Photonic crystal formation on optical nanofibers using femtosecond laser ablation technique

, 2012
We demonstrate that thousands of periodic nano-craters are fabricated on a subwavelength-diameter tapered optical fiber, an optical nanofiber, by irradiating with just a single femtosecond laser pulse.

DNA‐Origami‐Assembled Rhodium Nanoantennas for Deep‐UV Label‐Free Single‐Protein Detection

Advanced Functional Materials, EarlyView.
Deep‐UV autofluorescence of single proteins in DNA origami‐based rhodium nanoantennas. Precisely positioned within the plasmonic nanogap, proteins retain their native state while their intrinsic emission is strongly amplified, enabling label‐free single‐molecule detection and opening new opportunities for highly sensitive and specific biosensing ...

Design and Synthesis of Peptide‐Polyester Conjugates for Cell‐Mediated Scaffold Degradation

Advanced Healthcare Materials, EarlyView.
This work describes polycaprolactone (PCL)‐based biomaterials engineered to degrade in response to cell‐secreted proteases. A fast‐degrading peptide (Fast) sequence is integrated into a PCL conjugate backbone to produce a biomaterial that is selectively degraded by multiple cell types compared to its scrambled control (ScrFast).
