H2O2‐Generating Advanced Nanomaterials for Cancer Treatment
Advanced Functional Materials, EarlyView.H2O2‐generating nanoplatforms can exploit tumor redox imbalance for O2 and toxic reactive oxygen species generation, leading to hypoxia reversal, and apoptosis of cancer cells, respectively. This review highlights the mechanisms of these nanoplatforms, including exogenous H₂O₂ delivery, endogenous amplification, and metal peroxides, which leads to ...

Underwater Optical Image Processing: A Comprehensive Review [PDF]
arXiv, 2017 Underwater cameras are widely used to observe the sea floor. They are usually included in autonomous underwater vehicles, unmanned underwater vehicles, and in situ ocean sensor networks. Despite being an important sensor for monitoring underwater scenes, there exist many issues with recent underwater camera sensors.

Advanced Healthcare Materials, EarlyView.This study investigates hTert‐immortalized human nucleus pulposus (iHNPCs) and annulus fibrosus (iHAFCs) cells for intervertebral disc (IVD) regeneration and spinal fusion models. A 3D‐printed citrate‐based scaffold loaded with BMP9‐stimulated iHAFCs and BMP2‐stimulated iHNPCs effectively promotes bone and cartilage formation, mimicking the IVD ...

A Multi-Modal Approach Based on Large Vision Model for Close-Range Underwater Target Localization [PDF]
IEEE/ASME Transactions on Mechatronics, 2024Underwater target localization uses real-time sensory measurements to estimate the position of underwater objects of interest, providing critical feedback information for underwater robots. While acoustic sensing is the most acknowledged method in underwater robots and possibly the only effective approach for long-range underwater target localization ...

Advanced Healthcare Materials, EarlyView.Segmented PCL‐bisurea (BU) polymers and BU‐peptide conjugate additives assemble into fibrous superstructures at the nanoscale through a mix‐and‐matching strategy. Different bioactivities are incorporated through variation of peptide sequences. The resulting materials are screened for their effect on stem cell adhesion and pluripotency.
