Antibacterial Micro/Nanorobots: Innovations, Challenges, and Future Perspectives in Combatting Infection

open access: yesNano Select, EarlyView.
Antibacterial micro/nanorobots (MNRs) represent a breakthrough in antibacterial therapy, making precise delivery of drugs to the infection site. This review systematically summarizes the material composition, actuation, and applications of MNRs in combating biofilms and drug‐resistant infections while emphasizing the existing challenges of ...

Anisotropy Analysis of Bamboo and Tooth Using 4‐Angle Polarization Micro‐Spectroscopy

open access: yesNano Select, EarlyView.
Super‐resolution via orientation: spatial distribution of specific molecular vibrations are revealed at 1/20 of the diffraction limit. ABSTRACT To investigate the anisotropic properties of biomaterials, two distinct classes are considered as follows: polymer‐based (cellulose in plants) and crystalline‐based (enamel in teeth), each demonstrating ...

Impact of Al3+ Concentration on Montmorillonite Sedimentation: Insights Into Particle Size Behavior

open access: yesChemistryOpen, EarlyView.
The current research essentially focuses on the coagulation and sedimentation characteristics of particles with two distinct particle‐size compositions. The DLVO theory confirms that under the influence of aluminum ions, the coarse and fine particle sampleS of montmorillonite essentially possess the effect of eliminating or weakening the “barrier ...

Low‐Velocity Impact Response of Nacre‐Inspired E‐Glass/Epoxy Composites With Varying Platelet Sizes

open access: yesPolymer Composites, EarlyView.
Impact response of nacre‐inspired E‐glass/epoxy composites with different platelet sizes. ABSTRACT This study explores the low‐velocity impact behavior of nacre‐inspired biomimetic platelet composites (NIBPC), using low‐cost E‐glass fiber in chopped strand mat (CSM) form as reinforcement and epoxy resin as the matrix.

Adhesion Forces of Dextran on Dental Enamel as a Function of Contact Time and pH Value

open access: yesphysica status solidi (a), EarlyView.
Dextran exhibits sawtooth‐shaped retraction curves on dental enamel, indicating multiple interaction points. Adhesion forces increase with contact time (0.35 nN at 10 s to >1.5 nN at 120 s) and are independent of pH (pH 4.5–13). Comparisons with other surfaces show that adhesion on enamel is lower but statistically insignificant at the 0.05 level ...
