Researchers review materials used to design biosensors for SARS-CoV-2 detection The SARS-CoV-2 virus is still causing a dramatic loss of human lives worldwide, constituting an unprecedented challenge for society, public health, and economy, to overcome. Currently, SARS-CoV-2 can be diagnosed in two different ways: i) antigen tests (point-of-care, POC) and ii) molecular tests (nucleic acid, RNA, or PCR-polymerase chain reaction). Antigen tests can detect parts of SARS-CoV-2 proteins, known as antigens, via a nasopharyngeal or nasal swab sampling method. The main advantages of POC-test include the high specificity, quick response (less than an hour), and portability, with no need of fixed laboratory facilities. ....
In precision imaging of various biochemical phenomena, gold-coated surfaces play a role that is growing with importance. There are many unique qualities that make gold surfaces perfect for atomic-scale observations, including useful adsorption properties with bioactive implications and near-total (>99%) reflectivity in the infrared (IR) region. In numerous types of IR spectroscopy, this has proven pivotal, where gold-coated glass is employed as a substrate for biomolecules of interest. Mica and glass are not the only substrates utilized for microscopy-grade gold thin films. Platypus Technologies engineer gold-coated silicon wafers which exploit the unique electrical conductivity of both the coating and the substrate to allow advanced electrochemical experimentation ....

In Vivo Probes for Detecting Inflammation Markers in Humans and Animals Thought LeadersProf. Parastoo HashemiSenior Lecturer in Bioengineering, Imperial London College Associate Professor of Chemistry, University of South Carolina In this interview, News-Medical Life Sciences talks to Parry Hashemi about the research on in vivo probes for detecting inflammation markers in humans and animals that she will present at Pittcon. What are some traditional methods for detecting inflammation markers in humans and animals? Traditionally, a blood or plasma sample will be taken. There are certain proteins that indicate an inflammation; for example, pro-inflammatory cytokines. If the levels of these are raised that corresponds to inflammation. ....
