We highlight several nanostructures schemes to combat virus-related diseases.

Protein engineering approach enables effective immobilisation of thermostable affinity proteins onto polystyrene materials.

Development and comparison of the first electrochemical bioplatforms for determining anti-centromere B antibodies (CENPB-Abs) developed in magnetic microbead-assisted or integrated formats using His-tag chemistry.

A point-of-care/use lateral flow assay (LFA) is reported for the detection of P. gingivalis endotoxin, a major saliva biomarker for oral health.

Ion transfer voltammetry of de-ionised perfluorooctanoic acid (PFOA) was employed to achieve nanomolar detection and to assess sample matric effects.

We developed an interfacial elasto-inertial microfluidic device for the high-throughput and high-purity separation of malignant tumor cells (MTCs) from pleural and peritoneal effusions.

A copolymer-modified glass nanopore combined with microdialysis was used for assaying cerebral Aβ monomer and Zn²⁺. In the presence of Aβ monomer, the copolymer stretched. Then, the Zn²⁺ altered surface charges and fluorescence.

A microfluidic assay integrated with capillary network-inspired microcapillary arrays and endothelial-associated protein functionalization enables concurrent assessment of red blood cell adhesion and microcapillary occlusion.

A fast approach for synthesizing gold nanoparticles over electrochemical paper-based devices is reported. The device was fabricated by paper laser pyrolysis carbonization followed by in situ laser synthesis of AuNPs.

An array-based artificial tongue consisting of C-dots, TMPyP (porphyrin derivative) and a C-dot–TMPyP complex for the discrimination of different metal ions.

We proposed a novel strategy for analyzing aptamer dominated sites and a AFB1 biosensor was developed based on the results.
