  1. 6. Fabrication and Optimization of a Nanoplasmonic Chip for Diagnostics

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jonas Segervald; [2019]
    Keywords : AFM; NIL; SPR; SERS; nanohole; nanohole array; nanoimprint lithography; physical vapor deposition; plasma treatment; plasmonic; plasmons; surface plasmon resonance; localized surface plasmon resonance; metal enhanced fluoresence; surface enhanced raman spectroscopy; transmittance; nanoplasmonic; signal enhancement;

    Abstract : To increase the survival rate from infectious- and noncommunicable diseases, reliable diagnostic during the preliminary stages of a disease onset is of vital importance. This is not trivial to achieve, a highly sensitive and selective detection system is needed for measuring the low concentrations of biomarkers available. READ MORE

  3. 7. Study of ohmic contact formation on AlGaN/GaN heterostructures

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Kai-Hsin Wen; [2019]
    Keywords : ohmic contacts; wide bandgap; Ta-based; recess etch; N-vacancies;

    Abstract : It is challenging to achieve low-resistive ohmic contacts to III-nitride semiconductors due to their wide bandgap. A common way to reduce the contact resistance is to recess the ohmic area prior to metallization. READ MORE

  4. 8. μLEDs for optogenetics

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Lukas Wendt; [2018]
    Keywords : μLED; microLED; optogenetics; nitrides; platelets; LNL; epilepsy; Technology and Engineering;

    Abstract : Optogenetics is unfolding new ways for us to study the nervous system and could one day be a standard approach to treat neurological diseases like epilepsy. To selectively study the effects on a subcellular level, microscopic light sources are needed. READ MORE

  5. 9. Patterned Nanocomposite of Carbon Nanotube/Polymer

    University essay from Umeå universitet/Institutionen för fysik

    Author : Saeed Motaragheb Jafarpour; [2017]
    Keywords : ;

    Abstract : Single walled carbon nanotubes (SWCNTs) are carbon based nanostructures with extraordinary electronical and mechanical properties. They are used in a wide range of applications, usually embedded in polymer as fillers to form polymer based nanocomposites, in order to affect the electronic behavior of the polymer matrix.

  6. 10. Fabrication and characterization of nano/micrometer glass channels with UV lithography

    University essay from Uppsala universitet/Mikrosystemteknik; Uppsala universitet/Institutionen för cell- och molekylärbiologi; Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Krishna Narayan; [2017]
    Keywords : Microtechnology; Biotechnology; Nanotechnology;

    Abstract : In this project, fabrication and characterization of nano/microfluidic channels on borosilicate glass substrate were carried out using a Photo/Ultraviolet (UV) lithography method, which has applications in single-cell analysis. In our single-cell analysis glass system, the bacterial cells will be made to sit in the micrometer channels and also the sub-micron size channels around 300 nm is aspired so it helps in passing the fluid to the outlet hole while holding the cells back.
