Surface enhanced Raman spectroscopy and microfluidic platforms: challenges, solutions and potential applications

The exhaustive body of literature published in the last four years on the development and application of sytems based on surface enhanced Raman spectroscopy (SERS) combined with microfluidic devices demonstrates...

Tailoring Cellular Uptake and Fluorescence of Poly(2-oxazoline)-Based Nanogels

Controlling the size and charge of nanometersized objects is of upmost importance for their interactions with cells. We herein present the synthesis of poly(2-oxazoline) based nanogels comprising a hydrophilic...

On-Chip spectroscopic assessment of microbial susceptibility to antibiotics within 3 hours

In times of rising antibiotic resistances, there is a high need for fast, sensitive and specific methods to determine antibiotic susceptibilities of bacterial pathogens. Here, we present an integrated...

A new family of field-stable and highly sensitive SQUID current sensors based on sub-micrometer cross-type Josephson junctions

We report on the development of a new family of SQUID current sensors based on submicron cross-type Josephson tunnel junctions. Their low total junction capacitance permit high usable voltage swings of...

Raman and Infrared Spectroscopy Distinguishing Replicative Senescent from Proliferating Primary Human Fibroblast Cells by Detecting Spectral Differences Mainly Due to Biomolecular Alterations

Cellular senescence is a terminal cell cycle arrested state, assumed to be involved in tumor suppression. We studied four human fibroblast cell strains (BJ, MRC-5, IMR-90, and WI-38) from proliferation...

Application and fabrication aspects of sub-micrometer-sized Josephson junctions

We present the description of two methods for the fabrication of sub-micron sized Josephson junctions, namely the shadow-evaporation technique and the cross-type technology. Their importance for the field...

Self-organized growth of germanium nanocolumns

The crystalline germanium nanostructures were obtained on silicon surface by chemical vapor deposition technique using a germanium (IV) iso-propoxide ([Ge(OiPr)4]) metalorganic precursor as a germanium...

Fiber Fabry-Perot Interferometer for Curvature Sensing

A curvature sensor based on a Fabry-Perot (FP) interferometer is proposed. A capillary silica tube is fusion spliced between two single mode fibers, producing an FP cavity. Two FP sensors with different...

Bacterial community and PHB-accumulating bacteria associated with the wall and specialized niches of the hindgut of the forest cockchafer (Melolontha hippocastani)

A characterization of the bacterial community of the hindgut wall of two larval and the adult stages of the forest cockchafer (Melolontha hippocastani) was carried out using amplicon sequencing of the...
