Reagents for infrared chemical imaging of fingerprints on difficult surfaces
… involves fuming samples with monomeric ethyl 2-cyanoacrylate (superglue). This reagent leaves a white residue (polymeric cyanoacrylate) on the ridges of latent fingerprints, rendering them visible under white light. On some surfaces, such as polymer banknotes, however, the contrast between …

Latent Fingerprint Enhancement on a Brass Metal Surface using Paint Electrodeposition
… plays a key role in apprehending a suspect. Cyanoacrylate fuming is one the most successful methods of enhancing fingerprints from metallic surfaces. Despite the success of cyanoacrylate fuming, fingerprint recovery on fired cartridge casings is rarely successful. Therefore, a new fingerprint …

An investigation of some chromatographic and electrophoretic seperations for industrial and clinical applications
… that may be present at different stages of the cyanoacrylate adhesive production process. A highly efficient CE separation was developed and applied to the simultaneous determination of inorganic and acidic anions, which are present in ethyl cyanoacrylate adhesive samples. The CE method …

The Development of Facial Prosthetics and Adhesives in Plastic and Reconstructive Surgery. A study in the application of prosthetic materials and devices used in plastic and reconstructive surgery together with tissue adhesives as an alternative to conventional ligation.
… available for retaining the facial prosetheses. Cyanoacrylate adhesives for use on skin surfaces and as tissue adhesives have been studied in detail. A novel n-butyl 413 cyanoacrylate has been developed with a viscosity, haemostatic property and stability to make it particularly suitable for use …

Analysis and characterisation of an acylphosphine oxide photoinitiator
… different solvents, such as acetonitrile and a cyanoacrylate ester, was studied and the effect of storage of BAPO in light and dark conditions was evaluated. The effects of stabilisers (ferrocene, cumene hydroperoxide (CHP) and hydroquinone (HQ)), acids (methyl sulphonic acid (MSA) and boron …

Synthesis and Development of Novel Cyclobutane Mechanophores
… mechanophore was shown to form reactive cyanoacrylate-terminated polymers due to mechanically induced retro [2+2] cyclization of the cyclobutane when exposed to external stress. These reactively-terminated polymers have potential applications in self-healing.
