SERS Probing of Proteins in Gold Nanoparticle Agglomerates

Autor: Gergo Peter Szekeres, Janina Kneipp

Publikováno v: Frontiers in Chemistry, Vol 7 (2019)

The collection of surface-enhanced Raman scattering (SERS) spectra of proteins and other biomolecules in complex biological samples such as animal cells has been achieved with gold nanoparticles that are introduced to the sample. As a model for such

Analytical challenges of glycosaminoglycans at biological interfaces

Autor: Gergo Peter Szekeres, Kevin Pagel, Zsuzsanna Heiner

Publikováno v: Analytical and Bioanalytical Chemistry

The analysis of glycosaminoglycans (GAGs) is a challenging task due to their high structural heterogeneity, which results in diverse GAG chains with similar chemical properties. Simultaneously, it is of high importance to understand their role and be
