Characterization of community-level substrate utilization via incubation of environmental samples in BIOLOG microplates has been increasingly applied in many areas of microbial ecology. The easily-produced multivariate profile allows for intensive spatial and temporal analysis of microbial communities, and it is a sensitive and reproducible tool for characterizing microbial communities. This wo...

A photonic crystal optical biosensor is incorporated into standard format 96-well microplates for the purpose of detecting the attachment of cells to the biosensor surface without the use of fluorescent labels or any other type of marker. We show that the attachment of cells to the biosensor can be modulated by the immobilization of cognizant ligands to the sensor surface that selectively recog...

In this study the dynamic behaviour of perforated microplates oscillating under the effect of squeeze film damping is analyzed. A numerical approach is adopted to predict the effects of damping and stiffness transferred from the surrounding ambient air to oscillating structures; the effect of hole’s cross section and plate’s extension is observed. Results obtained by F.E.M. models are compared ...

This paper presents a project that is developing a mobile service robot to assist users in biological and pharmaceutical laboratories by executing routine jobs such as filling and transporting microplates. A preliminary overview of the design of the mobile platform with a robotic arm is provided. Moreover, the approaches to localization and intuitive multimodal human-machine interaction using s...

The aim of this article is to analyze nonlinear electro-magneto vibration of a double-piezoelectric composite microplate-system (DPCMPS) pursuant to the nonlocal piezoelasticity theory. The two microplates are assumed to be connected by an enclosing elastic medium, which is simulated by the Pasternak foundation. Both of piezoelectric composite microplates are made of poly-vinylidene fluoride (P...

Equipment and additionally required solutions The -Gal Reporter Gene Assay can be performed in all automated or manual luminometers in tube and microplate format, as well as in scintillation counters. When using the microplate format, black or white microplates must be used. Except for redist. water (required for reconstitution and dilution purposes), the kit contains all assay reagents for lys...

Idoxuridine-treated McCoy cells grown as monolayers in 96 well microplates provide a convenient method for the isolation of Chlamydia trachomatis. Staining of infected monolayers with periodic acid-Schiff reagent (PAS) allows easy recognition of C trachomatis inclusions without the need for dark-ground microscopy. By this method 384 clinical specimens can be examined concurrently. It is suffici...

Introduction Under many experimental conditions autofluorescence of the sample or the microplate can cause unwanted background fluorescence. High background results in variable inter and intraexperimental signals, as well as a decrease in sensitivity. While several options are available to reduce background fluorescence, including the use of low-background microplates and different excitation a...
