Objective:
To observe antibiotic diffusion in biofilms using surface-enhanced Raman spectroscopy (SERS) with gold nanostars.
Key Findings:
- Antibiotic diffusion rates in biofilms were over three orders of magnitude lower than in water.
- Gold nanostars provided a solution to measuring within the complex biofilm matrix.
- The method allows for quantitative analysis of antibiotic penetration and biofilm resistance.
Interpretation:
The findings indicate that biofilms significantly hinder antibiotic diffusion, contributing to antibiotic resistance, and highlight the potential of SERS for studying biofilm dynamics.
Limitations:
- The study focused on a specific antibiotic and bacterial species.
- Further validation is needed to extend findings to other biofilm types and antimicrobial agents.
Conclusion:
This research provides a new tool for understanding biofilm behavior and could inform the development of more effective antimicrobial strategies.

About the Author(s)
James Strachan
Over the course of my Biomedical Sciences degree it dawned on me that my goal of becoming a scientist didn’t quite mesh with my lack of affinity for lab work. Thinking on my decision to pursue biology rather than English at age 15 – despite an aptitude for the latter – I realized that science writing was a way to combine what I loved with what I was good at. From there I set out to gather as much freelancing experience as I could, spending 2 years developing scientific content for International Innovation, before completing an MSc in Science Communication. After gaining invaluable experience in supporting the communications efforts of CERN and IN-PART, I joined Texere – where I am focused on producing consistently engaging, cutting-edge and innovative content for our specialist audiences around the world.
