Spontaneously Forming Unilamellar Nano-Sized Vesicles – Polydispersity, Size, Shape and Stability
Nieh M-P, Raghunathan V.A., Huang C-Y, Pencer J., Harroun T., Katsaras J., National Research Council at Canada, CA
Unilamellar vesicles (ULV) made up entirely of biologically relevant materials can serve as carriers for drug delivery or gene therapy. Compared to extrusion and sonication methods, traditionally used for producing ULV, spontaneously forming ULV offer [...]
Molecular Communication among Nanomachines Using Vesicles
Molecular communication is a new and interdisciplinary research area that spans the nanotechnology, biotechnology, and communication technology. Molecular communication allows biological and artificially-created nanomachines to communicate over a short distance using molecules. In molecular communication, [...]
From Helical Starch Inclusion Complexes to Supramolecular Starch Assemblies
Starch, in particular the linear amylose fraction has the ability ot form helical inclusion complexes with suitable guest molecules like monoglycerides, linear alcohols, lactones or terpenes. The helical amylose segments have a strong tendency to [...]
Morphological Implications of the Interphase; Linking Crystalline and Amorphous Regions in Semi-Crystalline Polymers
In semi-crystalline polymers, a range of morphologies can be obtained in which a chain may traverse the amorphous region between the crystals or fold back into the crystals leading to adjacent or non-adjacent re-entry, depending [...]
Playing with actuators in microfluidic systems
In the lab-on a chips of the future, flows will be handled at the microscale through mazes of microchannels. For such systems, it will be crucial to integrate a number of actuators on the chip [...]
Effect of Surface Hydration and Interfusion of Suspended Silica Nanoparticles on Heat Transfer
Nanofluid suspensions enhance thermal conductivity and the heat transfer. The authors have previously shown that the Critical Heat Flux (CHF) of NiChrome wire in a silica nanofluid can be increased by 200% compared to conventional [...]
Controlled production of food emulsion using microfluidics
We present Microfluidic technology applied to the production of monodisperse emulsion in a food context. We investigate the effect of surfactants and microdevice geometry on drop size and robust production regimes. Minimum drop size achievable in [...]
Analytical Model for Magnetic Particle Transport in a Magnetically Biased Microfluidic System
An analytical model is described for predicting the transport and capture of magnetic micro/nano-particles in a magnetophoretic microsystem that consists of an array of integrated soft-magnetic elements embedded beneath a microfluidic channel. The elements are [...]
Integrated Microfluidic Device with an Electroplated Palladium Decoupler for Electrochemical Detection of the 8-hydroxydeoxyguanosine (8-OH-dG) DNA Adduct
More sensitive and reliable microfluidic devices are needed for the detection of the 8-hydroxy-deoxyguanosine (8-OH-dG) DNA adduct, one of the most frequently used biomarkers reporting on oxidative stress. Therefore, we have developed a capillary electrophoresis [...]
