Polythiophene derivative on quartz resonators for miRNA capture and assay
Palaniappan, Al.; Cheema, Jamal Ahmed; Rajwar, Deepa; Ammanath, Gopal; Xiaohu, Liu; Seng Koon, Lim; Yi, Wang; Yıldız, Ümit Hakan; Liedberg, Bo (Royal Society of Chemistry, 2015-12)A novel approach for miRNA assay using a cationic polythiophene derivative, poly[3-(3′-N,N,N-triethylamino-1′-propyloxy)-4-methyl-2,5-thiophene hydrobromide] (PT), immobilized on a quartz resonator is proposed. The cationic ... -
Tailoring conformation-induced chromism of polythiophene copolymers for nucleic acid assay at resource limited settings
Rajwar, Deepa; Ammanath, Gopal; Cheema, Jamal Ahmed; Palaniappan, Alagappan; Yıldız, Ümit Hakan; Liedberg, Bo (American Chemical Society, 2016-04-20)Here we report on the design and synthesis of cationic water-soluble thiophene copolymers as reporters for colorimetric detection of microRNA (miRNA) in human plasma. Poly(3-alkoxythiophene) (PT) polyelectrolytes with ... -
Tuning pendant groups of polythiophene on carbon nanotubes for vapour classification
Tu, Meng-Che; Svm, Hari Krishna; Thilini, Alahakoon; Wallace, Lim Tse Loong; Moochhala, Shabbir; Yıldız, Ümit Hakan; Palaniappan, Al.; Liedberg, Bo (Elsevier, 2017)Poly(3-alkoxythiophene) (PT) with varying ratios of triethylamine and 1-methyl imidazole pendant groups and horizontally aligned single walled carbon nanotubes (SWCNT) are utilized in this study for volatile organic compounds ... -
Utilization of electrospun polystyrene membranes as a preliminary step for rapid diagnosis
Isık, Tuğba; Horzum, Nesrin; Yıldız, Ümit Hakan; Liedberg, Bo; Demir, Mustafa M. (Wiley, 2016-07)Recent advances in clinical practice drive deoxyribonucleic acid (DNA) as an important class of biomarker. Monitoring the change in their concentration suggests the initiation and/or progression of various disorders. ... -
Vapor phase solvatochromic responses of polydiacetylene embedded matrix polymers
Tu, Meng-Che; Cheema, Jamal Ahmed; Yıldız, Ümit Hakan; Palaniappan, Alagappan; Liedberg, Bo (Royal Society of Chemistry, 2017)The solvatochromic response of polydiacetylene (PDA) in the vapor phase is enabled upon incorporation with matrix polymers such as polyvinylpyrrolidone (PVP), polyethylene glycol (PEG), polyacrylic acid (PAA), and ... -
Visual detection of Al3+ ions using conjugated copolymer-ATP supramolecular complex
Tu, Meng-Che; Rajwar, Deepa; Ammanath, Gopal; Alagappan, Palaniappan; Yıldız, Ümit Hakan; Liedberg, Bo (Elsevier, 2016-03)A colorimetric Al3+ sensor based on fluorescence recovery of a conjugated copolymer-ATP complex is proposed. An optimized ratio of two polythiophene (PT) monomers is utilized to synthesize copolymer (CP) that yielded ...
