“…A sheet of basement membrane surrounds each capillary and aids in reducing its permeability. Investigations by Meiners' group indicate that a synthetic polyamide nanofibrillar matrix prepared via electrospinning (Rutledge et al, 2006;Dzenis, 2004) can promote more in vivo-like functions for astrocytes; specifically, astrocytes cultured on nanofibres become more permissive substrates for neurite outgrowth when cultured with an overlay of neurons (Delgado-Rivera et al, 2009). This property increases with the addition of FGF-2.…”

Scanning probe recognition microscopy (SPRM) with auto-tracking of individual nanofibres is used for investigation of the key nanoscale properties of polyamide a nanofibrillar matrix that promotes more in vivo-like forms and functions for cultured cells. Both unmodified and fibroblast growth factor-2-modified nanofibres are considered. The contributions of nanofibrillar matrix elasticity and surface roughness to cellular behaviour are examined.

“…However, reports on the preparation of CNFs from the electrospun precursor fibres are lacking. The diameters of CNFs so far prepared are generally several micrometers to more than 100 nm (Chun et al 1999;Kim and Yang 2003;Li et al 2003;Yang et al 2003;Kim 2004;Kim et al 2004aKim et al , 2007Chung et al 2005;Rutledge et al 2006;Sutasinpromprae et al 2006). In addition, although the aligned CNFs were prepared by rotating the collector (Kim et al 2004b;Rutledge et al *Author for correspondence (msejyu@yahoo.com) 2006) and double-electrode collector , it is necessary to develop simple and new technique for producing the aligned CNFs on large scale at low cost.…”

Ultra thin and aligned carbon nanofibres (CNFs) have been fabricated by heat treatment from aligned polyacrylonitrile (PAN) nanofibre precursors prepared by electrospinning. The alignment of the precursor nanofibres was achieved by using a modified electrospinning set up developed recently, where a tip collector was used to collect and align the nanofibres. The average diameter of the aligned CNFs is about 80 nm. The stabilization and carbonization behaviour were studied mainly based on the randomly oriented PAN nanofibres. The effects of stabilization and carbonization temperatures, temperature-increasing rates, and with and without substrates on the morphology and structure of the CNFs were investigated. Fourier transform infrared spectroscopy, scanning electron microscopy, X-ray diffraction, transmission electron microscopy and Raman spectroscopy were used to characterize the structure of the CNFs and thermogravimetric/ differential temperature analysis was used to evaluate the thermal behaviour of PAN nanofibres.

“…Continuing experiments are focusing on elasticity information acquired in contact mode, to be combined with accurate boundary and surface roughness information acquired in tapping mode. Our group investigates tissue scaffold elasticity using the Force Integration to Equal Limits (FIEL) mapping method to produce a robust measurement of relative elasticity [6,11]. This method has the advantage of being independent of the tip-sample contact point, and of not requiring calibration of the AFM cantilever spring force constant.…”

Atomic Force Microscopes can operate in multiple modes, such as contact, tapping, force-volume, etc., each mode providing different types of information about the test sample. AFM data therefore serves as an ideal candidate for data fusion applications. In practice however, different modes of scanning involve changing the scanning tip, which introduces severe mismatch between the scanned regions. Hence image registration is a key step for aligning the multiple mode data prior to data fusion. This paper presents the registration operation of data from contact and tapping modes with an aim to combine the information for investigating tissue scaffold properties from a cellular perspective.
