Maria Crisler’s Raman Microscope Fundraiser

Maria Crisler and Guardians of Human Health are raising funds for a Raman system to support independent research. The published equipment campaign describes a US$306,000 system, including analytical applications and chemical-reference libraries. Maria is listed as a co-organiser, and Guardians of Human Health is the beneficiary.

Why Raman microscopy?

A conventional optical microscope shows what a sample looks like. Raman analysis adds information about its chemical structure. A laser illuminates the sample, and the resulting spectrum can be compared with reference measurements to help identify materials.

Adding this capability could help Maria investigate the composition of suitable samples alongside their appearance. It is a way to ask more precise research questions and test material identifications.

What can it help researchers study?

• Polymers: distinguish suitable plastic and polymer materials using their chemical signatures, including analysis of individual particles.
• Graphene and other carbon materials: characterise carbon structures and investigate features such as defects and the number of graphene layers.
• Food composition: investigate ingredients, impurities and some forms of adulteration using methods developed for the particular sample.

These are established applications of Raman analysis, described by instrument manufacturers HORIBA and Renishaw.
