The importance of nanotechnology in medical technologies, especially biomedical diagnostics, is indubitable. By taking advantages of nanomaterials, many medical diagnostics methods have been developed so far, including electrochemical nanobiosensors. They have been used for quantification of different clinical biomarkers for detecting, screening, or follow up a disease. microRNAs (miRNAs) are o...

DNA nanotechnology holds the potential for enabling new tools for biomedical engineering, including diagnosis, prognosis, and therapeutics. However, applications for DNA devices are thought to be limited by rapid enzymatic degradation in serum and blood. Here, we demonstrate that a key aspect of DNA nanotechnology-programmable molecular shape-plays a substantial role in device lifetimes. These ...

In recent years nanotechnology has become part of the content of many undergraduate chemistry and physics degree courses. This paper deals with the role of contextualisation of nanotechnology in the delivery of the content, as nanotechnology is only now being slowly integrated into many chemistry degree courses in Ireland and elsewhere. An evaluative methodology of the pedagogical approach for ...

Nanotechnology has become more and more potentially used in diagnosis or treatment of diseases. Advances in nanotechnology have led to new and improved nanomaterials in biomedical applications. Common nanomaterials applicable in biomedical applications include liposomes, polymeric micelles, graphene, carbon nanotubes, quantum dots, ferroferric oxide nanoparticles, gold nanoparticles (Au NPs), a...

objective(s): this paper describes coating of magnetite nanoparticles (mnps) with amorphous silica shells.   materials and methods: first, magnetite (fe3o4) nps were synthesized by co-precipitation method and then treated with stabilizer molecule of trisodium citrate to enhance their dispersibility. afterwards, coating with silica was carried out via a sol-gel approach in which the electrostati...

recent progress in nanotechnology and electrochemical methods can be applied to fine control of the size, crystal structure, and surface properties of iron oxide nanoparticles. here we appliedcathodic electrochemical deposition (ced) as an efficient and effective tactic for synthesisand double coating of surface of superparamagnetic iron oxide nanoparticles (spions). in first step, bare fe3o4 n...

Titanium dioxide (TiO2) is one of the most abundantly used nanomaterials for human life. It is used in sunscreen, photovoltaic devices, biomedical applications and as a food additive and environmental scavenger. Nano-TiO2 in biomedical applications is well documented. It is used in endoprosthetic implants and early theranostics of neoplastic and non-neoplastic maladies as a photodynamic therape...

Cold atmospheric plasma (CAP) is an ionized gas where the ion temperature is close to room temperature as opposed to typical high-temperature laboratory plasmas. It can be carried out in the presence of Helium (He) with a high voltage. CAP is composed of various electrons, positive/negative ions, reactive oxygen species (ROS), reactive nitrogen species (RNS), radicals, excited molecules, energe...
