The preliminary results obtained have demonstrated the feasibility of the FIM concept presented. Micro fluidic injectors and diodes represent an alternative approach to the microfluid handling and may be very useftil with respect to dosing fluid in nanoliter range. 

In conclusion, on the basis of these preliminary results, the transformation of the bile acids examined, which was generally faster in treated patients, appears to be correlated to the number of micro-... 

As seen in the SEM image, Figure 6, the embossed feature with micro-cellular foaming has no flash. In these preliminary results, the foaming level was too high to allow for fiill consolidation at the feature surface as evident as surface roughness. However, it is seen that there is no flash with the foamed substrate while with standard PS, there is significant flash. 

As a suitable model reaction, the coupling of various substituted carboxylic acids to polymer resins has been investigated by Stadler and Kappe (Scheme 7.8) [28]. The resulting polymer-bound esters served as useful building blocks in a variety of further solid-phase transformations. In a preliminary experiment, benzoic acid was attached to Merrifield resin under microwave conditions within 5 min (Scheme 7.8 a). This functionalization was additionally used to determine the effect of micro-wave irradiation on the cleavage of substrates from polymer supports (see Section 7.1.10). The benzoic acid was quantitatively coupled within 5 min via its cesium salt utilizing standard glassware under atmospheric reflux conditions at 200 °C. 

Although these results are preliminary, they demonstrate the feasibility of the concept of photocatalytic microstructured reactors, and their potential to increase by various orders of magnitude the catalyst coated surface per reaction liquid volume [124[. A critical problem to solve is the maximization of the illumination efficiency. The availability of a multitude of low-intensity light emitting sources on the micro- or even nanoscale near the catalyst particles appears to be a novel and promising approach to achieve uniform and maximized illumination. Combination of the latter approach with equipment to overcome the mass transfer limitations may prove to be the significant improvement that photoreactors need for industrial implementation. 

Leuprolide acetate, a synthetic nonapeptide, is prescribed for the treatment of metastatic prostate cancer and endometriosis. Leuprolide acetate is presented in a number of injectable dosage forms including Lupron sterile solution for subcutaneous administration (1 and 5 mg mL 1) and Lupron depot controlled release formulation for intramuscular injection (3.75 and 7.5 mg). Zheng and Fulu [106] have evaluated the in vivo effect of leuprolide loaded micro emulsions on the genital organs of the male and female rats. In the preliminary pharmacokinetic studies, oral microemulsions of leuprolide administration resulted in 10-fold higher plasma levels of leuprolide as compared to that of saline solution (Fig. 9.4). 

Abstract In this perspective article, we introduce a potentially transformative DNA/RNA detection technology that promises to replace DNA microarray and real-time PCR for field applications. It represents a new microfluidic technology that fully exploits the small spatial dimensions of a biochip and some new phenomena unique to the micro- and nanoscales. More specifically, it satisfies aU the requisites for portable on-field applications fast, small, sensitive, selective, robust, label- and reagent-free, economical to produce, and possibly PCR-free. We discuss the mechanisms behind the technology and introduce some preliminary designs, test results, and prototypes.
