Real-time monitoring of hemodynamics is crucial for diagnosing disorders within implanted vascular grafts and facilitating timely treatment. Integrating vascular grafts with advanced flexible electronics offers a promising approach to developing smart vascular grafts (SVGs) capable of continuous hemodynamic monitoring. However, most existing SVG devices encounter significant challenges in practical applications, particularly regarding biomechanical compatibility and the effective evaluation of vascular status.

Glioblastoma multiforme (GBM) is a highly invasive and fatal brain tumor with a grim prognosis, where current treatment modalities, including postoperative radiotherapy and temozolomide chemotherapy, yield a median survival of only 15 months. The challenges of tumor heterogeneity, drug resistance, and the blood-brain barrier necessitate innovative therapeutic approaches. This study introduces a strategy employing biomimetic magnetic nanorobots encapsulated with hybrid membranes derived from platelets and M1 macrophages to enhance blood-brain barrier penetration and target GBM.

Porous silicon (pSi) has gained substantial attention as a versatile material for various biomedical applications due to its unique structural and functional properties. Initially used as a semiconductor material, pSi has transitioned into a bioactive platform, enabling its use in drug delivery systems, biosensing, tissue engineering scaffolds, and implantable devices. This review explores recent advancements in macrostructural pSi, emphasizing its biocompatibility, biodegradability, high surface area, and tunable properties.

Osteoporosis is a systemic metabolic disease that impairs bone remodeling by favoring osteoclastic resorption over osteoblastic formation. Nanotechnology-based therapeutic strategies focus on the delivery of drug molecules to either decrease bone resorption or increase bone formation rather than regulating the entire bone remodeling process, and osteoporosis interventions suffer from this limitation. Here, we present a multifunctional nanoparticle based on metal-phenolic networks (MPNs) for the treatment of systemic osteoporosis by regulating both osteoclasts and osteoblasts.

Ferroptosis combined with photodynamic therapy (PDT) has emerged as a powerful approach to induce cancer cell death by producing and accumulating lethal reactive oxygen species (ROS) in the tumor microenvironment (TME). Despite its efficacy and safety, challenges persist in delivering multiple drugs to the tumor site for enhanced antitumor efficacy and improved tissue targeting. Hence, we designed a method of inducing ferroptosis through laser-mediated and human homologation-specific efficient activation, which is also a ferroptosis therapy with higher safety through ROS-mediated.
