This paper presents a microfluidic device for magnetophoretic separation of red blood cells from blood under continuous flow.
The separation method consists of continuous flow of a blood sample (diluted in PBS) through a microfluidic channel which
presents on the bottom “dots” of ferromagnetic layer. By applying a magnetic field perpendicular on the flowing direction,
the ferromagnetic “dots” generate a gradient of magnetic field which amplifies the magnetic force. As a result, the red blood
cells are captured on the bottom of the microfluidic channel while the rest of the blood is collected at the outlet. Experimental
results show that an average of 95% of red blood cells is trapped in the device. 相似文献

Polyphosphonates, polyphosphates, polyarylazophosphonates and polyarylazophosphates were synthesized by a new alternative to the classical phase transfer catalysis, respectively, the modified inverse phase transfer catalysis (IPTC) polycondensation of various phenylphosphonic (phosphoric) dichlorides (phenylphosphonic dichloride, phenylphosphoric dichloride, p-chlorophenylphosphoric dichloride) with bisphenols: bisphenol A, tetrabromobisphenol A, bis-(4-hydroxyphenyl)methane (bisphenol F), 4,4′-dihydroxyazobenzene. The polymers were characterized by infrared spectroscopy and magnetic resonance (1H-NMR, 31P-NMR, 13C-NMR) spectroscopy. Yields in the range of 63.5–85% and molecular weights (M w) of ~2,000–8,200 g mol?1 were obtained. Polyphosphonates were stable up 210–270 °C and polyphosphates up 190–220 °C in air atmosphere. For a correct estimation of the thermal behavior of similar compounds, a kinetic analysis using a modified version of Non Parametric Kinetic method for representative polyphosphonate and polyphosphate was realized. The studies made on the hydrolytic degradation of the synthesized polyphosphates show that the most stable polymer under alkali-catalyzed degradation is the polyphosphate obtained by IPTC of phenylphosphoric dichloride and bisphenol A. 相似文献

Organic–inorganic hybrids obtained by in situ polymerization of aniline in silica/phosphonate matrix
Nicoleta Plesu Gheorghe Ilia Paula Sfirloaga Smaranda Iliescu 《Journal of Materials Science》2009,44(23):6437-6446
A method for preparing organic–inorganic hybrids containing organophosphorus compounds, silica, and polyaniline (PANI) was
developed using sol–gel technique. This method allows the in situ synthesis of organic–inorganic hybrids by reacting tetraethoxysilane
(TEOS), aniline, initiator, organophosphorus compound in formic acid. The formic acid has multiple functions: as solvent and
acidic media for polymerization of aniline and reagent for sol–gel process. The use of an organophosphorus compound as coupling
agent and the introduction of a conductive polymer in silica matrix was investigated. 相似文献

The paper presents a dielectrophoretic chip, fully enclosed, with bulk silicon electrodes fabricated using wafer-to-wafer bonding techniques and packaged at the wafer level. The silicon electrodes, which are bonded to two glass dies, define in the same time the walls of the microfluidic channel. The device is fabricated from a silicon wafer that is bonded (at wafer level) anodically and using SU8 photoresist between two glass wafers. The first glass die includes drilled holes for inlet/outlet connections while the second glass die assure the electrical connections, through via holes and a metallization layer, between the silicon electrodes and a printing circuit board. 相似文献
