Abstract
Chitosan is a renewable natural alkaline polysaccharide, and laponite is a multifunctional nanocomposite. Their use exists in several areas, mainly due to their non-toxicity and because chitosan is from natural resources. One primary use in seed coating processes consists of applying an exogenous material to the seeds, which can facilitate handling and planting. Thus, this study aimed to investigate the most appropriate uses in patented and publications related to the use of Laponite and Chitosan to access these materials' state of the art to identify perspectives for new research. One hundred two publications were explored in the scientific databases Scopus (53) and Web of Science (WoS) (79). Of these, duplicates were removed, totaling 93 articles with publications started in 2006. The number of publications on chitosan and laponite for the countries with the highest number of corresponding authors was from China (27), Iran (16), and the United States (15). Brazil also stands out and occupies the fourth position regarding the number of corresponding authors (7). There were prospected 109 patents, and most of them have been used in medical or veterinary hygiene, or hygienic devices and methods (A61K), in cosmetics (A61Q). The compilation and analysis of scientific, technological, and information use carried out in this work has allowed for identifying the new research perspectives and validated the potential use of chitosan and laponite association as a seed coating.
Highlights
Sustainability of products and services has become a compulsory requirement and an essential requirement for organizations, governments, markets, and society in general
With all the properties and benefits, the objective of this work was to search patents and articles that involve the use of chitosan and laponite and their applications in agriculture, especially in seed treatment
Use bibliometric analysis of articles contained in the Scopus and Web of Science databases that were prospected in title or abstract of scientific articles
Summary
Sustainability of products and services has become a compulsory requirement and an essential requirement for organizations, governments, markets, and society in general. The use of laponite and chitosan eco-friendly and commercially is a new challenge to considerer the preconized bioeconomy aiming for sustainable materials In this way, agriculture occupies a third of the earth's surface, moving billions of dollars and generating countless jobs (Rocha et al, 2019) requiring new eco-friendly materials. The growing demand for food, with several people worldwide, above 925 million, and prospects of reaching two billion by 2050 are new challenges Another consideration is the combined features of the climate scenario and conventional practices, which makes it necessary to search for alternatives and develop new technologies that enable agriculture to meet these premises (Ehsanfar and Modarres-Sanavy, 2005; Ma, 2019; Rocha et al, 2019)
