Journal ArticleDOI
Development of highly luminescent and cytocompatible near-IR-emitting aqueous Ag2S quantum dots
Ibrahim Hocaoglu,M. Natali Cizmeciyan,Rengin Erdem,Can Ozen,Adnan Kurt,Alphan Sennaroglu,Havva Yagci Acar +6 more
TL;DR: In this paper, Colloidally stable and highly luminescent near-IR emitting Ag2S quantum dots (NIRQDs) were prepared by a simple aqueous method using 2-mercaptopropionic acid (2MPA) as a coating.
Journal ArticleDOI
Synthesis and characterization of poly(acrylic acid) stabilized cadmium sulfide quantum dots.
TL;DR: It is demonstrated that there is a critical COOH/Cd ratio that maximizes the photoluminescence intensity and quantum yield (QY) and above this critical ratio, which corresponds to smaller crystal sizes (3.7-4.1 nm) for each reaction set, the quantum yield decreases and the crystal size increases.
Journal ArticleDOI
Highly luminescent and cytocompatible cationic Ag2S NIR-emitting quantum dots for optical imaging and gene transfection
Fatma Demir Duman,Ibrahim Hocaoglu,Deniz Gulfem Ozturk,Devrim Gozuacik,Alper Kiraz,Havva Yagci Acar +5 more
TL;DR: These cationic Ag2S NIRQDs show a dramatic improvement in cytocompatibility even without PEGylation, a strong optical signal easily detected by confocal laser microscopy and effective conjugation and transfection of the green fluorescence protein plasmid to HeLa and MCF-7 cell lines (40% efficiency).
Journal ArticleDOI
RGDS-functionalized polyethylene glycol hydrogel-coated magnetic iron oxide nanoparticles enhance specific intracellular uptake by HeLa cells.
TL;DR: Findings indicate that the further biofunctional PEG hydrogel coating of MIONPs is a promising platform for enhanced specific cell targeting in biomedical imaging and cancer therapy.
Journal ArticleDOI
Emission tunable, cyto/hemocompatible, near-IR-emitting Ag2S quantum dots by aqueous decomposition of DMSA.
Ibrahim Hocaoglu,Fatma Demir,Özgür Birer,Alper Kiraz,Chantal Sevrin,Christian Grandfils,Havva Yagci Acar +6 more
TL;DR: Size tunable aqueous Ag2S quantum dots emitting in the near-infrared region were synthesized through decomposition of meso-2,3-dimercaptosuccinic acid in water and are effective optical imaging agents based on in vitro evaluation.
