2.10. Stability studies
2.10.1. Storage stability
Doxorubicin loaded nanoparticles were stored at 4 ◦C and were studied for particle size, zeta potential and drug content up to 1 month. Particle size and zeta potential were determined by particle size analyzer and DOX content was determined using UV/vis spectrophotometer.
2.10.2. Effect of pH and ionic concentration of medium
For the determination of effect of pH on the stability, DXGP were incubated in different pH medium (pH 3–11). Nanoparticles incubated in phosphate buffer saline pH 7.4 were taken as control. Absorbance was measured after 24 h and compared with absorbance of control. The effect of ionic strength on the stability of DXNP was determined by incubating the nanoparticles in deionised water containing varying concentrations (0.1–2 M) of sodium chloride
(NaCl).
2.10.3. Serum stabilityof DXGP
Serum stability of DXGP was evaluated at two different serum concentration levels (10%, v/v, and 100% serum). Nanoparticles were dispersed in serum and particlessize, zeta potential and absorbance were measured at different time intervals up to 72 h.
2.11. Statistical analysis
All the experiments were performed in triplicates. Data are expressed as Mean ± SD (standard deviation) (n = 3). The values of in vitro drug release, cytotoxicity and stability studies were statistically analyzed using student’s t-test. Statistical significance levelwas set at p < 0.05.
3. Result and discussion
3.1. Preparation and optimization of gold nanoparticles Gold nanoparticles were prepared by chemical reduction method using xanthan gum as reducing agent. The role of gumconcentration was studied by using gum solution in the range of 0.5–2 mg/ml containing 10 mM of HAuCl4 concentration (Fig. 1a).
The absorbance in the UV spectrum which describes the reduc-
tion of GNP, was found to be directly related to gum concentration.
The intensity of the absorption band gradually increased and the
maximum intensity of absorption was attained at 1.5 mg/ml which
indicated the maximum gold nanoparticle concentration.

这是百度翻译的吧。基本上没有逻辑性啊~
