• WITec introduces Ultrafast Confocal Raman Imaging Option

  WITec introduces the "Ultrafast Raman Imaging Option" for the alpha300 R Confocal Raman Microscope. With this option the acquisition time for a single Raman spectrum can be as low as 1.7 milliseconds, according to the company. As a Confocal Raman image typically consists of tens of thousands of spec more

• Structural and Chemical 3D Imaging with AFM and Raman.
  

  In the Life Sciences and Bio-medical Research, the characterization of chemical compounds within cells or tissues is one of the most important and difficult tasks for researchers to perform. The development of pharmaceuticals such as drug delivery coatings or capsules also requires as much information as possible about their chemical and structural compositions. For the fields of nanotechnology and materials science, a thorough knowledge of the samples' surface morphology on a sub-micron scale is essential more

• Application of melt granulation technology using twin‐screw extruder in development of high‐dose modified‐release tablet formulation

  Abstract Development of modified‐release oral tablets of drug products usually requires release‐modifying polymers at the level of above 50% of the total weight. This makes the development of high‐dose products, especially with doses in the range of 750–1000 mg, difficult because the tablet size more

• Surface Engineered Poly(lactide-co-glycolide) Nanoparticles for Intracellular Delivery: Uptake and Cytotoxicity—A Confocal Raman Microscopic Study

  Confocal Raman Microscopy (CRM) is used to study the cell internalization of poly(lactide-co-glycolide) (PLGA) nanoparticles (NPs) fabricated by emulsion techniques with either poly(ethylene imine) (PEI) or bovine serum albumin (BSA) as surface stabilizers. HepG2 cells were exposed to PEI and BSA st more
