  1. 1. Small-Scale Sample Handling for Studies of Liquid Crystals and Lipid-Based Soft Matter

    Författare :Gabriel Ohlsson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fluorescence microscopy; nanocell; Microfluidics; aquaporins; liquid crystals; membrane transport; phase transitions; QCM-D; soft matter; lipid bilayer;

    Sammanfattning : In the field of sensing in general and biosensing in particular, there is a growing need for integratingminiaturised senor elements in microfluidic systems. The advantages are several, some of which being that the consumption of, often very expensive, sample material can be reduced; sampleexchange can be optimized; sensor performance in terms of detection limits can be improved and phenomena occurring on a very small, and even single-molecule, scale can be studied.

  2. 2. Sample handling in nanoscale chemistry

    Författare :Erik Litborn; KTH; []
    Nyckelord :;

    Sammanfattning : Miniaturization is a strong on-going trend within analyticalchemistry. This has led to an increased demand for newtechnologies allowing smaller volumes of samples as well asreagents to be utilized. This thesis deals with the use of openchip-based reactors (vials); a concept that offers an increasedflexibility compared to the use of closed reactors. LÄS MER
