The role of nitric oxide (NO) as a vasodilator has long been established. Due to the high reactivity and a lack of a practical delivery system for gaseous NO, its applicability has been limited. In this study, we examine the adsorption of the NO within molecular sieves and demonstrate the ability to fabricate composite materials in the form of electrospun fibrous bandage that can release NO with a controlled rate and in physiological relevant doses. The use of the NO releasing fibers for the preservation of transplant organs was demonstrated on rat hearts. © 2010 American Chemical Society.

Gold nanoparticles (AuNP) were formed in situ, while electrospinning a polyacrylonitrile (PAN) solution of HAuCl 4 under UV light without using heat or chemical reducing agents. The resulting fibers were purple in color due to the formation of AuNP inside and on the surface of the nanofibers. TEM images showed spherical and uniformly dispersed particles inside the polymer fibers. The concentration of Au + 3 in the PAN solution is directly proportional to the size of the generated particles, with average diameter of 21.4 nm and 5.8 nm for the 0.044 M and 0.022 M solutions, respectively. © 2012 Elsevier B.V.
