Time : 12:15-12:55
Biography:
Marc Plante has been working in the field of analytical chemistry and chromatography for over 25 years, complete with a variety of publications, speeches, webinars and a wide range of experience. He first earned his BSc in Chemistry with two minors in engineering at Rensselaer Polytechnic Institute in Troy, New York and then a doctorate in Physical-Organic chemistry at Northeastern University. His first employment involved a novel semi-synthetic taxane process, for which he helped developed a now-patented chromatographic purification system. Over the course of his current career, he has largely worked with small-molecule chromatography, with much of his work involving the Corona Charged Aerosol Detector. At ESA, Dionex and Thermo Fisher Scientific, he created application notes and posters, gave many presentations and wrote two book chapters. He also provided some ideas for improving the detector's capabilities.

Abstract:
While there has been a growing interest in understanding the pharmacological and physiological properties of cannabinoids in the last decades, analytical methodologies including sample preparations, remain one of the most challenging topics for their quantification in biological matrices. Moreover, the low sample weight or volume coupled to the complexity of biological samples (i.e. whole blood, plasma, etc.) could overwhelm the analyst expectations. In this study, we explored different possibilities to quantify a mixture of 8 natural phytocannabinoids present in biological samples (cannabinol, cannabigerolic acid, cannabinochromene, cannabigerol, cannbidiolic acid, tetrahydrocanninol, tetratracannabinolic acid and cannabidiol). The evaluation was carried-out using plasma and whole blood samples using different usual extraction protocols (solid phase extraction, liquid-liquid extraction, protein precipitation and blood spot sampling). Stability of tested molecules was also evaluated in several matrices (plasma, serum, ex vivo and pharmacokinetic profiles). The results showed a moderate matrix effect resulting by signal suppression (≤30%) and acceptable recoveries (≥60%) for most of the different tested extractions and matrices, except for whole blood when using acetonitrile for protein precipitation, which appears to be the less efficient approach for cannabinoid extraction, with a recovery lower than ≤40%. The applicability of tested methodologies was also applied for the determination of pharmacokinetic profiles and showed that dried blood spot sampling (DBS) could become an interesting alternative for in vivo studies. DBS is a rapid, acute and minimally invasive technic based on a single blood drop (10µL–25µL) that reduces handling and quantity of blood to be sampled, which consequently also reduces the cost of analysis. According to these aspects, DBS could become a reference methodology for in vivo pharmacokinetic experiments.

Abstract:
Optical spectroscopy remains a widely used and most important tool for investigating and characterizing the properties of matter. The energy used in optical spectroscopy exists in the form of optical photons or quanta, with a wavelength ranging from less than 1AËš in the x-ray region to more than 10 6AËš in the far-infrared. It is highly versatile, widely ranged and nondestructive in nature. Optical Spectroscopy has been a scientific tool for over a century and a half and it has proven invaluable in studies on reasonably clear media, such as solutions and crystals and on specularly reflective surfaces. There are, however, several instances where conventional transmission spectroscopy is inadequate even for the case of clear, transparent materials. Such a situation arises when one is attempting to measure a very weak absorption, which in turn involves the measurement of a very small change in the intensity of a strong, essentially unattenuated, transmitted signal. Although this problem occurs for all forms of matters, it has received particular attention in the case of transparent gas mixtures containing minute quantities of an absorbing species or pollutant. Various techniques develop to overcome this difficulty, such as derivative spectroscopic, have proven to generally inadequate. In addition to weakly absorbing materials, there are a great many nongaseous substances, both organic and inorganic, that are not readily amenable to the conventional transmission or reflection modes of optical spectroscopy. These are usually highly light-scattering materials, such as powders, amorphous solids, gels, smears and suspensions. Other difficult materials are those that are optically opaque and have dimensions that far exceed the penetration depth of the photons. Over the years, several techniques have been developed to permit optical investigation of highly light – scattering and opaque substances. The most common of these are diffuse reflectance, attenuated total reflection (ATR) and internal reflection spectroscopy and Raman scattering. All these techniques have proven to be very useful, yet each suffers from serious limitations. In particular, each method is applicable to only a relatively small category of materials, each is useful over a small wavelength range and the data obtained are often difficult to interpret. The modern scanning and tunneling microscopic techniques in spite of their versatility are having inherent inadequacies and economically very costly. The photoacoustic spectroscopy strikes a balance between the optical spectroscopy and the modern microscopic techniques in that it is relatively cheaper, highly efficient over a wide range of wavelengths, applicable for any type of material. The newly developed electronics technology is highly assisting the versatility of the photoacoustic spectroscopy (PAS), Ultrasonic photoacoustic microscopy and Piezoelectric Photoacoustic microscopy (PPAM) to study the thermal and optical characteristics of any type of materials in the micro and nanoscales. In this work, we present the thermal diffusivity measurement of Poly (methyl methacrylate) (PMMA) - montmorillonite (MMT) clay nanocomposite by PPAM and compare it with the X-ray diffraction studies.
