A Review on Patents of Starch Nanoparticles: Preparation, Applications, and Development

Background: In this paper, we performed an analysis on how various materials based on starch nanoparticle affect different applications. The frequency of topics related to starch nanoparticles as well as their applications in different patent databases shows the importance of this material. Objective: Being environmentally friendly, these nanoparticles show promise as novel composite biomaterials and are used in industries related to nutrition, paper production and medicines among many others. Results: Our analysis showed that the prevailing synthesis for starch nanoparticles are methods based on acids, enzymes, ultrasonic treatment (alone with its combination with hydrolysis), highpressure homogenization, enzymatic hydrolysis and recrystallization and emulsion-crosslinking. Conclusion: With this review, we provide an update on starch nanoparticles patents and the review can be used by scientists in different fields including nanotechnology.
