Helicobacter Pylori (HP) bacteria is considered a very dangerous pathogen with about half the earth population are host. It infects the human gastrointestinal tract causing permanent damages that may lead to cancer. The exact routes of Helicobacter pylori infection transmission is still not fully investigated. Thus, the in-vitro detection of HP is very important in monitoring infections at its early stages and in contaminated mediums like food and water. Literature reports several techniques and approaches to detect HP in-vitro, but mostly with the cost of complex instruments, excessive sample processing and time consuming test methods making them not suitable for affordable routine procedure. This paper contributes in briefly reviewing the few recent detection methods of HP in-vitro. Experience of authors in HP in-vitro detection is presented. The influence of the detection method on sensitivity, selectivity and on compatibility with point-of-care devices is overviewed. Major types of sensors based on antigen-antibody interaction or DNA hybridization are discussed.

“…Hence, using commercially available screen-printing inks for various electrodes is widespread, as these have been optimized for ink stability during the printing process. The most commonly used ink for voltammetric detection are carbon and Ag/AgCl ,,,, for the working, counter, and reference electrodes. Deviations of voltammetric peak areas between electrodes can be below 5% for Pb 2+ and Cd 2+ in the ppb range, making such an approach highly established in voltammetry.…”

This Feature summarizes recent works in paper-based potentiometry and voltammetry in heavy metal determination. Interactions of paper substrates with heavy metals, influence on the sensing response, and modification methods applied to paper substrates to improve the performance of recently developed electrochemical sensors are discussed. Since the rekindling of interest in paper-based analytical devices, methodologies and electrode designs for heavy metal determinations are highlighted. Promising aspects of the use of these sensors for samples containing solids and the increased versatility of the use of paper in analytics offers the possibility of increased acceptance of these low-cost platforms.

“…In addition, the combination of SPE and microfluidic technology can significantly reduce the consumption of reagents and samples. Multiple steps such as sample processing and detection can be integrated through a rational design to achieve a simple, fast and efficient testing [106][107][108][109].…”

Human norovirus (HuNoV) is a food-borne pathogen that causes acute gastroenteritis in people of all ages worldwide. However, no approved vaccines and antiviral drugs are available at present. Therefore, the development of accurate and rapid detection technologies is important in controlling the outbreak of HuNoVs. This paper reviewed the research progress on HuNoV detection, including immunological methods, molecular detection and biosensor technology. Immunological methods and molecular detection technologies are still widely used for HuNoV detection. Furthermore, biosensors will become an emerging developmental direction for the rapid detection of HuNoVs because of their high sensitivity, low cost, easy operation and suitability for onsite detection.
