Upconversion Nanoparticle‐Covalent Organic Framework Core–shell Particles as Therapeutic Microrobots Trackable With Optoacoustic Imaging

open access: yesAdvanced Materials, EarlyView.
Upconversion nanoparticle‐covalent organic framework core–shell particles provide enhanced contrast for optoacoustic imaging by leveraging the optical absorption of upconversion luminescence within the covalent organic framework matrix. Beyond their role as contrast agents, these particles enable customizable therapeutic agent loading and release, as ...

Is the leaking balloon angioplasty catheter a better catheter?

open access: yesJournal of the American College of Cardiology, 1989
Because of the presence of multiple proximal and distal sideholes, the autoperfusion balloon angioplasty catheter allows passive perfusion of blood through its central lumen while the balloon is inflated. This unique property can serve two major purposes.

Virus Enhanced Microrobots for Biofilm Eradication

open access: yesAdvanced Materials, EarlyView.
Biofilms resist antimicrobials across medicine, industry, and environments. We present virus‐conjugated microrobots synthesized hydrothermally and magnetically actuated. Their motion and viral specificity enable targeted binding, penetration, and delivery, outperforming bare microrobots.

Peptide Amphiphiles Hitchhike on Endogenous Biomolecules for Enhanced Cancer Imaging and Therapy

open access: yesAdvanced Materials, EarlyView.
Weakly assembled peptide amphiphile nanostructures disassemble in circulation and reassemble with blood biomolecules, mainly lipoproteins. Binding to blood biomolecules prolongs blood circulation and improves accumulation in solid tumors. In the tumor microenvironment, peptide amphiphiles assemble with cholesterol‐rich domains of cell membranes ...
