Biofilm colonies are typically resistant to general antibiotic treatment and require targeted methods for their removal. One of these includes the use nanoparticles as carriers delivery, where they randomly circulate in fluid until make contact with infected areas. However, required proximity particles biofilm results only moderate efficacy.

Micro/nanomotors are useful tools for several biomedical applications, including targeted drug delivery and minimally invasive microsurgeries. However, major challenges such as in vivo imaging need to be addressed before they can safely applied on a living body. Here, we show that positron emission tomography (PET), molecular technique widely used medical imaging, also track large population of tubular Au/PEDOT/Pt micromotors. Chemisorption an iodine isotope onto the micromotor's Au surface...

The movement multiple motors across a peroxide-activated contaminated solution enhances decontamination efficiency compared with common processes chemical warfare agents.
Water contamination is one of the most persistent problems public health. Resistance some pathogens to conventional disinfectants can require combination multiple or increased disinfectant doses, which may produce harmful byproducts. Here, we describe an efficient method for disinfecting Escherichia coli and removing bacteria from contaminated water using self-propelled Janus microbots decorated with silver nanoparticles (AgNPs). The structure a spherical microbot consists magnesium (Mg)...
Water contamination from industrial and anthropogenic activities is nowadays a major issue in many countries worldwide. To address this problem, efficient water treatment technologies are required. Recent efforts have focused on the development of self-propelled micromotors that provide enhanced micromixing mass transfer by transportation reactive species, resulting higher decontamination rates. However, real application these still limited due to high cost associated their fabrication...
