation of a polymer microarray using an on-chip photopolymerization technique. The high throughput surface characterization using atomic force microscopy, water contact angle measurements, X-ray photoelectron spectroscopy and time of flight secondary ion mass spectrometry and a cell attachment assay is also described.
Isolation and Biophysical Study of Fruit Cuticles
1Department of Chemistry, City College of New York, City University of New York Graduate Center and Institute for Macromolecular Assemblies, 2Department of Chemical Engineering, City College of New York
Aerial plant organs are protected by the cuticle, a supramolecular biopolyester-wax assembly. We present protocols to monitor selective removal of epi- and intracuticular waxes from tomato fruit cuticles on molecular and micro scales by solid-state NMR and atomic force microscopy, respectively, and to assess the cross-linking capacity of engineered cuticular biopolyesters.
Magnetic Resonance Elastography Methodology for the Evaluation of Tissue Engineered Construct Growth
1Department of Biological Systems Engineering, University of Nebraska-Lincoln, 2Department of Engineering Mechanics, University of Nebraska-Lincoln
The procedure demonstrates the methodology of magnetic resonance elastography for monitoring the engineered outcome of adipose and osteogenic tissue engineered constructs through noninvasive local assessment of the mechanical properties using microscopic magnetic resonance elastography (μMRE).
Isolation and Characterization of Dendritic Cells and Macrophages from the Mouse Intestine
1Department of Pediatrics, Emory University, 2Department of Pathology & Laboratory Medicine, Emory University
Here, we detail a methodology for the rapid isolation of mouse intestinal dendritic cells (DCs) and macrophages. Phenotypic characterization of intestinal DCs and macrophages is performed using multi-color flow cytometric analysis while magnetic bead enrichment followed by cell sorting is used to yield highly pure populations for functional studies.
Alginate Hydrogels for Three-Dimensional Organ Culture of Ovaries and Oviducts
Medicinal Chemistry and Pharmacognosy, University of Illinois at Chicago
Culture of normal cells in their three-dimensional context represents an alternative method to study early events required for cellular transformation and tumorigenesis. This method is used to grow normal ovarian and oviductal cells to study early events in ovarian cancer formation.
Immuno-fluorescence Assay of Leptospiral Surface-exposed Proteins

An efficient method to assess surface-exposure of leptospiral proteins is described. The method is specifically designed to avoid disruption of the fragile outer membrane of leptospiral cells. This technique requires employment of several negative controls to assess the integrity of the outer membrane and specificity of antibody reaction.
Plasma Lithography Surface Patterning for Creation of Cell Networks
1Aerospace and Mechanical Engineering, University of Arizona , 2Biomedical Engineering IDP and BIO5 Institute, University of Arizona
A versatile plasma lithography technique has been developed to generate stable surface patterns for guiding cellular attachment. This technique can be applied to create cell networks including those that mimic natural tissues and has been used for studying several, distinct cell types.
Microfabricated Platforms for Mechanically Dynamic Cell Culture
1Department of Mechanical and Industrial Engineering, University of Toronto, 2Institute of Biomaterials and Biomedical Engineering, University of Toronto, 3Faculty of Dentistry, University of Toronto
In this protocol, we demonstrate the fabrication of a microactuator array of vertically displaced posts on which the technology is based, and how this base technology can be modified to conduct high-throughput mechanically dynamic cell culture in both two-dimensional and three-dimensional culture paradigms.
Simultaneous Synthesis of Single-walled Carbon Nanotubes and Graphene in a Magnetically-enhanced Arc Plasma
Department of Mechanical and Aerospace Engineering, The George Washington University
Anodic arc discharge is one of the most practical and efficient methods to synthesize various carbon nanostructures. To increase the arc controllability and flexibility, a non-uniform magnetic field was introduced to process the one-step synthesis of large-scale graphene flakes and high-purity single-walled carbon nanotubes.
Formulation of Diblock Polymeric Nanoparticles through Nanoprecipitation Technique
