Degradable starch nanoparticle assisted ethanol precipitation of DNA
Ip, Alexander C-F.; Tsai, Tsung Hao; Khimji, Imran; Huang, Po-Jung Jimmy; Liu, Juewen (Elsevier, 2014-04-18)Precipitation of DNA from a large volume of aqueous solution is an important step in many molecular biology and analytical chemistry experiments. Currently, this is mainly achieved by ethanol precipitation, where a long-term ... -
DNA duplex stabilization in crowded polyanion solutions
Khimji, Imran; Shin, Jeehae; Liu, Juewen (Royal Society of Chemistry, 2013-02-14)The melting temperature of duplex DNA is much higher in polyanions than in non-ionic polymers with similar ionic strength, suggesting an additional electrostatic contribution on top of the excluded volume effect. -
Extraction of DNA staining dyes from DNA using hydrophobic ionic liquids
Khimji, Imran; Doan, Krystina; Bruggeman, Kiara; Huang, Po-Jung Jimmy; Vajha, Puja; Liu, Juewen (Royal Society of Chemistry, 2013-05-18)The partition of oligonucleotides and DNA staining dyes into a few hydrophobic ionic liquids has been studied, where the oligonucleotides remain in the aqueous phase and all the DNA staining dyes are extracted in the ionic ... -
Visual optical biosensors based on DNA-functionalized polyacrylamide hydrogels
Khimji, Imran; Kelly, Erin Y.; Helwa, Youssef; Hoang, Michael; Liu, Juewen (Elsevier, 2013-12-15)Biosensors are devices that can provide quantitative or semi-quantitative analytical information about target molecules, where molecular recognition is based on biomolecular interactions. In recent years, DNA has emerged ...
