The zeta potential of the best chitosan preparation was found to be 37.79, which confirms the stability of prepared nanosuspension.\u0000\u0000\u0000CONCLUSION\u0000Nanoparticles with small particle size found to have high encapsulation efficiency and relatively high loading capacity and predetermined in vitro release profile.","PeriodicalId":20960,"journal":{"name":"Recent patents on inflammation & allergy drug discovery","volume":"11 1 1","pages":"41-52"},"PeriodicalIF":4.2,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42392467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
