Quantitative and Qualitative Examination of Particle-particle Interactions Using Colloidal Probe Nanoscopy

1Faculty of Pharmacy, University of Sydney, 2Department of Nanobiomedical Science & BK21 PLUS NBM Global Research Center for Regenerative Medicine, Dankook University


JoVE 51874

Colloidal probe nanoscopy can be used within a variety of fields to gain insight into the physical stability and coagulation kinetics of colloidal systems and aid in drug discovery and formulation sciences using biological systems. The method described within provides a quantitative and qualitative means to study such systems.

Quantitative Proteomics Using Reductive Dimethylation for Stable Isotope Labeling

1CEA, DSV, IG, Genoscope, 2CNRS-UMR8030, Évry, France, 3Université d'Évry Val d'Essonne, 4Massachusetts General Hospital Cancer Center


JoVE 51416

Stable isotope labeling of peptides by reductive dimethylation (ReDi labeling) is a rapid, inexpensive strategy for accurate mass spectrometry-based quantitative proteomics. Here we demonstrate a robust method for preparation and analysis of protein mixtures using the ReDi approach that can be applied to nearly any sample type.

Synthesis of Antiviral Tetrahydrocarbazole Derivatives by Photochemical and Acid-catalyzed C-H Functionalization via Intermediate Peroxides (CHIPS)

1Max-Planck-Institut fuer Kohlenforschung


JoVE 51504

A two-step procedure for the synthesis of pharmaceutically active indole-derivatives by C-H functionalization with anilines is described, using photo- and Brønsted acid catalysis.

Split-and-pool Synthesis and Characterization of Peptide Tertiary Amide Library

1Scripps Florida, The Scripps Research Institute


JoVE 51299

Peptide tertiary amides (PTAs) are a superfamily of peptidomimetics that include but are not limited to peptides, peptoids and N-methylated peptides. Here we describe a synthetic method which combines both split-and-pool and sub-monomer strategies to synthesize a one-bead one-compound library of PTAs.

Towards Biomimicking Wood: Fabricated Free-standing Films of Nanocellulose, Lignin, and a Synthetic Polycation

1Institute for Critical Technology and Applied Science, Virginia Tech, 2Macromolecules and Interfaces Institute, Virginia Tech, 3Institute for Food Safety and Health, Illinois Institute of Technology- Moffett Campus, 4Wood, Cellulose, and Paper Research Department, University of Guadalajara, 5Department of Sustainable Biomaterials, Virginia Tech, 6Sustainable Nanotechnology Interdisciplinary Graduate Education Program, Virginia Tech


JoVE 51257

The objective of this research was to form synthetic plant cell wall tissue using layer-by-layer assembly of nanocellulose fibrils and isolated lignin assembled from dilute aqueous suspensions.  Surface measurement techniques of quartz crystal microbalance and atomic force microscopy were used to monitor the formation of the polymer-polymer nanocomposite material.

In Situ SIMS and IR Spectroscopy of Well-defined Surfaces Prepared by Soft Landing of Mass-selected Ions

1Physical Sciences Division, Pacific Northwest National Laboratory


JoVE 51344

Soft landing of mass-selected ions onto surfaces is a powerful approach for the highly-controlled preparation of novel materials. Coupled with analysis by in situ secondary ion mass spectrometry (SIMS) and infrared reflection absorption spectroscopy (IRRAS), soft landing provides unprecedented insights into the interactions of well-defined species with surfaces.

Polymalic Acid-based Nano Biopolymers for Targeting of Multiple Tumor Markers: An Opportunity for Personalized Medicine?

1Nanomedicine Research Center, Department of Neurosurgery, Cedars-Sinai Medical Center


JoVE 50668

An example of a nano drug based on polymalic acid is presented towards the rational design of personalized medicine that is applicable to cancer. It describes the synthesis of a nano drug to treat Her2-positive human breast cancer in a nude mouse.

A Simple and Rapid Protocol for Measuring Neutral Lipids in Algal Cells Using Fluorescence

1Department of Chemical and Materials Engineering, University of Alberta, 2Department of Chemical and Petroleum Engineering, University of Calgary


JoVE 51441

A simple protocol to determine the neutral lipid content of algal cells using a Nile Red staining procedure is described. This time-saving technique offers an alternative to traditional gravimetric-based lipid quantification protocols. It has been designed for the specific application of monitoring bioprocess performance.

Amide Coupling Reaction for the Synthesis of Bispyridine-based Ligands and Their Complexation to Platinum as Dinuclear Anticancer Agents

1Faculty of Pharmacy, The University of Sydney, 2School of Science and Health, University of Western Sydney, 3Division of Chemistry and Environmental Science, School of Science and the Environment, Manchester Metropolitan University, 4Nature Publishing Group


JoVE 51740

This protocol describes the use of amide coupling reactions of isonicotinic acid and diaminoalkanes to form bridging ligands suitable for use in the synthesis of multinuclear platinum complexes, which combine aspects of the anticancer drugs BBR3464 and picoplatin.

Confocal Imaging of Confined Quiescent and Flowing Colloid-polymer Mixtures

1Chemical and Biomolecular Engineering Department, University of Houston


JoVE 51461

Confocal microscopy is used to image quiescent and flowing colloid-polymer mixtures, which are studied as model systems for attractive suspensions. Image analysis algorithms are used to calculate structural and dynamic metrics for the colloidal particles that measure changes due to geometric confinement.
