Discretely tunable Tm-doped fiber-based MOPA using FBG arrays as spectral filters

Over the past years, Thulium (Tm) -doped fiber lasers in the 2μm region have gained a lot of interest due to many potential applications in materials processing and biophotonics. Based on the broad gain...

Process flow to integrate nanostructures on silicon grass in surface micromachined systems

The process flow to integrate metallic nanostructures in surface micromachining processes is presented. The nanostructures are generated by evaporation of microstructured silicon grass with metal. The...

Synthesis and solution stability of water-soluble κ2N,κO-bis(3,5-dimethylpyrazolyl)ethanol manganese(I) tricarbonyl bromide (CORM-ONN1)

The reaction of (OC)5MnBr with bis(3,5-dimethyl-1-pyrazolyl)methane yields [{(PzMe2)2CH2}Mn(CO)3Br](1). The use of tridentate heteroscorpionates such as bis(3,5-dimethyl-1-pyrazolyl)acetic acid and 2,2-bis(3,5-dimethyl-1-pyrazolyl)ethanol...

Tip-enhanced Raman scattering for tracking of invasomes in the stratum corneum

Stratum corneum is the primary skin barrier to percutaneous absorption. Since 1980, topical liposomal formulations have been proposed and successfully employed for increasing the drug penetration through...

Chemical-Mechanically Planarized Cross-Type Josephson Junctions in Nb-Al-AlOx-Nb Technology

Fabrication of devices composed of Josephson junctions in trilayer technology is usually compromised by the topography of the subjacent layers. If the structures of subsequent layers traverse steps, several...

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...
