Nanoparticles

Nowadays, solvent-free, one-part cyanoacrylate adhesive is widely used in medicine and dentistry. According to a literature survey done by the authors, there are few papers concentrated on the role of nano-sized particles on the thermal behavior of cyanoacrylate glue. Thus the main goal of the current research focused on clarifying the role of nano-sized SiO2 on the thermal behavior of cyanoacrylate. Thermal behavior of all materials including cyanoacrylate and its nanocomposites was studied by using Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) methods.

Non-invasive surgery techniques and drug delivery system with acoustic characteristics of ultrasound contrast agent have been studied intensively in recent years. Many ultrasound contrast agents are commercially available, and they are usually composed of a microbubble coated by a surfactant or lipid bilayer, i.e., a hollow microsphere. We show that the hollow microsphere with polymer shell can be fabricated just blowing vapor of commonly-used instant adhesive into water as microbubbles.

A general methodology was proposed to prepare highly functionalized poly(alkyl cyanoacrylate) nanoparticles by means of Huisgen 1,3-dipolar cyclo-addition, the so-called click chemistry.
