We investigated a prototype of strain sensor based on the layers bionanomaterial containing bovine serum albumin (BSA matrix) and multi-walled carbon nanotubes (MWCNT filler). The aqueous dispersion 25 wt.% BSA/0.3 MWCNT was applied by screen printing onto flexible polyethylene terephthalate substrates. After drying laser irradiation (~970 nm), various parameters were controlled, i.e., resistan...

Aptamers are single-strand DNA or RNA selected in vitro that bind specifically with a broad range of targets from metal ions, organic molecules, to proteins, cells and microorganisms. As an emerging class of recognition elements, aptamers offer remarkable convenience in the design and modification of their structures, which has motivated them to generate a great variety of aptamer sensors (apta...

Electrochemical aptasensors, which are based on the specificity of aptamer-target recognition, with electrochemical transduction for analytical purposes have received particular attention due to their high sensitivity and selectivity, simple instrumentation, as well as low production cost. Aptamers are functional nucleic acids with specific and high affinity to their targets, similar to antibod...

As more engineered nanomaterials (eNM) are developed for a wide range of applications, it is crucial to minimize any unintended environmental impacts resulting from the application of eNM. To realize this vision, industry and policymakers must base risk management decisions on sound scientific information about the environmental fate of eNM, their availability to receptor organisms (eg, uptake)...

Blood glucose monitoring is considered the gold standard for diabetes diagnostics and self-monitoring. However, the underlying process is invasive and highly uncomfortable for patients. Furthermore, the process must be completed several times a day to successfully manage the disease, which greatly contributes to the massive need for non-invasive monitoring options. Human serums, such as saliva,...

The new revolution in dental materials is due to use of nanomaterials in dentistry. Graphene is one of the carbon nanoallotrope that has the potential to enhance properties of materials used in dentistry. The use of this 2D crystal is dentistry is virtue to its typical properties that provides improved performance, extended functionality in materials. In this paper, a review is done to study 3D...

Self-assembled particles of genetically engineered human L subunit ferritin expressing a silver-binding peptide were used as nanocontainers for the synthesis of silver nanoparticles. The inner cavity of the self-assembled protein cage displays a dodecapeptide that is capable of reducing silver ions to metallic silver. This chimeric protein cage when incubated in the presence of silver nitrate e...
