“…[16] The properties of metal oxides can be tailored through various techniques such as controlling morphology, calcination, surface modification, doping, etc. [19,20] Considerable enhancement in the structural, electrical, and electronic properties of SnO 2 has already been reported by being doped with appropriate materials. [21] Doping with transition metal is found to have a deep influence on the properties of the tin oxide.…”

Tin oxide (SnO2) and iron-doped tin oxide (Sn1 – x Fe x O2, x = 0.05 wt%, 0.10 wt%) nanoparticles are synthesized by the simple sol–gel method. The structural characterization using x-ray diffraction (XRD) confirms tetragonal rutile phases of the nanoparticles. The variations in lattice parameters and relative intensity with Fe-doping concentration validate the incorporation of iron into the lattice. The compressive strain present in the lattice estimated by using peak profile analysis through using Williamson–Hall plot also exhibits the influence of grain boundary formation in the lattice. The radiative recombination and quenching observed in optical characterization by using photoluminescence spectrum (PL) and the shift in the band gap estimated from UV-visible diffused reflectance spectrum corroborate the grain boundary influence. Raman spectrum and the morphological analysis by using a field emission scanning electron microscope (FESEM) also indicate the formation of grain boundaries. The compositional analysis by using energy dispersive x-ray spectrum (EDAX) confirms Fe in the SnO2 lattice. The conductivity studies exhibit that the impendence increases with doping concentration increasing and the loss factor decreases at high frequencies with doping concentration increasing, which makes the Sn1 – x Fe x O2 a potential candidate for device applications.

Solid colloidal particles of size from 10 to 1000 Nanometre are known as Nanoparticles. Nanoparticles contribute many benefits to bigger particles such as enhanced surface-to-volume ratio and enhanced magnetic properties. Over the last few years, there has been an undeviating growing interest in using nanoparticles in different biomedical applications such as targeted drug delivery, hyperthermia, photo ablation therapy, bio imaging, and biosensors. Iron oxide nanoparticles have dominated applications, such as drug delivery, hyperthermia, bio imaging, cell labelling, and gene delivery, because of their superior properties such as chemical stability, non-toxicity, biocompatibility, high saturation magnetization, and high magnetic susceptibility. In this paper, biomedical applications of two different types of nanoparticles metal oxide nanoparticles and carbon nanotubes are discussed.
