What do we need from PAT?

18 December 2017 | By ,

Pharmaceutical manufacturing in the modern era is facing unprecedented demands, including in-depth scrutiny of production methodology, and inefficiencies in current practices with respect to waste, energy usage and time management. Coupling this with increased complexity in the manufacture of newer products and the decline of blockbuster drugs, results in an…

Surface-enhanced Raman spectroscopic sensing of glucose

15 December 2017 | By ,

The small normal Raman cross-section of glucose is a major challenge in its detection by surface enhanced Raman spectroscopy (SERS) for medical applications, such as blood glucose level monitoring of diabetic patients and evaluation of patients with other medical conditions, since glucose is a marker for many human diseases. Here…

Photobleaching profile of Raman peaks and fluorescence background

15 December 2017 | By , , , ,

Laser-induced fluorescence is the most common source of interfering baseline signal encountered in Raman measurements. It shows itself as a slowly changing background in a spectrum. One of the challenges in the successful use of Raman spectroscopy is to extract Raman signatures from this, orders of magnitude stronger, broadband fluorescence…

Non-clinical dose formulation considerations

15 December 2017 | By

Designing appropriate non-clinical safety studies requires thoughtful, and sometimes experimental, consideration of the delivery methodology for the therapeutic. The choice of formulation affects drug release and absorption and has a direct impact on the pharmacokinetic profile and associated response of the model system. The formulation should be compatible with the…
