dc.description.abstract A new fabrication process of organic and inorganic nanoparticles and cups by electrospraying blended polymer -sol -gel solutions followed by calcination has been investigated . Because of low viscosity and high surface tension of blended polymersol - gel solutions , an electrostatically extruded continuous liquid jet from the spray source became tiny droplets with diameter of less than 1 ?m in transit . They were collected as dried formats at the counter electrode . These are then calcinated to eliminate polymers as well as cross -link sol -gel material . Silica nanocups have been fabricated using the above technique and the probable methods to control their morphology by varying the ionic concentration have been investigated . Experiments with biodegradable polymers , like Poly Lactic Acid (PLA ) and polyvinylpyrrolidine (PVP ) to fabricate nanoparticles using the above technique , have also been carried out . The potential use of such biodegradable particles in drug delivery has been demonstrated . This method can encapsulate drug in the particles without the need of any stabilizer which can cause unwanted effect on the drug . The effect of solvents , polymer concentration and deposition distance on morphology and diameter of particles was also investigated on PLA particles . This process is a simple and efficient approach for producing nanocomposite cups that cannot be made by an aggregation method and also nano /micro particles which may find their use in drug delivery and filtration media . Finally , a new technique to sort the particles based on their dimensions is demonstrated . Because of interactions between charged droplets and a non -linear electrostatic field , nanoparticles with different dimensions are deposited at different locations . By using this principle , silica nanocups have been sorted into three groups with mean diameters of 0 .31 ?m , 0 .7 ?m and 1 .1 ?m and a standard deviation of 20 % . en_US
