    This project offers knowledge on creating and putting in place a pharmaceutical management system. And here, the major objective is to increase the efficacy, efficiency, and accuracy of the drug. In today's world, management is one of the most crucial organizational components. Additionally, complexity is added when management does a certain activity in any way. In other words, the availability of computers and advancements in information technology have made it possible for us to swiftly and effectively gather and communicate vast volumes of data on patient treatment. The pharmacy management system should be able to get prescriptions and non-prescription medications with the assistance of certified, trained pharmacists in order to provide patients with the medications they require. Today, many of these types of pharmacy management systems are used to better manage pharmacy-related activities

    Interfacial Molecular Imprinting in Nanoparticle-Stabilized Emulsions

    A new interfacial nano and molecular imprinting approach is developed to prepare spherical molecularly imprinted polymers with well-controlled hierarchical structures. This method is based on Pickering emulsion polymerization using template-modified colloidal particles. The interfacial imprinting is carried out in particle-stabilized oil-in-water emulsions, where the molecular template is presented on the surface of silica nanoparticles during the polymerization of the monomer phase. After polymerization, the template-modified silica nanoparticles are removed from the new spherical particles to leave tiny indentations decorated with molecularly imprinted sites. The imprinted microspheres prepared using the new interfacial nano and molecular imprinting have very interesting features: a well-controlled hierarchical structure composed of large pores decorated with easily accessible molecular binding sites, group selectivity toward a series of chemicals having a common structural moiety (epitopes), and a hydrophilic surface that enables the MIPs to be used under aqueous conditions

    A low cost novel sensing system for detection of dangerous marine biotoxins in seafood

    No full text
    A novel planar interdigital sensor-based sensing system has been developed for detection of dangerous marine biotoxins in seafood. Our main objective is to sense the presence of dangerous contaminated acid in mussels and other seafood by observing the change of reactive impedance of the planar interdigital sensors. Initial studies were conducted with three peptide derivatives namely sarcosine, proline and hydroxylproline. These three chemicals are structurally closely related to our target molecule. The proline molecule is arguably the most important amino acid in peptide conformation, contains the basic structural similarity to the domoic acid. Three novel interdigital sensors have been designed and fabricated. All sensors have the same effective area but having different sensor configurations. The initial results show that sensors respond very well to the chemicals and it is possible to discriminate the different chemicals from the output of the sensor. The sensors were also being tested with three seafood products. Results from the analysis have shown that one configuration has better sensitivity compared to other configurations. The sensor with the best sensitivity was chosen for experiment using proline and mussels. The changes in sensor sensitivity were analyzed with mussels before and after adding the proline. The presence of proline on the mussel surface and also injected proline to the mussels was very clearly detected by the sensor. Further experiment was conducted with small amount of domoic acid (0.5–5.0 μg) injected to a mussel and it was found that the chosen sensor was able to detect small amount of domoic acid (1.0 μg) injected into the mussel sample. The result shows that the sensor was able to detect approximately 12.6 μg/g of domoic acid in mussel meat. The outcomes from the experiments provide chances of opportunity for further research in developing a low cost miniature type of sensors for reliable sensing system for commercial use.9 page(s

    A planar interdigital sensor-based sensing system has been fabricated for assessment of seafood quality. Our main objective is to sense the molecule of domoic acid presence in mussels. Three peptide derivatives namely sarcosine, proline, and hydroxylproline were used for the initial studies which are structurally closely related to our target molecule. The proline molecule is arguably the most important amino acid in peptide conformation, containing the basic structural similarity to the domoic acid. Three novel interdigital sensors have been designed and fabricated. The initial result shows that sensors respond very well to the chemicals and it is possible to discriminate the different chemicals from the output of the sensor. Results from the analysis have shown that Sensor_1 has better sensitivity compared to other sensors. Sensor_1 was chosen for further analysis with real mussels. The changes in sensor impedance were then analysed with real mussels before and after adding the proline. The presence of proline on the mussel samples was detected by the sensor. Results also showed a good correlation of 2 = 0.717 between sensitivity and sample thickness

    Donor-π-Conjugated Spacer-Acceptor Dye-Sensitized Solid-State Solar Cell Using CuI as the Hole Collector

    Dye-sensitized solid-state solar cells (DSSCs) replacing the liquid electrolyte with a p-type semiconductor have been extensively examined to solve the practical problems associated with wet-type solar cells. Here, we report the fabrication of a solid-state solar cell using copper iodide (CuI) as the hole conductor and alkyl-functionalized carbazole dye (MK-2) as the sensitizer. A DSSC sensitized with MK-2 showed a solar-to-electrical power conversion efficiency of 3.33% with a Voc of 496 mV and a Jsc of 16.14 mA cm-2 under AM 1.5 simulated sunlight. The long alkyl chains act as a barrier for charge recombination, and the strong accepting and donating abilities of the cyanoacrylic and carbazole groups, respectively, enhance the absorption of light at a longer wavelength, increasing the short-circuit current density. The efficiency recorded in this work is higher than similar DSSCs based on other hole collectors
