TERS on Functionalized Gold Nanostructures for Nano-scale Biosensing

Surface-enhanced Raman scattering (SERS) is a powerful plasmonics-based analytical technique for biosensing. SERS effect relies on nanostructures that need to be designed to maximize enhancement factors and molecular specificity. In addition to numerical modeling, an analytical tool capable of imaging localized enhancement would be an added value.

Raman spectra of DayQuil™ and NyQuil™ collected with an immersion probe fiber-coupled to the MacroRAM™ Raman spectrometer, and a picture of the immersion probe setup.

Raman spectroscopy is well known as a powerful analytical method for qualitative chemical analysis. Less well known is that under certain conditions Raman spectroscopy can also be an effective method for quantitative analysis. Here we demonstrate that capability for quantitative analysis under a variety of conditions, involving different solutes in a solution and solution mixtures, and its applications to pharmaceutical analysis such as content uniformity.

Monitoring Biotinylated Adeno-Associated Virus (AAV) using A-TEEM

Adeno-Associated Viruses (AAVs) are becoming widely used as viral vectors to deliver cell and gene therapies and vaccines. As production methods scale to meet growing demand, more information is needed more quickly.

Polymorphisms characterization: when Raman microscopy supports the pharmaceutical industry

Polymorphisms characterization of active molecules is one piece of important information for the pharmaceutical industry, not only on raw powders, but also in the final form. Raman microscopy remains the most appropriate solution for this application. In this paper, we present an example of polymorphisms characterization by Raman microscopy using the super low frequency module.

Application note: Morphological and chemical characterization of pharmaceutical formulations

In order to control formulations of pharmaceutical products, characterizing their active compounds is critical, especially in terms of morphological and chemical characterization of particles. In this application note, two formulations from a generic and an innovator nasal spray have been analyzed to compare their compounds size and shape, and chemically characterized to compare the two formulations based on the ParticleFinderTM app for LabSpec 6. A focus is done on the active compound.

Resulting from the combination of Raman spectroscopy and optical microscopy, Raman hyperspectral imaging has proven to be an indispensable tool in the pharmaceutical field. This article will broach a number of Raman hyperspectral imaging applications that were developed in our laboratory, in order to demonstrate the significance of the technique.

The use of low molecular weight molecules in the industries of drug discovery and agri-food has become increasingly important over the course of a century of drug research and science development in agriculture and in pharmaceutical field.

Raman Microscopy in Pharmaceutical Salt Analysis

Pharmaceutical and crystallographic samples typically require detailed characterization and analysis to optimize a samples stability, physical properties and indeed general efficacy where an active drug substance is involved.

Liposomes are bilayer vesicles made of phospholipids derived from natural or man-made materials. They are mainly used in the pharmaceutical field for treatment of cancers as carriers of chemotherapeutic drugs to the tumor area.

This technical note describes kinetic fluorescence as an analytical technique to quantify non-fluorescent species. The technique is applied to the determination of thiamine (vitamin B1) in solution.

Resulting from the combination of Raman spectroscopy and optical microscopy, Raman hyperspectral imaging has proven to be an indispensable tool in the pharmaceutical field, especially to study the distribution of active(s) and excipients in a pharmaceutical drug product.

The A-TEEM Compliance Package is now available from HORIBA and enables A-TEEM to be used in a GMP environment. Discussion points will be around both the pharmaceutical applications of A-TEEM and the details of the compliance package for GMP labs.

Join Dr. Kevin Dahl of Particlese LLC and Dr. Linda Kidder of HORIBA Scientific provide tips and alternative solutions for better vaccine development and quality. They will discuss the application of multi-laser nanoparticle analysis (NTA) in determining vaccine degradation and total particle count. They will also present a new analytical approach, fluorescence A-TEEM method for rapid screening of similar but different vaccine final formulations.

The large variety of fluorescent probes, such as organic dyes, biological biotags and fluorescent nanostructures, are intensively studied due to their inherent suitability for a wide range of life science applications. Thanks to the complementary nature of its analytical solutions, HORIBA's unique offer covers fluorescence, particle analysis, AFM, Raman and XRF characterization techniques, helping to gain valuable insight into optical properties, size, morphology and composition of your bioprobes.
