Advances in Biosensors Technology for Detection and Characterization of Extracellular Vesicles

Sensors, 2021
Exosomes are extracellular vehicles (EVs) that encapsulate genomic and proteomic material from the cell of origin that can be used as biomarkers for non-invasive disease diagnostics in point of care settings.

Flat fiber: the flexible format for distributed lab-on-a-chip [PDF]

, 2007
Integrated optical devices offer dense, multifunctional capability in a single robust package but are rarely considered compatible with the fields of remote or distributed sensing or long-haul 'one-dimensional' fibers.

Online monitoring of biofouling using coaxial stub resonator technique

Sensing and Bio-Sensing Research, 2015
Here we demonstrate the proof-of-principle that a coaxial stub resonator can be used to detect early stages of biofilm formation. After promising field tests using a stub resonator with a stainless steel inner conductor as sensitive element, the ...

Lab-on-a-Chip method uncertanties in determination of high-molecular-weight glutenin subunits [PDF]

Chemical Industry and Chemical Engineering Quarterly, 2013
Polymeric wheat endosperm proteins, especially the high-molecular-weight glutenin subunits (HMW-GS), are probably the most interesting protein fraction giving the essential information about bread-making quality of wheat flour.

Lab-on-a-Chip: Frontier Science in the Classroom [PDF]

Journal of Chemical Education, 2017
Lab-on-a-chip technology is brought into the classroom through development of a lesson series with hands-on practicals. Students can discover the principles of microfluidics with different practicals covering laminar flow, micromixing, and droplet generation, as well as trapping and counting beads.

Ruthenium Oxide pH Sensing for Organs-On-Chip Studies

Proceedings, 2018
A ruthenium oxide (RuOx) electrode is being developed as potentiometric pH sensor for organs-on-chip applications. Open-circuit potential (OCP) of the RuOx electrode showed a response of −58.05 mV/pH, with no cross-sensitivity to potentially ...
