Nanoparticles in Biomedicine-Focus on Imaging Applications

Abstract

Over the last two decades, nanotechnology has become one of the most dynamically evolving field of research. Various types of nanoparticles are widely exploited to extend our understanding of biological interactions at the molecular level. They are actively engaged in the biomedical research for imaging, biosensing, drug delivery and/or concurrent therapy. Recent progress on this field is briefly reviewed here with an emphasis placed on the wide imaging applications of nanoparticles. Collectively, this field will no doubt make greater impact after we gradually address any potential risks of nanoparticles.

Biocompatible, Multi-Mode, Fluorescent, T2 MRI Contrast Magnetoelectric-Silica Nanoparticles (MagSiNs), for On-Demand Doxorubicin Delivery to Metastatic Cancer Cells

“…For suitability as a drug carrier, it was important to assess the cytocompatibility and biocompatibility of MagSiNs [ 51 ]. Cytocompatibility was assessed against HUVEC cells, which is model cell line for blood vessels and is utilized extensively to assess the cytocompatibility of intravenously delivered therapeutics.…”

Application of Multivariate and Spectroscopic Techniques for Investigation of the Interactions between Polyelectrolyte Layers in Layer‐by‐Layer Assembled pH‐Sensitive Nanocapsules

“…Nano‐sized capsules and nanoparticles with better performance in pharmaceuticals have significantly attracted the attention of many researchers and are used in many fields such as imaging applications, photo catalysis, photovoltaic performance, and catalytic degradation of pollutants. [ 8–15 ] For example, Morey et al. figured out that increasing the contact area between drugs and flawless nanoparticles resulted in better detoxification of drugs compared with micro‐sized particles.…”

Crystallization investigation of BaTiO 3 coating layer on Ni nanoparticles

“…Many efforts have been paid to solve these problems, among which coating the Ni nanoparticles with crystalline oxide layers has been proved to be the most effective method [12][13][14][15][16]. However, due to the surface curvature and the reaction condition, the crystallization of the oxide coating layers is quite difficult [17][18][19][20].…”
