Reconfigurable Magnetic Soft Microrobot for Acoustically Triggered Targeted Bacterial Sterilization

Advanced Functional Materials, EarlyView.
Reconfigurable magnetic soft microrobots integrate in situ‐grown piezoelectric zinc oxide nanorods that produce reactive oxygen species upon acoustic excitation. Combining magnetically guided transport with thermally induced planar reconfiguration, the microrobots achieve targeted delivery and enhanced bacterial sterilization through efficient on ...

Visible light enhances the antimicrobial effect of some essential oils [PDF]

, 2017
The photodisinfection is a topical, broad spectrum antimicrobial technology, targeting bacteria, virus, fungi, and protozoa effective for single cells as for biofilms. Natural molecules have been studied less than synthetic agents in the process but they

Impact of PVC microplastics in photodynamic inactivation of Staphylococcus aureus and MRSA

Water Science and Technology
Photodynamic processes have found widespread application in therapies. These processes involve photosensitizers (PSs) that, when excited by specific light wavelengths and in the presence of molecular oxygen, generate reactive oxygen species (ROS), that ...

Nano‐ and Micro‐Sized Solid Materials Used as Antiviral Agents

Advanced Functional Materials, EarlyView.
Due to the rise of viral infections in humans and possible viral outbreaks, the use of nano‐ or micro‐sized materials as antiviral agents is rapidly increasing. This review explores their antiviral properties against RNA and DNA viruses, either as a prevention or a treatment tool, by delving into their mechanisms of action and how to properly assess ...

The effects of photodynamic treatment with new methylene blue N on the Candida albicans proteome. [PDF]

, 2016
Candida albicans is a human pathogenic fungus mainly affecting immunocompromised patients. Resistance to the commonly used fungicides can lead to poor treatment of mucosal infections which, in turn, can result in life-threatening systemic candidiasis. In

Nanotechnology in antimicrobial photodynamic inactivation

Journal of Food and Drug Analysis, 2020
Photodynamic therapy (PDT) and photodynamic inactivation (PDI) are technologies that utilize visible light and photosensitizers (PS) to in activate cells. PDT is currently in use for the treatment of several types of tumors. Although cancer has been successfully treated with PS and light, antimicrobial PDI is emerging as a new treatment modality for ...
