New Antimicrobial Polymer Developed from Sulfur

Researchers at Flinders University have developed a sulfur-rich antimicrobial polymer material. The study, 'A poly(trisulfide) oligomer with antimicrobial activity,' was published in the journal Chemical Science. The research team was led by Flinders University and included experts from the United Kingdom.

Material Properties and Testing

The material is described as a sulfur-rich polymer that shows activity against a variety of fungal and bacterial pathogens.

According to the researchers, the material does not harm human or plant cells in their tests.

Work on the material has been expanded to test it against multiple pathogenic strains.

Statements from Researchers

Professor Justin Chalker stated the material has potential applications in medicine and agriculture.

Lead author Dr. Jasmine Pople stated that sulfur-based chemistry is a promising approach for developing next-generation antimicrobial agents. She noted that antimicrobial resistance, particularly in fungal pathogens, is an increasing clinical and agricultural threat.

Dr. Pople first observed the antimicrobial activity in 2024 while on an exchange at the University of Liverpool.

Co-author Associate Professor Bart Eijkelkamp stated that integrating chemical synthesis with biological evaluation strengthened the research results.

Background and Context

Elemental sulfur and other sulfur-based molecules have historically been used as antimicrobials but can be malodorous and difficult to formulate due to solubility limitations.

Professor Chalker noted that this development is part of broader efforts at Flinders University to convert sulfur into value-added materials.

This broader effort also includes projects for metal remediation and optical lenses.
