A fully integrated duplex RT-LAMP device for the detection of viral infections.

Respiratory viruses can cause epidemics or pandemics, which are worldwide outbreaks of disease. The severity of these events varies depending on the virus, its characteristics, along with environmental factors. The frequency of epidemics and pandemics caused by respiratory viruses is difficult to predict, but the potential severity of such events underlines the importance of continued monitoring, research, and preparation for emerging infectious diseases.

Self-Sampled Gargle Water Direct RT-LAMP as a Screening Method for the Detection of SARS-CoV-2 Infections.

We assessed the viability of self-sampled gargle water direct RT-LAMP (LAMP) for detecting SARS-CoV-2 infections by estimating its sensitivity with respect to the gold standard indirect RT-PCR of paired oro-nasopharyngeal swab samples. We also assessed the impact of symptom onset to test time (STT)-i.e.

Detection and identification of using magnetic particle enhanced surface plasmon spectroscopy.

In this work, an approach for SPR spectroscopy using the SPR system is examined that combines signal amplification by PCR and magnetic nanoparticles in one injection step. Therefore, the synthesis of PCR products was performed on the beads similar to a solid-phase PCR, termed PCR-on-a-bead. The functionality of this PCR was proven using an enzymatic assay.

An integrated versatile lab-on-a-chip platform for the isolation and nucleic acid-based detection of pathogens.

Aim: Processing of the samples in molecular diagnostics is complex and labor-intensive. An integrated and automated platform for sample preparation and nucleic acid-based detection can significantly relieve this burden for the users.

Results: We present a prototype of a versatile and integrated platform for the detection of pathogens in various liquid media.

Specific enrichment of prokaryotic DNA using a recombinant DNA-binding protein.

Targeted enrichment of DNA is often necessary for its detection and characterization in complex samples. We describe the development and application of the novel molecular tool for the specific enrichment of prokaryotic DNA. A fused protein comprising the DNA-binding subunit of the bacterial topoisomerase II, gyrase, was expressed, purified, and immobilized on magnetic particles.

Application of nanotechnology in miniaturized systems and its use for advanced analytics and diagnostics - an updated review.

A combination of Micro-Electro-Mechanical Systems and nanoscale structures allows for the creation of novel miniaturized devices, which broaden the boundaries of the diagnostic approaches. Some materials possess unique properties at the nanolevel, which are different from those in bulk materials. In the last few years these properties became a focus of interest for many researchers, as well as methods of production, design and operation of the nanoobjects.
