Functionalization of PEG—PMPC-based polymers for potential theranostic applications
Frontiers of Materials Science - - 2021
Ning Chen, Sidi Li, Xueping Li, Lixia Long, Xubo Yuan, Xin Hou, Jin Zhao
The synergistic effect of polyethylene glycol (PEG) and poly(2-methacryloyloxyethyl phosphorylcholine) (PMPC) can effectively reduce the protein absorption, which is beneficial to theranostics. However, PEG–PMPC-based polymers have rarely been used as nanocarriers in the theranostic field due to their limited modifiability and weak interaction with other materials. Herein, a plain method was propo...... hiện toàn bộ
Green synthesis of biocompatible gold nanoparticles using Fagopyrum esculentum leaf extract
Frontiers of Materials Science - Tập 5 - Trang 379-387 - 2011
Punuri Jayasekhar Babu, Pragya Sharma, Mohan Chandra Kalita, Utpal Bora
This report describes the use of ethnolic extract of Fagopyrum esculentum leaves for the synthesis of gold nanoparticles. UV-visible spectroscopy analysis indicated the successful formation of gold nanoparticles. The synthesized nanoparticles were characterized by transmission electron microscopy (TEM), high resolution TEM (HRTEM) and were found to be spherical, hexagonal and triangular in shape w...... hiện toàn bộ

Preparation of poly(N-isopropylacrylamide) brush grafted silica particles via surface-initiated atom transfer radical polymerization used for aqueous chromatography
Frontiers of Materials Science - Tập 6 - Trang 60-68 - 2012
Zong-Jian Liu, Yan-Li Liang, Fang-Fang Geng, Fang Lv, Rong-Ji Dai, Yu-Kui Zhang, Yu-Lin Deng
Thermoresponsive poly(N-isopropylacrylamide) (PNIPAAm) brushes were densely grafted onto silica surface via surface-initiated atom transfer radical polymerization (SI-ATRP). The grafting reaction started from the surfaces of 2-bromoisobutyratefunctionalized silica particles in 2-propanol aqueous solution at ambient temperature using CuCl/CuCl2/N,N,N′,N′,N″-pentamethyldiethylenetriamine (PMDETA) as...... hiện toàn bộ
Recent research situation in tin dioxide nanomaterials: synthesis, microstructures, and properties
Frontiers of Materials Science - Tập 7 - Trang 203-226 - 2013
Zhi-Wen Chen, Chan-Hung Shek, C. M. Lawrence Wu, Joseph K. L. Lai
This review article summarizes the new research in solid-state physical chemistry understanding of the microstructure characteristics of semiconductor tin oxide thin films made in the last years in our group. The work mainly focuses on the fabrication technology of semiconductor tin oxides thin films by using pulsed laser deposition (PLD) as well as the application of this technology on new micro-...... hiện toàn bộ
Electrospun polypyrrole-coated polycaprolactone nanoyarn nerve guidance conduits for nerve tissue engineering
Frontiers of Materials Science - Tập 12 - Trang 438-446 - 2018
Xin Pan, Binbin Sun, Xiumei Mo
Nerve guidance conduits (NGCs) can provide suitable microenvironment for nerve repair and promote the proliferation and migration of Schwann cells (SCs). Thus, we developed nerve guidance conduits (NGCs) with polypyrrole-coated polycaprolactone nanoyarns (PPy-PCL-NYs) as fillers in this study. PCL-NYs with the oriented structure were prepared with a double-needle electrospinning system and then PP...... hiện toàn bộ
Biomineralized and chemically synthesized magnetic nanoparticles: A contrast

Wettability manipulation of magnetic transition metal nanorod arrays by X-ray irradiation
Frontiers of Materials Science - Tập 9 - Trang 311-315 - 2015
Qian Xie, Weipeng Wang, Zheng Xie, Shuang Shuang, Zhengcao Li, Zhengjun Zhang
Wettability manipulation of glancing angle deposited Fe/Co/Ni nanorod arrays was realized by X-ray irradiation in ultra-high vacuum chamber. Reversible transition was also purchased by alternating ethanol immersion and X-ray irradiation. Alkyl group adsorption–desorption mechanism and corresponding morphology dependence of wettability manipulation were revealed.
Improvement in synthesis of (K0.5Na0.5)NbO3 powders by Ge4+ acceptor doping
Frontiers of Materials Science - - 2016
Yajing Zhao, Yan Chen, Kepi Chen
In this paper, the effects of doping with GeO2 on the synthesis temperature, phase structure and morphology of (K0.5Na0.5)NbO3 (KNN) ceramic powders were studied using XRD and SEM. The results show that KNN powders with good crystallinity and compositional homogeneity can be obtained after calcination at up to 900°C for 2 h. Introducing 0.5 mol.% GeO2 into the starting mixture improved the synthes...... hiện toàn bộ
Nanodiamonds as nanomaterial for biomedical field
Frontiers of Materials Science - Tập 15 - Trang 334-351 - 2021
Sarah Garifo, Dimitri Stanicki, Gamze Ayata, Robert N. Muller, Sophie Laurent
Recent advances in nanotechnology have attracted significant attention to nanodiamonds (NDs) in both industrial and research areas thanks to their remarkable intrinsic properties: large specific area, poor cytotoxicity, chemical resistance, magnetic and optical properties, ease of large-scale production, and surface reactivity make them suitable for numerous applications, including electronics, op...... hiện toàn bộ
