  • Plasma Treated PET Films Grafted in Boronic Acid and Surface Properties

    76537137n?file=thumbnail
    Description:
    Biofilm growth on medical equipment and bacterial infections following operations have previously been treated with antibiotics. Although that method has helped kill the majority of the bacteria, it leaves a strain of stronger, antibiotic-resistant ones that have adapted to survive and reproduce. Boronic acid contains a plethora of properties, such as determining the presence of glucose, detecting cancer in an early phase, and measuring dopamine levels more accurately in the brain. This research aims to explore another potential application of boronic acid because of its promising uses. Boronic acid is incorporated after the activation of surfaces with cool plasma. Plasma-activated surfaces polymerized in boronic acid can be applied to the biomedical and biotechnological domains as an antibacterial method to replace antibiotics on medical materials effectively. This will vastly improve the quality of medical equipment and sterilization within the medical and surgical fields.

  • Inhibitory Effects of Probiotics on the Growth of Biofilms: A Review

    Tq57nr03d?file=thumbnail
    Description:
    This review examines the role probiotics can play in reducing and inhibiting the growth of biofilms that cause bacterial infections in humans. The use of probiotics as an inhibitory agent against biofilms is a new field of study that requires further research. As of now, there is little research or scientific literature to defend the health claims of several commercially sold probiotics. Also, biofilms are a fairly new field of study even though biofilms are the cause of most bacterial infections. Since biofilms have an increased antibiotic resistance, it has become increasingly more important to find alternative treatments for bacterial infections. However, there have been a couple of studies that have shown positive results for probiotics inhibiting the growth of different types of biofilms such as Lactobacillus acidophilus in patients with dental caries caused by the biofilm formation of Streptococcus mutans. Specifically, the biosurfactant of the probiotic was used to disrupt the biofilm. Another study was done on patients with Clostridium difficile infection who showed a decline in symptoms when treated with the probiotic yeast Saccharomyces boulardii as an additive to antibiotic treatments . While the oral health and gut health fields have started to utilize the benefits of probiotics, the effect of probiotics on the biofilms that cause infections for patients with medical devices has yet to be studied.
