“…It has been used for sensing paraoxon interacting with LbL films of chitosan and OPH (organophosphorous hydrolase) (Constantine et al, 2003), and for antibodies interacting with LB films of viologen and protein-A (Lee et al, 2004). Sensors for integrin were based on its interaction with hybrid LbL-LB films made with lipid dye labeled receptors and streptavidin (Worsfold et al, 2004).…”

Various modes are being explored for the construction of functional materials from nanoparticles. Despite these efforts, the assembly of nanoparticles remains challenging with respect to the requirement of multiple component organization on varying dimensions and length scales. The graft copolymers of chitosan with poly(butylene glycol adipate) (PBGA) were prepared due to the esterification reaction between PBGA and 6-O-succinate-N-phthaloyl-chitosan (PHCSSA) in the presence of toluene as a swelling agent. The graft copolymers are nanoparticles with the size of few hundred nanometers as observed from TEM. It is a potential method to combine chitosan with the hydrophobic synthetic polymers. The grafting reactions were conducted with various PBGA/PHCSSA feed ratios to obtain chitosan-g-PBGA copolymers with various PBGA contents. FT-IR, NMR, XRD, spectrofluorophotometer, and TEM were detected to characterize the copolymers.

OverviewA critical issue to homeland security and defense is the development of broad range collectors and detectors of weapons of mass destruction. Nanoscience and nanotechnology are increasingly important in the area of such separation and detection. This article presents an overview of the research at the Forensic Science Center at Lawrence Livermore National Laboratory to develop nanostructured materials for applications to forensics and homeland security. Among the many types of nanomaterials reviewed are silica-based materials, molecular imprinted polymers, and silicon platforms. The main aim of the article is to optimize these new classes of materials for the collection concentration and detection of chemical weapons or other related compounds.
