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
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.
