“…The encapsulating efficiency of the insulin-loaded LCS-NP complex was found as 48±0.1%, which is reported to be quite high. 22 In the literature, Diebold et al 23 developed and studied LCS-NPs, a class of colloidal system that combines liposomes and CS-NPs as a potential ocular drug delivery system, which had a mean size of from 407.8±9.6 to 755.3±30.0 nm and zeta potential of from +14.7±0.4 to +5.8±1.3 mV.…”

“…84 Entretanto, lipossomas com nanopartículas de quitosana encapsuladas foram capazes de ser internalizados por células de conjuntiva humana (IOBA-NHC). 85 Tal aplicação não comprometeu a viabilidade celular, nem a tolerância após administração in vivo em coelhos, bem como em cortes histológicos de córnea e conjuntiva. 86 Nanopartículas híbridas de quitosana com ácido hialurônico foram capazes de transfectar in vitro células HCE e IOBA-NHC, utilizando diferentes modelos de pDNA como pEGFP (proteína verde fluorescente), pSEAP (fosfatase alcalina) e pLac-Z (β-galactosidase).…”

“…Quanto a sua toxicidade, a quitosana parece ser bem tolerada em aplicações tópicas, 85,86,89 podendo ocorrer o risco de inflamação após administração intraocular de nanopartículas. 91 Ademais, por possuir um pKa de 6,2 as formulações com quitosana podem apresentar certa instabilidade em pH fisiológico (pH 7,4), existindo uma tendência à agregação.…”

“…In vivo studies in rabbits showed that the nanoparticles were well tolerated by the ocular surface structures, which showed no histologic alterations nor abnormal inflammatory cells in cornea, conjunctiva and lids, in full consistency with the lack of clinical signs (de Salamanca et al, 2006). Another potential colloidal drug carrier has been studied, which combines liposomes and Ch nanoparticles (Diebold et al , 2007). The rehydration at 60 °C of a lyophilized mixture of Ch nanoparticles, loaded with FITC-BSA, and liposomes led to the coating of nanoparticles www.intechopen.com with a phospholipid shell.…”
