Biofunctional quantum dots as fluorescence probe for cell-specific targeting

Ag, Didem; Bongartz, Rebecca; Dogan, Leyla Eral; Seleci, Muharrem; Walter, Johanna-Gabriela; Demirkol, Dilek Odaci; Stahl, Frank; Ozcelik, Serdar; Timur, Suna; Scheper, Thomas (Amsterdam : Elsevier, 2014)

We describe here the synthesis, characterization, bioconjugation, and application of water-soluble thioglycolic acid TGA-capped CdTe/CdS quantum dots (TGA-QDs) for targeted cellular imaging. Anti-human epidermal growth ...
Cancer cell-selective, clathrin-mediated endocytosis of aptamer decorated nanoparticles

Engelberg, Shira; Modrejewski, Julia; Walter, Johanna-Gabriela; Livney, Yoav D.; Assaraf, Yehuda G. (S.l. : Impact Journals LLC, 2018)

Lung cancer is the leading cause of cancer mortality worldwide, resulting in 88% deaths of all diagnosed patients. Hence, novel therapeutic modalities are urgently needed. Single-stranded oligonucleotide-based aptamers ...
Homodyne spin noise spectroscopy and noise spectroscopy of a single quantum dot

Sterin, Pavel (Hannover : Institutionelles Repositorium der Gottfried Wilhelm Leibniz Unviersität Hannover, 2023)

The steady-state fluctuations of a spin system are closely interlinked with its dynamics in linear response to external perturbations. Spin noise spectroscopy exploits this link to extract parameters characterizing the ...
Kontrolle zeitaufgelöster Einzelelektronen-Tunnelprozesse in einem Quantenpunkt

Wagner, Timo (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)

In dieser Arbeit werden zwei verschiedene experimentelle Ansätze untersucht, die stochastischen Fluktuationen (Schrotrauschen) zwischen den Einzelelektronen-Tunnelereignissen in einem Quantenpunkt zu kontrollieren. Die ...
Multiphoton microscopy of transdermal quantum dot delivery using two photon polymerization-fabricated polymer microneedles

Gittard, Shaun D.; Miller, Philip R.; Boehm, Ryan D.; Ovsianikov, Aleksandr; Chichkov, Boris; Heiser, Jeremy; Gordon, John; Monteiro-Riviere, Nancy A.; Narayan, Roger J. (Cambridge : Royal Society of Chemistry, 2011)

Due to their ability to serve as fluorophores and drug delivery vehicles, quantum dots are a powerful tool for theranostics-based clinical applications. In this study, microneedle devices for transdermal drug delivery were ...
Nanostrukturierte Graphendevices

Müller, André (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2015)

Nonequilibrium spin noise spectroscopy on single quantum dots

Wiegand, Julia Susan (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)

All optical spin noise spectroscopy is typically used to extract the virtually undisturbed spin dynamics from measurements of spin fluctuations in thermal equilibrium. In this thesis, the method is applied to study spin ...
Phonons in InAs/AlAs single quantum dots observed by optical emission

Sarkar, D.; Van Der Meulen, H.P.; Calleja, J.M.; Becker, J.M.; Haug, Rolf J.; Pierz, Klaus (College Park, MD : American Physical Society, 2005)

Photoluminescence emission spectra of self-assembled single InAs/AlAs quantum dots with variable size reveal typical sharp lines below 1.8 eV, corresponding to transitions between fully confined states. Above this energy ...
Rausch- und Transportmessungen an Einzel- und Doppelquantenpunkten

Kühne, Jan Klaus (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)

In dieser Arbeit wird das resonante Tunneln durch selbstorganisierte InAs Quantenpunkte auf seine Transport- und Rauscheigenschaften untersucht. Wechselwirkungseffekte, wie die Coulomb-Blockade oder die Fermikantensingularität ...
Transferrin-decorated niosomes with integrated inp/zns quantum dots and magnetic iron oxide nanoparticles: Dual targeting and imaging of glioma

Seleci, Didem Ag; Maurer, Viktor; Barlas, Firat Baris; Porsiel, Julian Cedric; Temel, Bilal; Ceylan, Elcin; Timur, Suna; Stahl, Frank; Scheper, Thomas; Garnweitner, Georg (Basel : MDPI, 2021)

The development of multifunctional nanoscale systems that can mediate efficient tumor targeting, together with high cellular internalization, is crucial for the diagnosis of glioma. The combination of imaging agents into ...
Vertikaler Ladungstransport über nulldimensionale Zustände in Doppelbarrieren-Heterostrukturen

Agafonov, Alexei B. (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2011)
