Automated alignment method for coherence-controlled holographic microscope
Coherence-controlled holographic microscope (CCHM) was developed particularly for quantitative phase imaging and measurement of live cell dynamics, which is the proper subject of digital holographic microscopy (DHM). CCHM ...
Exposure to 17 beta-Oestradiol Induces Oxidative Stress in the Non-Oestrogen Receptor Invertebrate Species Eisenia fetida
Background The environmental impacts of various substances on all levels of organisms are under investigation. Among these substances, endocrine-disrupting compounds (EDCs) present a threat, although the environmental ...
The Composites of Graphene Oxide with Metal or Semimetal Nanoparticles and Their Effect on Pathogenic Microorganisms
The present experiment describes a synthesis process of composites based on graphene oxide, which was tested as a carrier for composites of metal- or metalloid-based nanoparticles (Cu, Zn, Mn, Ag, AgP, Se) and subsequently ...
On-chip three-dimensional cell culture in phaseguides improves hepatocyte functions in vitro
(AIP Publishing, 2015-06-23)
The in vitro study of liver functions and liver cell specific responses to external stimuli deals with the problem to preserve the in vivo functions of primary hepatocytes. In this study, we used the biochip OrganoPlateTM ...
Direct coupling of a free-flow isotachophoresis (FFITP) device with electrospray ionization mass spectrometry (ESI-MS)
(Royal Society of Chemistry, 2015-07-09)
The direct coupling of free-flow isotachophoresis device with an electrospray-ionization-mass-spectrometer allows continuous online detection without any sample preparation such as purification and labeling.
Doubling Throughput of a Real-Time PCR
(Macmillan Publishers, 2015-07-10)
We added an intercallating dye to probe-based real-time PCR. One set of oligonucleotides had FAM probe while the second one was without. We were able to extract two DNA amplification curves using a single fluorescence channel
Nanoliter-sized overheated reactor
(AIP Publishing, 2015-01-16)
We report on a microfluidic system formed by 200 nl water droplets, encapsulated by a 600 nl mineral oil placed on a hydrophobically coated glass microscope cover slip. The micromachined heater underneath the glass was ...
Simultaneous Automatic Electrochemical Detection of Zinc, Cadmium, Copper and Lead Ions in Environmental Samples Using a Thin-Film Mercury Electrode and an Artificial Neural Network
In this study a device for automatic electrochemical analysis was designed. A three electrodes detection system was attached to a positioning device, which enabled us to move the electrode system from one well to another ...
Design and Fabrication of Fully Implantable MEMS Cochlea
The micro-electro-mechanical array for application as fully implantable cochlea is presented in this paper. The complete system including a short overview of energy harvesting and the system configuration is proposed. This ...
Oxidative Stress Resistance in Metastatic Prostate Cancer: Renewal by Self-Eating
Resistant cancer phenotype is a key obstacle in the successful therapy of prostate cancer. The primary aim of our study was to explore resistance mechanisms in the advanced type of prostate cancer cells (PC-3) and to clarify ...
