Nanoparticles Types, Classification, Characterization, Fabrication Methods and Drug Delivery Applications

Abstract: The most emerging branch in pharmaceutical sciences known as “Pharmaceutical nanotechnology” presents new tools, opportunities and scope, which are expected to have significant applications in disease diagnostics and therapeutics. Recently nano-pharamceuticals reveal enormous potential in drug delivery as carrier for spatial and temporal delivery of bioactive and diagnostics. Additionally it also provides smart materials for tissue engineering. This discipline is now well-established for drug delivery, diagnostics, prognostic and treatment of diseases through its nanoengineered tools. Some nanotech based products and delivery systems are already in market. Pharmaceutical nanotechnology comprised of nano-sized products which can be transformed in numerous ways to improve their characteristics. Drugs that are transformed in to nano range offer some unique features which can lead to prolonged circulation, improved drug localization, enhanced drug efficacy etc. Various pharmaceutical nanotechnology based systems which can be termed as nanopharmaceuticals like polymeric nanoparticles, magnetic nanoparticles, liposomes, carbon nanotubes, quantum dots, dendrimers, metallic nanoparticles, polymeric nanoparticles, etc. have brought about revolutionary changes in drug delivery as well as the total medical service system. With the aid of nanopharmaceuticals, Pharmaceutical nanotechnology could have a profound influence on disease prevention to provide better insights into the molecular basis of disease. However some recently found health risk evidences limits their utilization in pharmaceutical industry. Some concerning issues like safety, bioethical issues, toxicity hazards, physiological and pharmaceutical challenges get to be resolved by the scientists. Current researchers are still lacking sufficient data and guidelines regarding safe use of these nanotechnology based devices and materials. Therefore pharmaceutical nanotechnology is still in infancy. The present chapter summarizes the types of nanopharmaceuticals with the most important applications and nanoparticles associated health risk related information available till present.

A meta-analysis of the impact of technology on learning effectiveness of elementary students

Abstract: The existing studies suggest that if technology is interwoven comprehensively into pedagogy, it can act as a powerful tool for effective learning of the elementary students. This study conducted the meta-analysis by integrating the quantitative findings of 122 peer-reviewed academic papers that measured the impact of technology on learning effectiveness of elementary students. The results confirmed that the technology has a medium effect on learning effectiveness of elementary students. Further, this study analysed the effect sizes of moderating variables such as domain subject, application type, intervention duration, and learning environment. Finally, the impact of technology at different levels of moderating variables has been discussed and the implications for theory and practice are provided.

Natural Polymers vs Synthetic Polymer

Abstract: Polymers play an important role as excipients in any dosage form. They influence drug release and should be stable, economic compatible, non-toxic, etc. They are broadly classified as natural polymers and synthetic polymers. Synthetic and natural based biodegradable polymers have received much more attention in the last decades due their potential applications in the fields related to environmental protection and the maintenance of physical health. Biodegradable materials are used in agriculture, medicine packaging, and other areas. In recent years there has been an increase in interest in biodegradable polymers. Two classes of biodegradable polymers can be distinguished: synthetic or natural polymers. Synthetic polymers are widely used in biomedical implants and devices because they can be fabricated into various shapes. Natural polymers are basically polysaccharides so they are biocompatible and without any side effects. In this chapter we have discussed various natural polymers, their advantages over synthetic polymers and role of natural polymers in designing novel drug delivery systems.
