Acute kidney injury (AKI) and chronic kidney disease (CKD) represent the two primary forms of renal disease, both associated with high morbidity, mortality, and clinical complexity. Current diagnostic criteria lack sufficient sensitivity and specificity, driving the search for biomarkers and rapid detection methods to enhance diagnostic precision. Electrochemical, plasmonic, nanoparticle-based, and molecular probe biosensors have emerged as promising platforms for point-of-care (POC) devices, leveraging advanced surface chemistry. These technologies play a crucial role in identifying and quantifying emerging AKI and CKD biomarkers, enabling timely interventions to mitigate renal impairment. This review comprehensively explores recent advances in biosensor design, fabrication methodologies, and strategies to optimize efficacy for diverse applications. We focus specifically on electrochemical, optical, and piezoelectric transduction principles due to their distinct advantages.

This study aimed to investigate the basic properties of hydroxyapatite (HA)/β-tricalcium phosphate (β-TCP) scaffold material with poly(vinyl alcohol) (PVA) as a binder. The interfacial binding energies, bonding behaviors, and mechanical characteristics of the materials were investigated by molecular dynamics simulation (MD), and it was found that the types of functional groups and the molar occupancy of elements affected the interfacial binding behaviors of the materials. Moreover, the properties of the slurry and structural characteristics of the scaffolds at different HA/β-TCP component ratios were analyzed. The variation in the shear-thinning capacity of the slurry was explained by investigating the zeta potential, solid content, and interfacial binding energy of the materials. The basic properties of the material were not the only factors determining the mechanical properties of scaffolds; the pore and bonding characteristics, and the interfacial binding energy of the material together determine the mechanical properties of scaffolds. These analyses elucidated the impact of the component ratio on the scaffolds from both microscopic and macroscopic perspectives. Finally, the biological characterization study of the material was verified by in vitro simulation experiments, and it was found that scaffolds containing β-TCP demonstrated relatively better performance in supporting bone tissue formation compared with β-TCP-free controls.

Consequently, the development of efficient bone regeneration materials is of great clinical importance. The present study investigated a three-dimensional microporous demineralized bone matrix (DBM) combined with bone marrow mesenchymal stem cells (BMSCs) to enhance the outcomes of bone defect repair. The DBM has been developed to enhance the collagen preparation process, with the aim of retaining the collagen fiber network of the natural bone matrix and forming a three-dimensional microporous structure with good mechanical property. In vitro experiments demonstrated that the biocompatibility of DBM was superior to that of traditional cancellous and cortical bone materials, and they promoted cell adhesion, proliferation, and osteogenic differentiation as well as osteogenesis-related genes. In vivo experimentation was conducted to verify the efficacy of the treatment on a critical-sized cranial bone defect in nude mice. Micro-CT and histological analysis showed more formation of bone at 4 weeks and 8 weeks postsurgery. The DBM with optimized pore structure, degradation rate, and bioactivity enhanced the efficiency of bone defect repair by synergizing the osteogenic activity of BMSCs. The DBM with a porous and cross-linked structure could provide BMSCs with more internal surface area for attachment space to promote cell adhesion and growth and create advantages for the bone formation. Moreover, the DBM contains multifarious osteoinductive growth factors such as transforming growth factor-β (TGF-β), fibroblast growth factors (FGFs), bone morphogenetic proteins (BMPs) and insulin growth factors (IGFs), which can enhance osteogenic differentiation of BMSCs.

To address this limitation, we designed a negatively charged boronic acid-conjugated naphthalimide-appended peptide (PNGB) that spontaneously forms a fluorescent nanoassembly in aqueous medium, emitting greenish-yellow fluorescence. The PNGB nanoassembly exhibits a uniform spherical morphology with an average diameter of 13.5 nm. Remarkably, it enters KB cells (human oral epidermal cancer cells) via a nonendocytic pathway and rapidly localizes within mitochondria, achieving strong colocalization (PCC = 0.90 ± 0.03) within just 5 min of incubation. In addition to its mitochondrial targeting capability, the PNGB nanoassembly displays potent antibacterial activity, with low minimum inhibitory concentrations (MICs) of 24 and 36 μg/mL against Gram-positive <i>Staphylococcus aureus</i> (<i>S. aureus</i>) and Gram-negative <i>Escherichia coli</i> (<i>E. coli</i>) bacteria, respectively.

Compared to traditional, indirect PDT, which exploits the reaction of oxygen with the photosensitizer (PS) to damage specially targeted cells, direct PDT utilizes the PS itself to disrupt the target cell, meaning no reactive oxygen species (ROS) are generated. The activation of Type IV technologies specifically induces a structural change within the photosensitizer, resulting in the activation of its therapeutic effect. In contrast to traditional invasive surgeries, chemotherapy, or ROS-based methods, direct methods of PDT pose significantly less damaging off-target effects. Here, we propose an exciting extension of our prior reported, near-infrared light-activated, molecular nanomachines (MNMs), previously shown to promote cell-specific necrosis via disruption of cellular membranes. We show that the modification of MNMs with polyethylene glycol (PEG), or triphenol phosphonium (TPP+) containing functional groups, allows for homeostatic crossing of the phospholipid bilayer and localization at the mitochondrial membrane. By subsequent activation of the rotor from within the targeted cells, we present the ability to eliminate cells without triggering necrotic cell death, instead inducing an additional mechanism of programmed cell death (PCD), while maintaining the integrity of the cellular membrane, thus enacting a significantly cleaner, more therapeutically favorable mode of inducing cell death. A significant development is in the use of light-activated molecular machines for cancer treatments, with a single MNM-based technology being able to access both necrotic and non-necrotic modes of cell elimination by simply switching the excitation procedure.</p>","PeriodicalId":2,"journal":{"name":"ACS Applied Bio Materials","volume":" ","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145278466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
