3D Super-resolution Label-free Imaging

Conference on Lasers and Electro-Optics, 2016
We present 3D images of grooves on a writable Blu-rayr disc. In the vertical direction the resolution is a few nanometers while the lateral resolution is a few tenths of nanometers.

Photoluminescent polymer nanoparticles for label-free cellular imaging

Chemical Communications, 2010
Novel polymer based photoluminescent nanoparticles were fabricated by ultra-sound induced emulsion polymerization and applied to bioimaging of human breast cancer SK-BR-3 cells after ethylenediamine treatment and conjugation with anti-ErbB2 antibody.

Label-Free in Situ SERS Imaging of Biofilms

The Journal of Physical Chemistry B, 2010
Surface-enhanced Raman scattering (SERS) is a promising technique for the chemical characterization of biological systems. It yields highly informative spectra, can be applied directly in aqueous environment, and has high sensitivity in comparison with normal Raman spectroscopy.

Imaging label-free intracellular structures by localisation microscopy

Micron, 2011
Localisation microscopy methods allow to realize a light optical resolution far beyond the Abbe-Rayleigh limit of about 200 nm laterally and 600 nm axially. So far, this progress was achieved using labelling with appropriate fluorochromes and fluorescent proteins.

Label-free quantitative imaging of conjunctival goblet cells

The Ocular Surface
To introduce and validate quantitative oblique back-illumination microscopy (qOBM) as a label-free, high-contrast imaging technique for visualizing conjunctival goblet cells (GCs) and assessing their functional changes.qOBM was developed in conjunction with moxifloxacin-based fluorescence microscopy (MBFM), which was used for validating GC imaging ...

Terahertz imaging for label-free protein detection

2009 34th International Conference on Infrared, Millimeter, and Terahertz Waves, 2009
We demonstrate an imaging method combined a terahertz time-domain spectroscopy and an interference effect for label-free protein detection on a membrane filter. Biotin is linked to the membrane using poly ethylene glycol (PEG) or poly ethylene glycol methyl ether (MPEG) to prevent it from being washed off.
