Quantitation of acute monocytic leukemia cells spiked in control monocytes using surface-enhanced Raman spectroscopy
Surface enhanced Raman spectroscopy (SERS) was used to quantify leukemia cells spiked in control cells. The novelty consists of preparing cell lysates by ultrasound sonication and mixing with silver nanoparticles...
PublicationsDesign of a scalable AuNP catalyst system for plasmondriven photocatalysis
In this work we want to present a simple, fast and cost-efficient synthesis of a metal nanoparticle catalyst on glass support for plasmon driven heterogeneous photocatalysis. It is based on the efficient...
PublicationsA multidisciplinary approach in wetland geoarchaeology: Survey of the missing southern canal connection of the Fossa Carolina (SW Germany)
In this manuscript we document a multidisciplinary approach in wetland geoarchaeology for detecting artificial structures in a middle European floodplain. By means of a large set of different prospection...
PublicationsBetter than a lens – A novel concept to break the SNR-limit, given by Fermat’s principle
The signal in an incoherent imaging system gets transferred worse towards higher spatial frequencies. Since the photon noise is distributed equally in Fourier space, the signal‐to‐noise ratio (SNR)...
PublicationsOne-step reduced/quinone functionalized graphene oxide as reagentless lactate biosensing platform
One-step approach to simultaneously reduce and modify graphene oxide (GO) using N,N'-Bis(3,4-dihydroxybenzylidene)-1,2-diaminobenzene Schiff base ligand (3,4DHS), in order to obtain functionalized reduced...
PublicationsThe Staphylococcus aureus extracellular matrix protein (Emp) has a fibrous structure and bind
The extracellular matrix protein Emp of Staphylococcus aureus is a secreted adhes in that mediates interactions between the bacterial surface and extracellular host structures. However, its structure and...
PublicationsAn optical nanotrap array movable over a milimetre range
We present the theoretical and experimental study of nondiffracting Bessel beams as a device for optical manipulation and confinement of nanoparticles. We express analytically the optical forces acting...
PublicationsOptical forces generated by evanescent standing waves and their usage for sub-micron particle delivery
Recently a non-contact organization of sub-micron colloidal particles in the vicinity of liquid-solid interface attracted great attention in connection with the development of imaging techniques using...
PublicationsOptical conveyor belt for delivery of submicron objects
We demonstrate an optical conveyor belt that provides trapping and subsequent precise delivery of several submicron particles over a distance of hundreds of micrometers. This tool is based on a standing...
PublicationsA dual beam photonic crystal fiber trap for microscopic particles
The dual beam counterpropagating optical trap has found increased use in studies such as optical stretching, optical binding, Raman spectroscopy, and the trapping of high index particles. In this letter...
