Article Citation - WoS: 44Citation - Scopus: 46A Rhodamine Based "turn-On" Chemodosimeter for Monitoring Gold Ions in Synthetic Samples and Living Cells(Royal Society of Chemistry, 2013) Emrullahoğlu, Mustafa; Karakuş, Erman; Üçüncü, MuhammedA rhodamine-based fluorescent probe, functionalized with an alkyne moiety, shows highly selective recognition towards Au(i) and Au(iii) ions over other metal ions. Probe 1 is successfully employed for the determination of residual gold species in synthetic samples and monitoring the accumulation of gold ions in living cells.Article Citation - WoS: 6Citation - Scopus: 6The Utilization of Ph Sensitive Spirocyclic Rhodamine Dyes for Monitoring D-Fructose Consumption During a Fermentation Process(Royal Society of Chemistry, 2013) Karakuş, Erman; Üçüncü, Muhammed; Eanes, Ritchie C.; Emrullahoğlu, MustafaThe colorimetric and fluorometric detection of d-fructose was achieved by employing a two component sensing system composed of an arylboronic acid as the host molecule and a pH sensitive spirocyclic rhodamine dye as the indicator molecule.Article Citation - WoS: 20Citation - Scopus: 23Rhodamine-Immobilised Electrospun Chitosan Nanofibrous Material as a Fluorescence Turn-On Hg2+ Sensor(John Wiley and Sons Inc., 2016) Horzum, Nesrin; Mete, Derya; Karakuş, Erman; Üçüncü, Muhammed; Emrullahoğlu, Mustafa; Demir, Mustafa MuammerA turn-on fluorescence sensing system for mercuric (Hg2+) ions relying on a modified rhodamine B–chitosan fluorophore moiety was developed. This novel sensing approach relies on the simultaneous electrospinning of chitosan and rhodamine B hydrazide with phenylisothiocyanate functionality in hexafluoroisopropanol solution at 3.4 kV cm−1. The electrospun mats exhibited not only considerably enhanced fluorescence intensity in the presence of mercury ions, a result attributed to the ring opening of the spirolactam unit of the rhodamine-based fluorophore, but also a remarkably high sensitivity and selectivity toward Hg2+. In effect, the strategy has the potential to open new avenues in the design and development of other high-performance nanofibrous sensing materials for detecting target metal species of environmental interest.
