Nano/Micro Structured Bioglasses Synthesized via Sol-gel and Electrohydrodynamic (EHD) Approaches

摘要

In this paper we shall review our recent research on forming of bioglass architectures using simultaneous flow of precursors through a device which can contain several co-axial needles and operates in an electric field. In particular, research involving sol-gel and electrospinning technique combinations will be described. The co-flow in different situations can be made to jet and produce particles or tubes. In addition, silver ions can be accommodated in the glass precursor so that the Si-O-Si network forming process can be manually interfered at an atomic level, and the bioglass nanotube wall structure can be manipulated, from dense to a 'lace-like' structure (Fig 1a).
