“…Nanosynthesis controlling the size, shape, structures and morphology was used thoroughly for lanthanide nanophosphors in the form of nanoparticles or nanorods [35]. Nanoparticle YVO 4 : Eu(III) was synthesized by several techniques in an aqueous solution such as coprecipitation or in the presence of soft template [36,37]. Nanosized core/shell Eu.NTA.TOPO@PVP or silica was prepared with vortex technique in colloidal solvent system at room temperature [38].…”

“…The successful synthesis of a nanosized metalorganic complex having the active rare earth mixing ions Tb and Eu with high quantum yield emission, high photostability and their good water solubility provides promising research for biomedical photonic engineering. [37], TbPO 4 • H 2 O [36,39] and Eu X Tb 1−X PO 4 • H 2 O nanorods and nanowires [40]. From the FE-SEM images, one can estimated that the mean size of the EuPO 4 • H 2 O nanorods is about 15-20 nm in diameter and 300-500 nm in length.…”

We report for the first time the preparation of luminescent lanthanide nanomaterial (LLN) linked bioconjugates and their application as a label tool for recognizing virus in the processing line of vaccine industrial fabrication. Several LLNs with the nanostructure forms of particles or rods/wires with europium (III) and terbium (III) ions in lattices of vanadate, phosphate and metal organic complex were prepared to develop novel fluorescent conjugates able to be applied as labels in fluorescence immunoassay analysis of virus/vaccine.With regard to the LLNs, we have successfully synthesized nanoparticles around 10 nm of YVO 4 : Eu(III), with high emission in the red spectral region, nanorod and nanowire of TbPO 4 • H 2 O and Eu 1−x Tb x PO 4 • H 2 O, width 5-7 nm and length 300 nm, showing very bright luminescence in green, and core/shell nanosized Eu(III) and Tb(III)/Eu(III) complexes with naphthoyl trifluoroacetone and tri-n-octylphosphineoxide (Eu.NTA.TOPO@PVP, Eu X Tb 1−X .NTA.TOPO). The appropriated core/shell structures can play a double role, one for enhancing luminescence efficiency and another for providing nanophosphors with better stability in water media for facilitating the penetration of nanophosphor core into a biomedical environment.The organic functionalizations of the obtained LLNs were done through their surface encapsulation with a functional polysiloxane including active groups such as amine (NH 2 ), thiocyanate (SCN) or mecarpto (SH). The properties of functional sol-gel matrix have great influence on the luminescence properties, especially luminescence intensity of YVO 4 : Eu(III), Eu.NTA.TOPO@PVP, TbPO 4 • H 2 O and Eu x Tb 1−x PO 4 • H 2 O. Bioconjugation processes of the functionalized LLNs have been studied with some bioactive molecules such as biotin, protein immunoglobulin G (IgG) or bovine serum albumin (BSA).The results of LLN-bioconjugate linking with IgG for recognizing virus (vaccine) will be presented in brief. It is consistent to state that the LLN bioconjugates prepared from YVO 4 : Eu(III)-nanoparticles, TbPO 4 • H 2 O nanorod or wire and EuNTA.TOPO@PVP nanosized core/shell complex could be used as labels for recognizing virus in diagnosis or in vaccine production by use of the fluorescence immunoassay (FIA) method. The fluorescence images of the incubated specimens consisting of LLN bioconjugate and vaccine fabricate could be obtained well in terms of sharpness, reproductivity and stability.

“…With the reaction proceeding, the sacrificial template is gradually consumed during the shell‐forming process. The resultant shell forms outside the template and takes the shape of the template, reserving the spherical shape [9]. If the sacrificial template is partly consumed, the core–shell structure with a distinctive core@void@shell configuration, which is usually called yolk–shell or rattle‐type structures.…”

Submicrometre-sized EuPO 4 hollow spheres were synthesised by utilising the colloidal spheres of Eu(OH)CO 3 as the sacrificial template, for the first time. The EuPO 4 hollow spheres were investigated by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and photoluminescence, respectively. The EuPO 4 hollow spheres exhibit red colour emission from 5 D 0-7 F J (J = 1, 2, 3, 4) transitions of the Eu 3+ ions. The obtained EuPO 4 hollow spheres may have potential applications in cell biology, drug release, diagnosis, due to the high chemistry stability and luminescence function.

“…4,5,16 In previous studies, we have been successful in synthesizing nanorods/nanowires of EuPO 4 , and TbPO 4 . 17,18 It was found that the size and shape of the products have important effects on their luminescent intensity. However, nano-sized materials with high luminescent yields are still required for medical and biological applications.…”
