“…The magnetic coercivity usually exhibits a maximum at a given particle size above which the internal magnetic structure of the material shifts from single-to multiple-domain [27,28]. The particle size for which we observed maximum coercivity (50 nm) is in good agreement with previously reported values associated with this change in the domain structure, which typically range from 30 to 80 nm for magnetite [27][28][29][30].…”

Healing of micro-cracks is crucial for recovering the mechanical properties and extending the service time of bituminous materials. However, crack closure is often challenged by the efficiency and repeatability of the healing process or its technical and economic feasibility for large-scale applications. Here, we propose an innovative method to close micro-cracks in bituminous materials by using magnetically-triggered iron oxide nanoparticles as heating agents. Heating is generated through the so-called hyperthermia effect upon exposure of the nanoparticles to an external oscillating magnetic field. When mixed in a low volume fraction of 1 % within bitumen, the nanoparticles generate enough heat to decrease the viscosity of the

“…The biocompatible polymeric nanoparticles help to overcome problems related to stability, cytotoxicity, biocompatibility, biodegradability, etc. They improve the efficacy of drugs and reduce side effects via direct targeting and site-specific sustained/controlled delivery with enhanced cellular uptake [ 1 , 2 ]. Inorganic nanoparticles synthesized for biomedical applications can be embedded in biocompatible polymers to reduce the toxicity and enhance cellular acceptance.…”

Biodegradable polymers are popularly being used in an increasing number of fields in the past few decades. The popularity and favorability of these materials are due to their remarkable properties, enabling a wide range of applications and market requirements to be met. Polymer biodegradable systems are a promising arena of research for targeted and site-specific controlled drug delivery, for developing artificial limbs, 3D porous scaffolds for cellular regeneration or tissue engineering and biosensing applications. Several natural polymers have been identified, blended, functionalized and applied for designing nanoscaffolds and drug carriers as a prerequisite for enumerable bionano technological applications. Apart from these, natural polymers have been well studied and are widely used in material science and industrial fields. The present review explains the prominent features of commonly used natural polymers (polysaccharides and proteins) in various nanomedical applications and reveals the current status of the polymer research in bionanotechnology and science sectors.
