Fabrication of hollow silver spheres by MPTMS-functionalized hollow silica spheres as templates

Novel One-pot Fabrication of Lab-on-a-Bubble@Ag Substrate without Coupling-agent for Surface Enhanced Raman Scattering

“…LoBs@APTES@Ag substrates are indifferent of Brownian movement, and serve as a convenient platform to directly detect the target molecules in solution, without draining water. Aminopropyltrimethoxisilane (APTMS), mercaptopropyltrimethoxysilane (MPTMS), dopamine (DA) and polydopamine (PDA) were also used as coupling agents for surface modification 20 21 . The use of a coupling agent strengthens the interfacial adhesion of NPs on SiO 2 microspheres, but the silylation process is time-consuming.…”

Template-free synthesis of Cd(OH)2 hollow spheres and its optical properties

“…Li et al synthesized hollow titania spheres with controllable shells using polystyrene particles as a template in conjunction with the sol-gel method [9]. Park et al fabricated hollow silver spheres with MPTMSfunctionalized hollow silica spheres as templates [10]. Most of the reported hollow spheres are generally fabricated by templateassisted method [9,10] or by Win/O/Wout method [11], which makes the experiments more complicated.…”

Moreover, an important challenge is how to retain the shell structures during core removal.…”

Synthesis and Surface Properties of Silica Spheres with Core Shell Structure by One Convenient Method

“…Silica spheres have almost been obtained by using a biphasic system of a quaternary ammonium surfactant [5][6][7], that recently has been synthesized using the nonionic polyethylene-oxide-based surfactant by Boissiére et al [8] and dual templates by Yang et al [9]. Silica spheres of hollow morphologies have attracted much attention due to their potential applications in drug-delivery, adsorption, and catalysis [10]. Hollow spheres may also provide some immediate advantages over their solid counter parts because of their relatively low densities [11].…”
