“…The SPR response is directional and sensitive to the interactions between biomolecules, as well as to nonspeci ic protein adsorption. To evaluate the antifouling ability of the peptide-based aptasensor, 1 mg / ml HSA, 1 mg/ml BSA and 2 μg/ml Lys single-protein solutions were used to assay nonspeci ic adsorption because those proteins contain hydrophobic, hydrophilic, and charged regions and can adhere to surfaces by hydrogen-bonding, electrostatic, charge-transfer, and/or hydrophobic interactions [38]. In addition, the proteins are normally in serum, and their concentrations are much higher than cTnI.…”

“…Especially research laboratories may benefit from 3D printing as a flexible small-manufacturing tool not limited to flow cells or open cells. Instead, it opens access to a range of useful laboratory tools, while no special training is needed for the manufacturing process [40][41][42][43][44][45]. In brief, based on CAD (computer-aided design) modelling, a 3D model is structured into a finite number of layers to be printed layer by layer.…”

Electrochemical spectroscopy enables rapid, sensitive, and label-free analyte detection without the need of extensive and laborious labeling procedures and sample preparation. In addition, with the emergence of commercially available screen-printed electrodes (SPEs), a valuable, disposable alternative to costly bulk electrodes for electrochemical (bio-)sensor applications was established in recent years. However, applications with bare SPEs are limited and many applications demand additional/supporting structures or flow cells. Here, high-resolution 3D printing technology presents an ideal tool for the rapid and flexible fabrication of tailor-made, experiment-specific systems. In this work, flow cells for SPE-based electrochemical (bio-)sensor applications were designed and 3D printed. The successful implementation was demonstrated in an aptamer-based impedimetric biosensor approach for the detection of Escherichia coli (E. coli) Crooks strain as a proof of concept. Moreover, further developments towards a 3D-printed microfluidic flow cell with an integrated micromixer also illustrate the great potential of high-resolution 3D printing technology to enable homogeneous mixing of reagents or sample solutions in (bio-)sensor applications.

“…SPR is a sensitive, specific, label-free technique that can measure binding affinities in real time on the basis of kinetic constants and thermodynamic parameters ( Kumbhat et al, 2010 ). Furthermore, this method has successfully identified the kinetics of biological molecules, including protein binding, antibody–ligand binding, various foods, lipid raft formation and drugs ( Fu et al, 2019 , Zhang et al, 2019 , Visentin et al, 2018 , Bahri et al, 2019 , Ryu et al, 2019 , Mowla et al, 2018 ).…”

Dengue is an acute febrile disease caused by dengue virus (DENV) that is transmitted by Aedes sp., which causes serious health conditions in many countries. Non-structural protein 1 (NS1) is a co-factor for the RNA replication of this virus, which represents a new strategy for the identification of dengue. Prompt and accurate laboratory diagnosis of this infection is required to assist in patient triage and management, as well as prevent the spread of this infection. In the present study, we tested the potential of surface plasmon resonance (SPR) as a diagnostic tool for dengue infections. NS1 antigen protein was used as an analyte that targets anti-NS1 antibodies, with their interaction resulting in a change in the refractive index. In comparison to currently available gold-standard detection methods [enzyme-linked immunosorbent assay (ELISA) and reverse transcription polymerase chain reaction (RT-PCR)], SPR showed a similar sensitivity but greater efficiency and simplicity in terms of infection detection. Out of 26 samples collected from patients with dengue in Indonesia, SPR was able to correctly identify all 16 positively infected individuals at a lower concentration and a shorter period of time compared to ELISA and RT-PCR. This study revealed that SPR is a promising tool for DENV detection and potentially other diseases as well.
