Reassembled One-Dimensional VB2 Submicrorods with Enhanced Photosensitivity and H2O2 Supply for Efficient Antibacterial Therapy

Jianxing Feng,
Xuewei Yang,
Tianyu Wang
et al.

Abstract: Recent advances in photocatalytic micro-nanoarchitecture have enlightened emerging photosensitizer-based photodynamic bactericidal therapies, which have been fruitful in addressing the thorny issue of multidrug-resistant bacterial infections. Nevertheless, the clinical feasibility of current photodynamic sterilization has been constrained by the biosafety of the photosensitizer and the maintenance of a relatively mild physiological microenvironment during treatment. Herein, we assemble a rodlike monocrystal on… Show more

“…By integrating these biologically compatible fluorophores in viruses, tissues, and cells, biological laser systems are enabled to be fabricated, capitalizing on these natural beings to serve as the biological gain medium. The preceding study centered on enhancing photosensitivity in reassembled one-dimensional VB2 submicron rods, aiming to achieve efficient antibacterial therapy (Figure 2, [58]). The biological laser [42] circumvents the biological hazards associated with traditional devices of the laser.…”

The preceding study centered on enhancing photosensitivity in reassembled one-dimensional VB2 submicron rods, aiming to achieve efficient antibacterial therapy (Figure 2, [58]). Typically comprised of three primary components-an optic cavity for light confinement, a gain medium to amplify incident light within the cavity, and a source of energy of pump-the laser system's photons undergo iterative relations with the initiated gain medium, resulting in photon amplification.…”

“…Skin is an important barrier that protects the human body from harmful microbes. , But the defense capability of the skin will decrease once wounded, which makes the fact that bacteria, including Acinetobacter , Pseudomonas , and Staphylococci , are prone to colonize around wounds, resulting in potential harm to human health. , Antibiotics are a common approach to resistance to bacterial infections; unfortunately, the treatment effectiveness has decreased over the past years due to the emergence of drug-resistant bacteria. , Therefore, hydrogen peroxide (H 2 O 2 ) and other reactive oxygen species (ROS) agents widely serve as antimicrobials to avoid the overuse of antibiotics . With the rapid development of material science and nanotechnology, a vast number of nanomaterials that can induce ROS under irradiation, ultrasound, and temperature stimulation have been constructed for antimicrobial therapy. Those treatment approaches based on ROS offer an alternative strategy for bacterial infection treatment.…”
