“…While the rod-like Au NPs were grown on the paper working zone, the peak current (curve b) was increased compared to bare paper based m-PADs. After the modification of the CP and blocked, the peak current (curve c) became lower than that of the previous stage, which may be owing to the particularity of the DNA backbone by carrying negative charges and the rejection effect of MCH on the contact between [Fe(CN) 6 ] 3À/4À and the m-PADs. As expected, the peak current decreased sequentially (curves d, e) after binding with the IS and the following HCR, which may be caused by the more negative charges import to the modified working zone as well as the formation of the DNA polymers.…”

In this paper, a microfluidic paper-based analytical device is presented for sensitively detecting peptides based on the specific recognition of aptamer and the amplification strategy of hybridization chain reaction (HCR). The aptamer/initiation strand (AP/IS) was designed for the specific target recognition, and the presence of the target peptide could release the initiating sequence from the AP/IS. The released IS could trigger the HCR between two hairpin probes, which could complete the detection for the targets indirectly when the electrochemiluminescence (ECL) probe (Ru(phen) 3 2 + ) is introduced into the double-strand DNA grooves,which could produce a significantly amplified ECL signal output. Mucin-1 was employed as a model peptide, and the detection limit of the proposed assay is calculated as 8.33 pMwith a range from 25 pM to 50 nM. The novel sensing platform can be widened for the detection of other kinds of peptides as well as potentials used for sensitively detecting other biomolecules, and even cells.

“…The limit of detection for Salmonella in pasteurized milk was 23 cfu/mL and thus similarly low as the one the group got for the E. coli analysis [69]. In 2007, the group of Keusgen also tried to assemble a suitable SPRbased sensor for the rapid detection of antiseptically killed Salmonella typhimurium in milk [75]. They used a sandwich detection format with a polyclonal capture antibody that was immobilized by self-assembly on a hydrophobic sensing surface formed by alkylsilanes and the same antibody as auxiliary detection agent.…”

Optical sensors based on the excitation of surface plasmons, referred to as surface plasmon resonance (SPR) sensors, have become a central analytical tool for characterizing and quantifying a wide variety of macromolecular interactions, like receptor-ligand contacts. Besides this classical field of application, in the last 15 years, the development of SPR sensors aiming for the detection and analysis of ligand/cell or host/pathogen interactions, cell/ cell contacts, and cellular reactions gained considerable momentum. The number of publications reporting about applications of SPR sensors implementing vital prokaryotic or eukaryotic cells as biorecognition elements for medical diagnostics, environmental monitoring, or biological safety is steadily growing. This review gives a short introduction to the technique of surface plasmon resonance and the parameters that are important for its application in the field of vital cell sensors. Furthermore, the publications concerning the application of such sensors in the analysis of cellular interactions and cellular reactions to extra-and intracellular stimuli are summarized.

“…can survive outside of their natural habitat, e.g., in water and food products (White et al, 2002). Salmonella detection by SPR-based assays with antibodies as the recognition element has been described in many studies (Bokken et al, 2003;Oh et al, 2004;Mazumdar et al, 2007;Dudak and Boyaci, 2009;Mazumdar et al, 2010;Singh et al, 2015;Vaisocherová-Lísalová et al, 2016).…”

Background: Foodborne pathogens are a growing concern with respect to human illnesses and death. There is an increasing demand for improvements in global food safety. However, it is a challenge to detect and identify these harmful organisms in a rapid, responsive, suitable, and effective way. Results: Rapid developments in biosensor designs have contributed to the detection of foodborne pathogens and other microorganisms. Biosensors can automate this process and have the potential to enable fast analyses that are cost and time-effective. Various biosensor techniques are available that can identify foodborne pathogens and other health hazards. Conclusions: In this review, biosensor technology is briefly discussed, followed by a summary of foodborne pathogen detection using various transduction systems that exhibit specificity for particular foodborne pathogens. In addition, the recent application of biosensor technology to detect pesticides and heavy metals is briefly addressed.
