Size-controlled synthesis and characterization of fluorapatite nanocrystals in the presence of gelatin

Precipitation of biomimetic fluorhydroxyapatite/polyacrylic acid nanostructures

“…Conventional surfactants have been widely used, such as polyacrylic acid (PAA), EDTA, and sodium dodecyl sulfate (SDS) [25,26,[28][29][30][31][32][33][34][35][36][37]. Others have taken a more biomimetic approach using gelatin, collagen, and various organic acids [27,[38][39][40][41][42][43].…”

“…Tao et al [41] showed how spherical HA nanoparticles could be assembled into either plates or rods in the presence of glutamic acid or glyceine; selective adsorption of the biological components directed the assembly of the nanoparticles, and an amorphous surface layer on the HA first bound the particles together and then crystallised, so that the separate particles formed a continuous crystal. Spherulites and 'dandelion-like' structures of HA and FA have been prepared in the presence of gelatin and EDTA [30,34,39,44] and control of the size and aspect ratio of dispersed nanoparticles has been achieved by several routes [25,40,45].…”

Effects of crystalline growth on structural and luminescence properties of Ca(10−3x)Eu2x(PO4)6F2 nanoparticles fabricated by using a microwave driven hydrothermal process

“…Furthermore, this essential microelement is necessary for the normal dental and bone formation in living systems 13,14 . In response to the consumption of fluorinated water CaFAp is formed on the outer layer of the tooth 15 . In vitro studies have confirmed biocompatibility of calcium fluorapatite and have shown release of F -ions in a controlled rate.…”

“…In vitro studies have confirmed biocompatibility of calcium fluorapatite and have shown release of F -ions in a controlled rate. Moreover, it has been demonstrated that it exhibits integration with hard tissue and longer resorption time that ordinary CaHAp 12,13,15 . Due to these advantages fluorapatite is considered as a biological material and as a fluorescence bioprobe for bio-imaging and biosensing.…”

Mesoporous Carbon in the Global World

“…Tahun 2003 untuk pertama kali berhasil mensintesis CMK-8 dan CMK-9 menggunakan KIT-6 sebagai cetakan [5], [7], [9], [69]- [71]. KIT-6 disintesis dari campuran triblok kopolimer-butanol sebagai agen pengarah struktur menghasilkan silika mesopori tipe batang dan tabung dengan simetri kubus Ia3d [16], [7], [10], [34] CKT-1 semi heksagonal [88] CKT-2 disorder cubic [89] C-125 semi batang inner-outer [90] CMM semi sangkar pori ganda [91] CSS Seminkubus [92] CP-1 sangkar kubus [93] OMCG sangkar semi kubus [94] Ada dua macam teknik sintesis karbon mesopori yaitu cetakan padat dan cetakan lunak. Cetakan padat menggunakan padatan berpori sebagai tempat pengendapan prekursor karbon [20], [77], [78], [57], [61], [79], [80], sedangkan cetakan lunak menggunakan surfaktan sebagai agen pengarah struktur [25], [59], [67], [70], [81]- [86].…”
