Com.inations of m.tal and lanth.nide oxides h.ve been done th.ough.casted film. for potential m.dical applications. In th.s regard, sam.rium.Ⅲ) oxide/ch.om.um.Ⅲ) oxide/graph.ne oxide(GO)/polycaprolactone(PCL) based film. nano-com.osites(NCs) were fabricated, pointing th.ir utilization as a biological scaffold for wound dressing purposes. Also, sam.rium.Ⅲ) oxide and ch.om.um.Ⅲ) oxide h.ve been m.rged as prom.sing optical constituents due to th.ir unique optical beh.vior. Th. structural and com.ositional exam.nation of th. studied NCs was executed by X-ray diffraction(XRD), Ram.n, and field em.ssion scanning electron m.croscopy(FESEm.. Th. Sm.(2)O_(3)/Cr_(2)O_(3)/GO/PCL NC exh.bits a surface with.a lower rough.ess degree owing to th. presence of GO. Cr_(2)O_(3)sh.ws size reduction upon GO insertion to reach.1.2 μm.as th. average grain size, wh.lst Sm.(2)O_(3)records an average grain size of less th.n 1 μm. As well, th. polym.ric nano-com.ositions exh.bit variation in contact angle values th.t h.t 29.76°± 3.52°for Sm.(2)O_(3)/PCL, and 48.62°± 1.37°for Sm.(2)O_(3)/Cr_(2)O_(3)/GO/PCL as th. second lowest contact angle. Th. optical beh.vior contributes to absorption edge relocation along th. x-axis from.1.7 eV for pure PCL, to 2.65 eV for Sm.(2)O_(3)/Cr_(2)O_(3)/GO/PCL. Regarding biological responses, th. cell exposed to 2.5 μg/m.L of Sm.(2)O_(3)/Cr_(2)O_(3)/GO/PCL sh.ws cell viability of 119.31%, wh.le 5 μg/m.L h.ts 99.6%. Additionally, th. resulting cell attach.ent m.crograph. sh.w layers of fibroblast tissue, besides th. proliferation and growth.of cultivated cells. Th.s, th. Sm.(2)O_(3)/Cr_(2)O_(3)/GO/PCL scaffold provides 3D proliferation of fibroblast cells endorsing th. wound h.aling process.
