Use of confocal Raman microscopy to characterise ethyl cyanoacrylate adhesive depth curing

The use of near-infrared spectroscopy for the cure monitoring of an ethyl cyanoacrylate adhesive

Near-IR reflectance spectroscopy has been used to study the curing of ethyl cyanoacrylate adhesive on polished dental glass and microscope slide substrates. The effects of changing the glue film thickness and the type of substrate on the curing rate have been investigated whilst maintaining a constant humidity. The FTIR spectral data has been used to calculate and plot the extents of cure versu...

Ethyl 2-cyanoacrylate tissue adhesive in partial lobectomy in rats.

OBJECTIVE To determine the efficacy of ethyl 2-cyanoacrylate adhesive in repairing the lung parenchyma after partial lobectomy in rats, in terms of hemostasis/aerostasis, scarring, and surgical time. METHODS The study involved 30 Wistar rats, randomly divided into five groups (one control group and four study groups). In the study groups, the lung parenchyma was repaired with either cyanoacry...

Comparative study of the use of ethyl cyanoacrylate adhesive and intracutaneous suture for cutaneous excision closure

Background: The advantages of cyanoacrylates in cutaneous wound closure have been wi­ dely demonstrated in the literature. However, these products have not been widely used in Brazil due to the high costs of octyl cyanoacrylates. Moreover, there have been only a few studies on the most affordable product, ethyl cyanoacrylate, as a cutaneous adhesive. The objective of this study was to evaluate ...

IN-DEPTH FOCUS: RAMAN Raman hyperspectral imaging: a single tool to characterise pharmaceutical products

Hyperspectral imaging – or spectral imaging – was first used in the material, food and biological domains. But it is increasingly being employed by pharmaceutical professionals, since it combines the dual advantages of spectroscopic techniques and imaging. Hyperspectral imaging allows the user to acquire the spectrum at each pixel of a defined image. It is thus possible to visualise properties ...
