In this research, we demonstrated a microfluidic chip to pretreat the samples for viral genome assay. The microfluidic chip has the following three functions; (1) Virus purification and enrichment, (2) Viral RNA extraction, and (3) Capture of the targeted virus genome. Hydroxyapatite chromatography, Boom method, and PNA (Peptide Nucleic Acid) were used for the above three functions, respectively....
We have synthesized novel Mussel-mimetic glues (adhesive polymer) from plant-derived monomers. Because the adhesive polymer contains catechol group at their chain ends, which is similar chemical structure of 3,4- dihydroxyphenyl-L-alanine (dopa) produced by Mussel, it demonstrated strong adhesive characteristics onto organic and/or inorganic surfaces beyond instant super glue. The origin of this strong...
pH sensors are used for measuring pH of solutions etc in the beaker. It measures the whole part of samples collected inside the container. They are mostly made by a glass electrode method. Its merits are that has good potential reproducibility, and potential equilibrium time is faster than other pH measuring methods. pH sensors made by the glass electrode method are composed of glass electrode which...
We have succeeded in protein crystallization and processing by electrically-induced bubble knife. The dispensed directional mono-dispersed micro-bubbles whose air-liquid interface tends to combine the ambient molecules due to by their stiction force on the surface of micro-bubbles. Electrically-induced bubble knife enables to generate mono-dispersed micro-bubbles by the electrolysis and local heat,...
Recently, miniaturization of optical components becomes one of the most attractive subjects in the optics industry, by combining multiple optical functions into single optical components with microstructures. The mold to produce those optical components is required to be able to be machined to desired microstructures with high precision on the surface. Since the existing machining methods are either...
Magnetic hydrogel microbeads have wide applications in the fields of biological engineering and regenerative medicine. In the paper, we proposed a new method for fabricating the magnetic hydrogel beads by encapsulating the magnetic resonance imaging (MRI) contrast media inside the polyethylene glycol diacrylate (PEGDA) solution. Then a microfluidic device was prepared for crosslinking the magnetic...
