“…When the film is adsorbed on the DODAB, the increment is about 0.5 ± 0.18 nm per layer whereas multilayers adsorbed on diblock PS-b-PAA present a larger increment: 1 ± 0.2 nm per one layer. Moreover, one notices an irregularity for the two first layers before a significant increase of the thickness sets in, as already reported by Hong et al [34]. The architecture of the two systems seems to be different.…”

“…While the UV–Vis spectrum is complicated by scattering, the Cy-5 peak observed at 650 nm in solution shifted by only 5 nm after surface confinement indicating minimal changes in the local microenvironment (Appendix A, Supplementary data Fig. S6) (Hong et al, 1997; Clontech, 2008). The apparent extinction coefficient, ε , for the Cy-5 dye Zhang and Dong, 2006; is approximately 2.5 × 10 5 M −1 cm −1 and the absorbance at λ max indicates that the quantity of Cy-5 on the dendrimer coupled ruthenium coated silica spheres was 1.3 μmol.…”

Ink jet printed carbon nanotube forest arrays capable of detecting picomolar concentrations of immunoglobulin G (IgG) using electrochemiluminescence (ECL) are described. Patterned arrays of vertically aligned single walled carbon nanotube (SWCNT) forests were printed on indium tin oxide (ITO) electrodes. Capture anti-IgG antibodies were then coupled through peptide bond formation to acidic functional groups on the vertical nanotubes. IgG immunoassays were performed using silica nano particles (Si NP) functionalized with the ECL luminophore [Ru(bpy)2 PICH2]2+], and IgG labelled G1.5 acid terminated PAMAM dendrimers. PAMAM is poly(amido amine), bpy is 2,2′-bipyridyl and PICH2 is (2-(4-carboxyphenyl)imidazo[4,5-f][1,10]phenanthroline). The carboxyl terminal of [Ru(bpy)2 PICH2]2+ (fluorescence lifetime ≈682 ± 5 ns) dye was covalently coupled to amine groups on the 800 nm diameter silica spheres in order to produce significant ECL enhancement in the presence of sodium oxalate as co-reactant in PBS at pH 7.2). Significantly, this SWCNT-based sensor array shows a wide linear dynamic range for IgG coated spheres (106 to 1012 spheres) corresponding to IgG concentrations between 20 pM and 300 nM. A detection limit of 1.1 ± 0.1 pM IgG is obtained under optimal conditions.

“…MIPC fibers have been predicted to have a great use in biomedical applications especially of model system for cell biology and there are also used as basic components for the fabrication of human organs and tissues. IPC fibers are also used as drug delivery devices, light emitting diode and antireflection coating . Syringe pumps and microfluidic channels are not required by this method .…”

Microfibers have received much attention due to their promise for creating flexible and highly relevant tissue models for use in biomedical applications such as 3D cell culture, tissue modeling, and clinical treatments. A generated tissue or implanted material should mimic the natural microenvironment in terms of structural and mechanical properties as well as cell adhesion, differentiation, and growth rate. Therefore, the mechanical and biological properties of the fibers are of importance. This paper briefly introduces common fiber fabrication approaches, provides examples of polymers used in biomedical applications, and then reviews the methods applied to modify the mechanical and biological properties of fibers fabricated using different approaches for creating a highly controlled microenvironment for cell culturing. It is shown that microfibers are a highly tunable and versatile tool with great promise for creating 3D cell cultures with specific properties.
