WebJul 18, 2024 · Cyanoacrylate, also called super glue, fuming is a chemical method for the detection of latent fingermarks on non-porous surfaces such as glass, plastic etc. The method relies on the deposition of polymerized cyanoacrylate ester on residues of latent fingermarks. The method develops clear, stable, white colored fingerprints. However, … WebCyanoacrylate adhesives are cyanoacrylate esters, of which methyl and ethyl cyanoacrylates are the most commonly used in adhesive formulation (Figure 1). Cyanoacrylates undergo anionic polymerization in the presence of a weak base such as water, and are stabilized through the addition of a weak acid.
WebEndovascular embolization agents are particles and fluids that can be released into the bloodstream through a catheter to mechanically and/or biologically occlude a target vessel, either temporarily or permanently. Vascular embolization agents are available as solids, liquids, and suspensions.
