Preparation of human serum albumin nanoparticles using a chemometric technique

Human serum albumin (HSA), a versatile protein carrier for drug delivery, is an ideal material to fabricate nanoparticles for drug delivery systems. These nanoparticles can accumulate in tumor interstitium due to the enhanced permeability and retention effect. The most important characteristics of HSA nanoparticles are particle size, shape, and zeta potential. A chemometric approach was applied for HSA nanoparticles' size optimization in this study. The effects of three experimental parameters; pressure (P) or power, organic solvent volume (V), and time (T), were investigated under sonication and high-pressure homogenization, using multivariate analysis. The trials were performed based on the Box-Behnken experimental design. The criteria for the appraisal of the descriptive ability of a multinomial were R 2 = 0.819, standard error = 20.420, and F-ratio = 19.550. The method was optimized with respect to the nanoparticles' size as a response. The Box-Behnken experimental design was applied to optimize and trial the robustness of the HSA nanoparticle preparation method.

African Journal of …, 2010

Bovine serum albumin (BSA) was used for generation of nanoparticles in a drug delivery system. The size of the fabricated nano-particles was measure by laser light scanning. Several process parameters were examined to achieve a suitable size of nanoparticle such as pH, temperature, BSA concentration, agitation speed, glutaraldehyde concentration, organic solvent adding rate and the ratio of BSA/organic solvent. The smallest size of nanoparticles achieved, was 101 nm and the largest size was 503 nm. The most effective parameters for the fabrication of the nanoparticles were the agitation speed and the media temperature. The minimum size of nanoparticles at the desired incubator of 4°C and constant agitation rate of 300-400 rpm was obtained. The impact of protein concentration and additional rate of organic solvent (i.e. ethanol) upon the particle size was investigated. The protein concentration of 5-40 mg.ml-1 was resulted; the main effect on the particle size and minimum mean size diameter gained was 30 mg.ml-1 protein concentration. The nanoparticle sample was purified with 50,000 g centrifuge then followed by dialysis, micro and ultrafiltration and then analyzed by SEM, PCS as well as SDS gel electrophoresis.

Human Serum Albumin (HSA) Nanoparticles as Drug Delivery System: Preparation, Optimization and Characterization Study

Nanoparticles (NPs) have been developed as an important strategy to deliver low molecular-weight drugs, as well as biomacromolecules such as proteins or DNA. The body distribution of colloidal drug delivery systems was mainly influenced by two physicochemical properties namely particle size and surface characteristics. Particle size is a crucial parameter, in particular for the in vivo behavior of NPs after intravenous injection. The objective of the present study was the preparation of human serum albumin (HSA) nanoparticle (NP) by desolvation method and optimization of NP by applying the Taguchi method together with characterization of the NP bioproducts for drug delivery application. Several process parameters were examined to achieve a suitable size of NP such as pH, HSA concentration, organic solvent adding rate and the ratio of organic solvent/HSA solution. Taguchi method with L 16 orthogonal array robust design was implemented to optimize experimental conditions of the purpose. This approach facilitates the study of interaction of a large number of variables spanned by factors and their settings with a small number of experiments leading to considerable saving in time and cost for the process optimization. As a result of Taguchi analysis in this study, pH and ratio of organic solvent/HSA solution were the most influencing parameters on the particle size. The minimum size of NPs (53 nm) were obtained at pH 9, 75 mg.ml-1 HSA concentration, ratio of organic solvent/HSA solution of 4 and organic solvent adding rate of 1.5 ml.min-1. The mechanistic of the optimum conditions for preparing protein NPs and their characterization as drug delivery vehicles are discussed.

Human Serum Albumin Nanoparticles for Use in Cancer Drug Delivery: Process Optimization and In Vitro Characterization

Human serum albumin nanoparticles (HSA-NPs) are widely-used drug delivery systems with applications in various diseases, like cancer. For intravenous administration of HSA-NPs, the particle size, surface charge, drug loading and in vitro release kinetics are important parameters for consideration. This study focuses on the development of stable HSA-NPs containing the anti-cancer drug paclitaxel (PTX) via the emulsion-solvent evaporation method using a high-pressure homogenizer. The key parameters for the preparation of PTX-HSA-NPs are: the starting concentrations of HSA, PTX and the organic solvent, including the homogenization pressure and its number cycles, were optimized. Results indicate a size of 143.4 ˘ 0.7 nm and 170.2 ˘ 1.4 nm with a surface charge of´5.6 ˘ 0.8 mV and´17.4 ˘ 0.5 mV for HSA-NPs and PTX-HSA-NPs (0.5 mg/mL of PTX), respectively. The yield of the PTX-HSA-NPs was ~93% with an encapsulation efficiency of ~82%. To investigate the safety and effectiveness of the PTX-HSA-NPs, an in vitro drug release and cytotoxicity assay was performed on human breast cancer cell line (MCF-7). The PTX-HSA-NPs showed dose-dependent toxicity on cells of 52%, 39.3% and 22.6% with increasing concentrations of PTX at 8, 20.2 and 31.4 µg/mL, respectively. In summary, all parameters involved in HSA-NPs' preparation, its anticancer efficacy and scale-up are outlined in this research article.

Albumin nanostructures as advanced drug delivery systems

Expert opinion on drug delivery, 2016

One of the biggest impacts that the nanotechnology has made on medicine and biology, has been in the area of drug delivery systems (DDSs). Many drugs suffer from serious problems concerning insolubility, instability in biological environments, poor uptake into cells and tissues, sub-optimal selectivity for targets and unwanted side effects. Nanocarriers can be designed as DDSs to overcome many of these drawbacks. One of the most versatile building blocks to prepare these nanocarriers is the ubiquitous, readily available and inexpensive protein, serum albumin. This review covers the use of different types of albumin (human, bovine, rat, and chicken egg) to prepare nanoparticle and microparticle-based structures to bind drugs. Various methods have been used to modify the albumin structure. A range of targeting ligands can be attached to the albumin that can be recognized by specific cell receptors that are expressed on target cells or tissues. The particular advantages of albumin used...

Journal of Controlled Release, 2012

Albumin, a versatile protein carrier for drug delivery, has been shown to be nontoxic, non-immunogenic, biocompatible and biodegradable. Therefore, it is ideal material to fabricate nanoparticles for drug delivery.

Albumin‐based nanocomposite spheres for advanced drug delivery systems

A novel drug delivery system incorporating human serum albumin, poly(lactic-co-glycolic acid, magnetite nanoparticles, and therapeutic agent(s) was developed for potential application in the treatment of diseases such as rheumatoid arthritis and skin cancer. An oil-in-oil emulsion/solvent evaporation (O/OSE) method was modified to produce a drug delivery system with a diameter of 0.5-2 μm. The diameter was mainly controlled by adjusting the viscosity of albumin in the discontinuous phase of the O/OSE method. The drug-release study showed that the release of drug and albumin was mostly dependent on the albumin content of the drug delivery system, which is very similar to the drug occlusion-mesopore model. Cytotoxicity tests indicated that increasing the albumin content in the drug delivery system increased cell viability, possibly due to the improved biocompatibility of the system. Overall, these studies show that the proposed system could be a viable option as a drug delivery system in the treatment of many illnesses, such as rheumatoid arthritis, and skin and breast cancers.
