Development of radioimmunoassay

Therapeutic monitoring of theophylline can be accurately performed by radioimmunoassay (RIA). It is radioactive tracer as an essential reagent for the development of very sensitive RIA. Direct radiolabeling of theophylline with¹²⁵I is very difficult due to the absence of appropriate functional groups. Hence carboxylic acid of theophylline was tagged to tyrosine methyl ester and then radiolabeled. The derivatives of theophylline, bearing a propionic acid and butyric acid side chains at seventh and eight position of theophylline, were synthesised and coupled to tyrosine methyl ester. Theophylline-tyrosine methyl ester conjugates were labeled with¹²⁵I using chlora mine—T. Radiolabeled theophylline was purified by solvent extraction followed by thin layer chromatography. The purified radiolabeled compound were assessed for their radiochemical purity, specific activity and immunoreactivity. Stability studies of radiolabeled compounds were performed with different solvents at different temperatures. Theophylline serum samples analysed using developed and commercial kits showed the correlation coefficient of 0.961 (n=9).

Development of Bionic Polymers

Bionics, an artificial imitation of natural products, has always been a forever dream in the fairy tale or scientific fiction when we were childhood and children live now. However, the development of science in molecular scale makes this dream of childhood and manhood realize today.Bionics, a branch of science concerned with application the data about the functioning of biological system to the solution of engineering problems, become top-priority of science in the 21st century.However, few examples are given in molecular-level or nano-scale controlling lotus-like surface (a bionic surface for vast potential application). In the same time, such a typical bionic surface (as well known, so called "Lotus-effect") is a symbol or a totem that scientists can develop a novel approach to prepare desired surface and to control its microstructure or morphology at one's pleasure.In general, a film with a water contact angle (CA) higher than 150° can be defined as a superhydrophobic surface. The Langmuir-Blodgett film prepared by using CF3(CF2)10COOH possesses the lowest surface tension, which is 6 mJ/m2 (1). However, the water CA on a smooth surface with regularly aligned C20F42 with close-hexagonal packed -CF3 groups is only 119° (2).Obviously, only adjusting chemical composition is not enough to produce a superhydrophobic surface. Wenzel et al (3) suggested that the contact angle θ' of a liquid droplet on a rough solid surface should be written as:cosθ, =γcosθ = γ(γs-γsl)/γl, here γ is a roughness factor and γsl, γs and γl denote the interfacial tensions of the solid-liquid, the solid-gas, and the liquid-gas interfaces,respectively. This γ is always larger than 1 and a rough surface will be more water-repellent or more wettable to a liquid when intrinsic contact angle θ is bigger or smaller than 90°, respectively.Therefore, a general approach to obtain superhydrophobic surfaces is using a combination of depressing surface energy and enhancing surface roughness (4-17).Super-hydrophobic polymeric surface has been prepared in this case with a mixture of low-cost fluorine-end-capped polyurethane(FPU) and commonly available polymethyarylates(PMA) under ambient conditions. No obvious structures were observed by SEM for the pure FPU coated surface.The surface morphology is uniformly smooth at both low and high magnifications. The CA on the surface is about 95°, which indicates that FPU film has better hydrophobicity than pure polyurethane without fluorine-group, whose CA is about 65°. However, the hydrophobicity of polymer surface changes dramatically as the film is directly prepared through a one-step coating of a FPU/PMA solution between 10-30℃. The CA is up to 166 . The result shows that the SA can be dramatically decreased with small amount of FPU, and the SA reached a limiting value of 3.4 ± 2.0 ° when the FPU content in the FPU/PMA mixture is between 20 ～ 60 wt%. The water drop is unstable on these surfaces, and with a very small tilt-angle, the water drop will roll off the surface.It means that such a polymeric surface exhibits an excellent superhydrophobicity. In addition, the polymer surface possesses not only a better hydrophobicity than that of natural lotus leaf (CA measured is about 160°), but also a lypophobic property: the oil contact angle on the same surface is 140°, while the surface of lotus is lypophilic. Most interestingly, we have found that the coated film prepared by FPU/PMA mixture has a two-length scaled rough micro-nano-binary structure, that is, every micro-papilla (300-700nm) on the polymeric surface is also covered by nano-papillae ranging from 30-40nm. These MNBs is very much the same as the natural lotus-leaf surface in micro- and nano-scales. Compared with lotus surface structure, the NMBs structure on this bionic polymeric surface prepared is in less scale. The results clearly demonstrated that a bionic polymeric surface similar to the natural lotus-leaf surface can be obtained by a one-step coating process. The results showed also that such a bionic polymeric surface possess of some "self-repairing" properties similar to that of natural surfaces and the effects of preparation temperature and concentration as well as substrate made no obvious difference on the hydrophobicity of the bionic polymeric surfaces..In conclusion, we demonstrated that the MNBs of a bionic polymeric film has been one-step obtained with the use of the self-aggregation of PMA combining with a nano-scaled phase separation of amphiphilic copolymer during the drying process in ambient atmosphere. This remarkable result provides many potential possibilities, including coating, hygienic, medical,environmental, and industrial processing applications.
