“…The former is caused by an increase in hydrogen bonding, and the latter is caused by the higher viscosity of the PVA solution. 33 Because reproducible results and a low polydispersity index with PVA with a degree of hydrolysis of 80% were obtained (Figure 1), this is the stabilizer that is used further on.…”

In local drug delivery, nanoparticles based on biodegradable polymers can function as vehicles with controlled drug-release properties. To achieve a well-controlled drug-release profile, control over the particle size is of great importance. Therefore, biodegradable polyester nanoparticles were prepared by the salting-out method. Process variables were varied to study the effect on the particle size. The monodisperse particles obtained were between 100 and 400 nm in size and spherical in shape. It was found that the particle size could be adjusted by varying the preparation conditions upon which the polymer concentration had the most pronounced effect.

“…PVA is a surface active and water soluble polymer. Although, it does not take part in the chemical reaction, its addition increases viscosity (Briscoe et al 2000) and decreases surface tension (Bhattacharya and Ray 2004) of the solution.…”

CdS nanotubes with wall thickness comparable to excitonic diameter of the bulk material are synthesized by a chemical route. A change in experimental conditions result in formation of nanowires, and well-separated nanoparticles. The diameter and wall thickness of nanotubes measured to be 14.4 ± 6.1 and 4.7 ± 2.2 nm, respectively. A large number of CdS nanocrystallites having wurzite structure constitute these nanotubes. These nanotubes show high energy shifting of optical absorption and photoluminescence peak positions, compared to its bulk value, due to quantum confinement effect. It is proposed that nucleation and growth of bubbles and particles in the chemical reaction, and their kinetics and interactions are responsible for the formation of nanotubes.

“…PVA-80-99 aqueous solution was prepared using the method described by Briscoe et al [17]. In brief, PVA powder was dispersed in distilled water at 25°C for 2 h and this suspension was rapidly heated to above 95°C and kept at this temperature with high speed stirring for about 3 h. The solution was then cooled to room temperature.…”
