Glycoprofiling of cancer biomarkers: Label-free electrochemical lectin-based biosensors
(
De Gruyter
, 2015 , Article)
Glycosylation of biomolecules is one of the most prevalent post- and co-translational modification in a human body, with more than half of all human proteins being glycosylated. Malignant transformation of cells influences ...
Graphene as a signal amplifier for preparation of ultrasensitive electrochemical biosensors
(
Springer-Verlag
, 2015 , Article)
Early diagnostics of diseases performed with minimal money and time consumption has become achievable due to recent advances in development of biosensors. These devices use biorecognition elements for selective interaction ...

(
Nature Publishing Group
, 2015 , Article)
HKU1 is a human betacoronavirus that causes mild yet prevalent
respiratory disease1, and is related to the zoonotic SARS2 and
MERS3 betacoronaviruses, which have high fatality rates and
pandemic potential. Cell tropism ...
Tryptophan-functionalized gold nanoparticles for deep UV imaging of microbial cells
(
Elsevier
, 2015 , Article)
Biocompatible fluorescent nanostructures were prepared by a functionalization of gold nanoparticles with the amino acid tryptophan. The gold-tryptophan bioconjugates were investigated by TEM and HRTEM and various spectroscopy ...
