Bovine Serum Albumin Case Study

Improved Essays
Bovine serum albumin (BSA) is usually used for generation of nanoparticles (NPs) in drug delivery systems. This paper presents a study on the simple coacervation method for fabrication of BSA nanoparticles.An artificial neural network (ANN) model was developed to predict the diameter of nanoparticles based on experimental data. Effect of pH, temperature, initial BSA and cross linker concentration, molar ratio of BSA to ethanol, agitation rate and rate of ethanol addition were investigated on the protein particle size by ANN. Developedmodel was presented by multilayer perceptron and checked the adequacy of the ANN model by the linear regression analyses. The calculated results were in good agreement with experimental data and developed model …show more content…
Recently, NP has been concerned large attention in the basic research and their application in different fields, where they can be used as electrochemical sensors [7], catalyst [8] , lubricating oils[9], degradation of pollutants[10], drug delivery[11-13] and diagnostics devices[14, 15].
For pharmaceutical use, NPs can be of polymeric nature or be made of lipophilic components plus surfactants, i.e., liposomes, niosomes, and solid lipid NPs. Other materials investigated for NPs preparation are albumin [16], gelatin[17] ,or calcium alginate[18]. There are also several methods available to size-reduce drug substances into the nanometer range, with the produced NPs being stabilized by surfactants[19, 20].

Albumin can form layers on NP, which are stabilized by denaturation of the protein. This denaturation can be introduced by cross-linking agents. Albumin NP have been extensively investigated in our previous study plus in other research teams as suitable carrier for drug delivery vehicles, since they are non-toxic,biodegradable, and non-antigenic[6, 21-23]. Due to their defined primary and high content of charged amino acids (i.e. Lysine) the albumin based NPs could allow electrostatic adsorption of positively or negatively charged molecules without the requirements of other compound

However, in some cases, those models do not apply due to the lack of experimental information or to the complexity of system. Artificial neural networks are being increasingly applied to complement and replace the classical approach whenever necessary [24, 25]. In last two decades, artificial neural network (ANN) has emerged as an attractive tool for non-linear multivariate modeling [26]. Even if the mechanism of reaction is not described clearly, this technique can still predict outputs accurately for a new input data set [27, 28]. The ability of ANNs to learn and generalize the behavior of any complex and non-linear process makes it a powerful modeling tool

    The mild light effect would cause the membrane to accept in the nano-medicine thinking that it was ordinary protein. The one downside to this method is that the siRNA is susceptible to attack and degrading from the lysosomes in the cell but this is where the photothermal nanomaterials come in. It is able to support endosomal escape which would allow a siRNA to escape the captivity of the lysosomes by corrupting its outer protein shell. Thus the siRNA that do escape will be twice as effective because it doesn’t have a lysosome to degrade it…

    N-Vinyl pyrrolidone (NVP) and its copolymers attracting much attention and have been widely investigated for applications in different field due to its low toxicity, biocompatibility and good film forming (Hemalatha et al. 2014; Anasuya; Lee et al. 2007). The amide group in NVP is highly polar, which confirms it’s hydrophilic. NVP has been copolymerized with various monomers because the amide group has high affinity for many large and small molecules that are known to be good hydrogen-bond acceptors (Jin et al. 2013; Santanakrishnan et al. 2012; Arosio et al. 2011). NVP has been copolymerized with various siloxane derivatives monomers such as vinyl triethoxy silane (Gatica et al. 2003), vinyl trimethoxy silane, vinyl trimethyl silane (Gatica et al. 1998),…

    BEMA film was designed to rapidly deliver a drug across the mucosa when fast onset of effect is required and to formulate drugs with poor oral bioavilability[1] Buprenorphine has very poor oral bioavailability(~10%) due to extensive first pass metabolism[3] and hence cannot be formulated as an oral tablet. IM, IV, suppository, transdermal, sublingual and buccal administration routs all bypass first pass metabolism and hence increase the bioavailability however IM, IV or suppositories would be inconvenient to administer regularly therefore only transdermal, sublingual and buccal formulations are suitable dosage forms for treatment of opioid dependence. Transdermal administration of buprenorphine has an absolute bioavailability of approximately…

    The wavelength selected for analysis was 265nm to reduce baseline noise at absorption maximum (257nm) of Tamoxifen citrate. Mobile phase composition or solvent strength plays an important role in RP-HPLC. An HPLC column packed with stationary phase of octadecyl carbon chain (C18)-bonded silica was used. A polar mobile phase such as mixture of organic solvent methanol and buffer was used. The hydrophobic molecules in the polar mobile phase show more affinity to the hydrophobic stationary phase and these molecules can be eluted from the column by decreasing the polarity of the mobile phase for reducing hydrophobic interactions.…
