Compléter EncapsulacionVersion en ligne Descripción para la síntesis de nano esferas par Noé Sánchez 1 nanomaterials electrospinning electrospinning coaxial engineering concentric spinnerets coaxial encapsulation In the last decade , the fraternity witnessed the introduction of modified electrospinning in the form of , involving an arrangement of multiple meant to co - spin compound nano - and micro - scale fibers . These have since acted as precursors for a number of sophisticated applications , such as fabrication of hollow and porous structures , and of biological agents for transport to desired parts of the body . This chapter explores the principles and mechanisms of both the practical and theoretical approaches during , including the latest technologies and the parameters crucial for the quality and quantities yielded .
