Researchers have developed nanoflower dressings that fight infections and speed up wound healing by offering innovative antibiotic and anti-inflammatory protection
Researchers are developing innovative methods with nanoflowers that have antibiotic and anti-inflammatory properties, capable of fighting infections and promoting wound healing.
Laboratory tests have shown that dressings coated with nanoflowers could be a significant advance in wound care, particularly due to their effectiveness in fighting bacteria.
The discovery was published in the magazine ACS Applied Bio Materials, in a study led by Fatemeh Ahmadpoor and Pier Francesco Ferrari.

Nanoflower technology
Nanoflowers are microscopic, self-assembling structures that have a large surface area, ideal for drug delivery.
In this study, scientists used two key substances: tannic acid and copper(II) phosphate, for their antibiotic and anti-inflammatory properties. The nanoflowers were grown in saline solution and then applied to strips of electrospun nanofiber fabric, forming dressings.
These dressings, which mimic the shape of flowers, are effective against a wide range of bacteria, including E. coli, Pseudomonas aeruginosa e Staphylococcus aureus, in addition to being able to deactivate antibiotic-resistant biofilms.
Most importantly, tests indicated that the nanoflowers did not cause harm to human cells in the laboratory.
Promising results for medicine
Nanoflower-coated dressings could revolutionize wound care. According to researchers, this approach not only offers a natural and cost-effective solution, but also shows high efficiency in fighting infections and healing wounds.
The use of these technologies could redefine current standards of wound care, as conventional solutions are often not sufficient to deal with complex infections.
In addition to laboratory tests, the study also indicates that the bioincompatibility of the dressings with human cells was practically non-existent, a crucial factor for clinical vision.
Funding for this research was provided by the Italian Ministry of University and Research, and the results make clear the potential of nanoflowers for advancing medical technologies.
