Biotech Companies Invest Microfluidic Device Development for Pathogen Detection

 Emerging COVID-19 variants have encouraged many biotech giants to actively participate in developing microfluidic devices for rapid and accurate SARS-CoV-2 detection.

 

Though the current global wave of the omicron COVID-19 variant is relatively mild in terms of causing severe disease and death, it's necessary to continuously develop new technologies and strategies to identify and resist COVID-19 infection in case more aggressive variants may come around from nowhere. Microfluidics, a highly miniaturized, automatic, and integrated technology, is expected to perform rapid, low-cost, accurate, and point-of-care detection of infectious diseases like COVID-19. Researchers from leading life science companies like Creative Biolabs have gotten involved in developing and designing microfluidic devices for different applications, including devices for quick and accurate SARS-CoV-2 detection.

 

Microfluidic Chips for Pathogen Detection

 

Infectious diseases arise from pathogens, including bacteria, viruses, and parasites, with global distribution and transmission between individuals. Scientists have developed some disposable microfluidic chips that can detect pathogens simply with drops of biological fluids, such as saliva, blood, sweat, and urine. For instance, a microfluidic chip can accurately detect the SARS-CoV-2 virus with a few drops of saliva with fluorescent antibodies against the virus, whose accuracy could be comparable to the gold-standard test, PCR.

 

Besides the SARS-CoV-2 virus, the microfluidic chips are versatile in manipulating and detecting many other pathogens, including seasonal coronavirus, HIV, influenza viruses, the Zika virus, H1N1 influenza virus, and even microorganisms like Legionella and E. coli. Moreover, microfluidic chips have also been combined with traditional methods like PCR, RT-PCR, qPCR, RT-LAMP due to simplicity in function and fabrication, rapid turnaround time, decreased reagent consumption, reduced contamination, etc.

 

Driven by the rapid advancements of technology, digital microfluidic devices for molecular diagnostics have become attractive and promising tools to deal with the severe COVID-19 pandemic as well as diseases caused by other pathogens.

 

The increasing need of adopting cutting-edge microfluidic-based tools has encouraged life science companies like Creative Biolabs to be dedicated to providing one-stop solutions to microfluidic chip development and design, especially microfluidic chips for tumor marker detection, viruses detection, and fungal infections. Several automatic and portable microfluidic platforms have been established for single-cell analyses, molecular diagnostics, DNA sequencing, PCR amplification, amino acid/peptide/protein analysis, immunoassays, cell sorting, manipulation, and so on.

How Haptens Differ from Antigens and Become Immunogens?

The  difference between antigens vs. haptens  is one the most concerning issues for people who are not familiar with them. As a matter of fact, antigens and haptens are similar in many ways. They are both molecules triggering immune responses and acting as antigenic agents. And they both work as immunogens and bind to antibodies although haptens in a different manner.   What distinguishes an antigen mostly from a hapten is that antigens are complete molecules spontaneously triggering immune response whereas haptens are fragmentary small molecules that are unable to elicit immune responses unless they are conjugated to a larger molecule, known as a carrier.   What are Antigens? Antigen s, including proteins, peptides, and polysaccharides, are immunogen   molecules  that can trigger immune response s or naturally bind to   immune   components . An antigen may have one or more epitopes, which are the determinants of recognition and binding to antibod...

Review: Creative Biolabs' Model-org Antibodies Fluorescently Labeling Services

Model organisms (Model-org) are non-human species, from which researchers can get insights into other organisms in biological research processes. Various model organism species such as zebrafish, flies, yeast, and rice, greatly contribute to the basic and clinical research in animal husbandry, fishery ， agriculture, forestry, etc.   Investigations on model organisms can be aided by antibody labeling when samples of interest need to be detected, isolated, or purified, though the selection of a proper label can be a challenge.   To select the best antibody labeling way for our Model-org project, we then found Creative Biolabs, one of the most well-established CROs for antibody development. After a comprehensive discussion and consultancy with the scientists at Creative Biolabs, fluorescent tags were  suggested based on our research direction. Fluorescent labels are directly conjugated to the antibody of interest, indicating that we can directly detect the number of fluoresc...

Metagenomics Enhances Infectious Disease Surveillance

  Infectious lower respiratory diseases and diarrheal diseases are the leading causes of death globally . And the ongoing COVID-19 pandemic, which has contributed to 4.1 million deaths in 2019, once again is reminding the necessity of proactively identifying early signs of infectious disease outbreaks before things are getting worse. Conventional microbial diagnostics techniques would identify pathogens under specific culture conditions by serological detection of pathogen-associated antibodies or microbial genetic investigation using PCR, but these methods have been seen obvious shortcomings in pathogen coverage. It's highly required to find advanced scientific tools that are more sensitive even with a low microbial load or when targeted microorganisms are not suitable for  in vitro  culture, for which metagenomic approaches that can profile all DNA or RNA of a patient sample are increasingly catching the eyes of researchers.   How metagenomics can be used in infect...
