“…Biosensors are analytical devices applied for the detection of biological and chemical samples (Pourakbari et al 2019). A biosensor can be defined as a probe that integrates a biological analyte recognition system with an electronic transducer; thus, converting a biochemical signal into a measurable electrical or optical signal (Mobed et al 2019).…”

“…A biosensor can be defined as a probe that integrates a biological analyte recognition system with an electronic transducer; thus, converting a biochemical signal into a measurable electrical or optical signal (Mobed et al 2019). The structure of biosensors usually consists of a bioreceptor or biological recognition component, a signal transducer, and an amplifier (Mobed et al 2019;Pourakbari et al 2019). The interaction between the analyte and the bioreceptor is transformed into quantifiable signals.…”

“…Electrochemical biosensors are highly valued by biomedical and environmental research due to their simplicity and sensitivity. The main electrochemical methods involved in biosensor designing include voltammetry/amperometry, potentiometry, impedance, and conductometry (Mobed et al 2019;Pourakbari et al 2019). Highly conductive nanomaterials are widely used in biosensor constructions, whether organic carbon or inorganic metal nanoparticles.…”

Mycobacteria in drinking water and in the water of swimming pools, whirlpools, hydrotherapy facilities and aquaria contribute significantly to human exposure to triggers of immune regulated chronic inflammatory and autoimmune diseases. Technological elements of water distribution systems, especially their inner surface, taps, shower heads and blind spots where sediments settle, affect the number of mycobacteria in the water. The review presents the possibilities of using analytical instruments for rapid determination of mycobacteria and for their typing as an alternative to classical culture and a method of monitoring specific nucleic acid sequences by polymerase chain reaction (PCR). Information about the use of flow cytometry (FCM), matrix-assisted laser desorption ionisation time-of-flight (MALDI-TOF) spectrometry, Raman and infrared (IR) spectroscopy and biosensors are presented.

In nowadays, we have entered the new era of pandemics and the significance of virus detection deeply impacts human society. Viruses with genetic mutations are reported nearly every year, and people have prepared tools to detect the virus and vaccines to ensure proper treatments. Influenza virus (IV) is one of the most harmful viruses reporting various mutations, sub-types, and rapid infection speed for humans and animals including swine and poultry. Moreover, IV infection presents several harmful symptoms including cough, fever, diarrhea, chills, even causing death. To reduce the IV-induced harm, its proper and rapid detection is highly required. Conventional techniques were used against various IV sub-types including H1N1, H3N2, and H5N1. However, some of the techniques are time-consuming, expensive, or labor-intensive for detecting IV. Recently, the nucleic acid-based aptamer has gained attention as a novel bioprobe for constructing a biosensor. In this review, the authors discuss the recent progress in aptasensors for detecting IV in terms of an electrochemical and an optical biosensor.

“…Higher resolutions and sensitivities can now be achieved. The inclusion of nanomaterials such as nanostructured surfaces or nanoparticles has generated a great deal of interest in the biosensing community [113][114][115]. The addition of new physical and chemical properties, as well as the increase of the specific surface area, opens up now possibilities.…”

Antimicrobial Peptides as Probes in Biosensors Detecting Whole Bacteria: A Review

Bacterial resistance is becoming a global issue due to its rapid growth. Potential new drugs as antimicrobial peptides (AMPs) are considered for several decades as promising candidates to circumvent this threat. Nonetheless, AMPs have also been used more recently in other settings such as molecular probes grafted on biosensors able to detect whole bacteria. Rapid, reliable and cost-efficient diagnostic tools for bacterial infection could prevent the spread of the pathogen from the earliest stages. Biosensors based on AMPs would enable easy monitoring of potentially infected samples, thanks to their powerful versatility and integrability in pre-existent settings. AMPs, which show a broad spectrum of interactions with bacterial membranes, can be tailored in order to design ubiquitous biosensors easily adaptable to clinical settings. This review aims to focus on the state of the art of AMPs used as the recognition elements of whole bacteria in label-free biosensors with a particular focus on the characteristics obtained in terms of threshold, volume of sample analysable and medium, in order to assess their workability in real-world applications.
