   Sammanfattning : Photonic integrated circuits (PICs) combine hundreds of optical components on a chip, and can enable fast communications, high-performance computing, and improved sensing. PICs, made by miniaturized optical waveguides, require many reconfigurable elements to enable programmable functionalities and to compensate for fabrication variations and environmental factors.

   Sammanfattning : Ink-jet printing offers an ideal answer to the emerging trends and demands of depositing at ambient temperatures picoliter droplets of oxide solutions into functional thin films and device components with a high degree of pixel precision. It is a direct single-step mask-free patterning technique that enables multi-layer and 3D patterning. LÄS MER

7. 15. Ultra-sensitive measurements of magnetically labelled RCA products in a microfluidic channel using a high-Tc SQUID

   Författare :Sobhan Sepehri; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diagnostics.; high-Tc SQUID; biosensor; magnetic nanoparticle; rolling circle amplification; magnetic bioassay;

   Sammanfattning : The development of a nucleic acid (deoxyribonucleic acid (DNA), ribonucleic acid (RNA)) bioassay based on magnetic nanoparticles (MNPs) with a high-Tc superconducting quantum interference device (SQUID) gradiometer as a magnetic readout is described. The specific binding of the MNPs to the target DNA molecules changes the MNPs size distribution and, therefore, the relaxation dynamics and is measured by magnetic ac susceptometry. LÄS MER
