An age-old household staple could play a role in tackling one of modern medicine’s growing challenges, with new research suggesting vinegar may be far more powerful when paired with cutting-edge technology.
Chronic wounds those that fail to heal pose a serious risk, particularly for elderly patients and those living with conditions such as diabetes or cancer. These wounds are often complicated by stubborn bacterial infections, some of which are resistant to antibiotics.
Now, scientists from QIMR Berghofer Medical Research Institute, Flinders University and the University of Bergen have turned to a familiar “home remedy” vinegar to explore new treatment options.
Vinegar, or acetic acid, has long been used as a disinfectant, but its effectiveness has traditionally been limited to a narrow range of bacteria. However, the latest study has found that adding microscopic antimicrobial particles can significantly boost its bacteria-fighting power.
The research, published in the international journal ACS Nano, focused on combining weak vinegar with nanoparticles made from carbon and cobalt.
Molecular biologist Dr Adam Truskewycz said the acidic nature of vinegar plays a key role in the treatment’s effectiveness.
“The vinegar creates an environment where bacterial cells swell, allowing them to take up the nanoparticles more easily,” he said.
“Once inside, the particles attack the bacteria from within and on the surface, ultimately causing them to burst.”
The study found the enhanced vinegar solution was effective against several dangerous pathogens, including drug-resistant strains such as Staphylococcus aureus infection, Escherichia coli infection and Enterococcus faecalis infection.
Importantly, researchers said the treatment did not harm human cells and successfully cleared infections in wound models without slowing the healing process.
Co-researcher Professor Nils Halberg said the findings highlight how traditional remedies can be reimagined using modern science.
“Combination treatments like this could play an important role in addressing antimicrobial resistance,” he said.
Antimicrobial resistance where bacteria evolve to survive current treatments is a growing global concern, with millions of deaths each year linked to drug-resistant infections.
Researchers hope the discovery could lead to new, more effective treatments for chronic wounds, offering a simple yet innovative approach to a complex and escalating health issue.
