3d Capillary Valves for Versatile Capillary Patterning of Channel Walls
نویسندگان
چکیده
We demonstrate passive capillary patterning of channel walls with a liquid in situ. Patterning is performed using a novel 3D capillary valve system combining three standard capillary stop valves. A range of different patterns is demonstrated in three channel walls. Capillary patterning was designed for precise in situ patterning of phase-change materials (e.g. UV curable hydrogels, gels, resins), but may find further applications such as local surface functionalization.

3D study of capillary network derived from human cord blood mesenchymal stem cells and differentiated into endothelial cell with VEGFR2 protein expression
New blood forming vessels are produced by differentiation of mesodermal precursor cells to angioblasts that become endothelial cells (ECs) which in turn give rise to primitive capillary network. Human cord blood (HCB) contains large subsets of mononuclear cells (MNCs) that can be differentiated into endothelial-like cells in vitro. Human mononuclear progenitor cells were purified from fresh umb...
متن کاملSpinal Intradural Extramedulary Capillary Hemangioma Mimicking Meningioma
Hemangiomas are considered as vascular malformations which are categorized by the type of vascular channel to capillary, cavernous, venous or arteriovenous(1). Their usual locations are soft tissue , cutaneous or subcutaneous tissue and bone especially vertebra(2).However, intradural extramedullary hemangiomas are rare and most of them fall in cavernous type category. Hereby, authors report a w...
متن کاملThe Extent of the Capillary Bed of the Heart
By means of injections made into the coronary arteries of beating hearts it has been possible to determine the number of capillaries in the normal heart muscle. This study has shown a very rich blood supply with an average of approximately one capillary for each muscle fibre in the ventricular walls and papillary muscles, and a less abundant supply in the auricular muscle and Purkinje system. T...
متن کاملSingle-step Capillary Electrophoresis for Field-amplified Sample Stacking
We developed a novel single-step capillary electrophoresis (SSCE) scheme for field-amplified sample stacking (FASS) by using a hydrophilic material polymethyl methacrylate (PMMA) microchannel chip. The capillary effect was used to introduce liquids and control capillary stop valves in a partial barrier structure of the microchannel. Through the combined action of stop valves and air vents, both...
متن کاملMicrofabrication inside capillaries using multiphase laminar flow patterning
The reaction of species in solutions flowing laminarly (without turbulent mixing) inside capillaries was used as the basis for a broadly applicable method of microfabrication. In this method, patterning occurs as a result of transport of reactive species to interfaces within the capillary by laminar flow. A wide range of chemistries can be used to generate structures with feature sizes of less ...
