A gas-diffusion gold-ring tip: Fabrication, characterization, and application in Electrocatalysis
(Elsevier Science Inc, 2009-07)
A gas-diffusion gold-ring microelectrode used as scanning electrochemical microscopy tip was fabricated. Compared to the ring-tip for droplet dispensation reported before, the as sa-fabricated micropipette tip has a larger ...
Fabrication and characterization of glass micropipettes: Exploration of use as single-cell manipulation and bioprinting tips
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2022-12-06)
Micropipettes are primarily used for cell transfection procedures (microinjection). However, their use has been limited to cells larger than 25 µm in diameter. Alternatively, nanopipettes have been shown to enable the ...
Disposable micropipette tip for purifying DNA fragments
(Korean Soc Biotechnology & Bioengineering, 2020-04-23)
A novel functional micropipette tip for DNA purification, called DNAtip, is described based on a novel coating process. The functional layer is prepared by an internal coating with silica particles supported into a polyvinyl ...
Spectrophotometric determination of dithizone-mercury complex by solid phase microextraction in micropipette tip syringe packed with activated carbon xerogel
(Elsevier Science, 2016-11)
A new simple miniaturized solid phase microextraction system in a syringe was developed for mercury (Hg) preconcentration of in water samples based on the adsorption of its dithizone complex on a microcolumn. The syringe ...
Construção e caracterização de micro-células voltamétricas para análises em volumes reduzidosConstruction and characterization of voltammetric micro-cells to analyses in reduced volumes

A simple vitrification technique for sheep and goat embryo cryopreservation
(Elsevier Science, 2011-01)
The aim of this study was to evaluate pregnancy and embryo survival rate of vitrified in vivo produced Merino sheep and Criolla goat (morulae and blastocysts) embryos, using the plastic tips of micropipettes, as containers ...
Interaction between a laminar starting immersed micro-jet and a parallel wall
(American Institute of Physics, 2015-01)
In the present work, we study the starting transient of an immersed micro-jet in close vicinity to a solid wall parallel to its axis. The experiments concern laminar jets (Re < 200) issuing from a 100 μm internal tip ...
Scanning Electrochemical Microscopy. 55. Fabrication and Characterization of Micropipet Probes
(American Chemical Society, 2005-08)
The fabrication and characterization of novel micropipette probes for use in scanning electrochemical microscopy (SECM) are described. These can be used to dispense small (pL) amounts of a solution while monitoring the ...

Vitrified embryo transfer in Merino sheep under extensive conditions
(Colégio Brasileiro de Reproducao Animal, 2019-06)
The aim was to evaluate pregnancy success after transfer of embryos vitrified in micropipette tips in Merino sheep under extensive conditions. A second objective was to evaluate the influence of embryo stage in such pregnancy ...
