Carrier Systems

Different nanocarrier systems owing to their nano size, increased surface area and unique electrical and magnetic properties are employed for biomedical applications. Among the various nanocarrier systems, hollow nanocapsules are one of the most interesting carrier systems for thier use in bioimaging and biomedical applications. The unique properties of hollow nanocapsules make them suitable for use in bioimaging. In this article hollow nanocpsules have been classified into four classes based on thier composition: (i) liposomes, (ii) polmersomes and other polymeric hollow nanocapsules, (iii) metallic hollow nanocapsules and (iv) others. The formation and design of these hollow nanocapsules and their diagnostic and therapeutic applications using different agents/imaging probes and imaging modalities is discussed briefly. Hollow nanocapsules have revolutionized the field of biomedical imaging.

Abstract The evolution of neurosurgery has been, and continues to be, closely associated with innovations in technology. Modern neurosurgery is wed to imaging technology and the future promises even more dependence on anatomic and, perhaps more importantly, functional imaging. The photoacoustic phenomenon was described nearly 140 yr ago; however, biomedical applications for this technology have only recently received significant attention. Light-based photoacoustic and microwave-based thermoacoustic technologies represent novel biomedical imaging modalities with broad application potential within and beyond neurosurgery. These technologies offer excellent imaging resolution while generally considered safer, more portable, versatile, and convenient than current imaging technologies. In this review, we summarize the current state of knowledge regarding photoacoustic and thermoacoustic imaging and their potential impact on the field of neurosurgery.

Electrical And Magnetic Properties

Amorphous materials are of current interest due to their desirable mechanical, electrical and magnetic properties. Furthermore, crystallizing amorphous alloys provides an avenue for discerning sequential and competitive phases thus allowing access to otherwise inaccessible crystalline structures. Previous studies have shown the benefits of using AEM to determine crystal structures and compositions of partially crystallized alloys. The present paper will discuss the AEM characterization of crystallized Cu-Ti and Ni-Ti amorphous films.Cu60Ti40: The amorphous alloy Cu60Ti40, when continuously heated, forms a simple intermediate, macrocrystalline phase which then transforms to the ordered, equilibrium Cu3Ti2 phase. However, contrary to what one would expect from kinetic considerations, isothermal annealing below the isochronal crystallization temperature results in direct nucleation and growth of Cu3Ti2 from the amorphous matrix.
