Clinical therapy for periodontitis relies on mechanical debridement and adjunctive antibiotics, strategies that often result in incomplete efficacy and a high recurrence rate. The development of cerium oxide nanoparticles (nanoceria), which exhibits enzyme-like catalytic activity and biocompatibility, enables targeted redox modulation to restore ROS balance, showing promise for clinical treatment.

Ultrasound-mediated drug delivery has emerged as a revolutionary non-invasive technology for transient and targeted BBB opening, enabling enhanced penetration of therapeutic agents into the central nervous system. This review comprehensively summarizes the mechanisms underlying ultrasound-based delivery with focus on current delivery platforms including microbubble (MB)-assisted, nanoparticle-based, and MB-nanoparticle composite strategies. Furthermore, we highlight recent advances in the application of focused ultrasound (FUS) combined with MBs for the treatment of Alzheimer's disease, Parkinson's disease, and glioma. Finally, we discuss emerging technologies such as sonodynamic therapy and ultrasound-controlled magnetic nanorobots, while also addressing current challenges in this field.

Initially, BA (1–20 μM) was tested for cytocompatibility, <em>in vitro</em> mineralized nodule formation as an early indicator of odontogenic potential, and antioxidant/anti-inflammatory functionality on dental pulp stem cells (DPSCs) and macrophages. Then, 15% (w/v) GelMA was formulated with MSNs-COOH-BA (10 or 20 mg/mL). Hydrogels were characterized by SEM/EDS for their microstructure morphology and chemical composition, as well as for compression, swelling, degradation, and BA release. Biological assessments included DPSC cytocompatibility and early mineralization responses under or without LPS stimulation, macrophage cytokine modulation, and <em>in vivo</em> subcutaneous biocompatibility in rats. Statistical analysis used ANOVA/post-hoc tests (α = 5%). BA was non-cytotoxic (≥70% viability at 24 h), enhanced mineralized nodule formation under both basal and inflammatory conditions, reduced intracellular ROS levels, and suppressed TNF-α, IL-1α, and IL-6 production in a dose-responsive manner. GelMA maintained its porous architecture after MSN incorporation. Although BA-functionalized MSNs showed some nanosphere clustering, they reinforced mechanical performance, with MSNs-COOH-BA (20 mg/mL) increasing Young's modulus and ultimate compressive strength relative to GelMA and outperforming MSNs without BA. MSNs-containing hydrogels displayed moderated swelling and slower enzymatic mass loss <em>versus</em> GelMA alone. BA was released over 10 days, and eluates remained non-cytotoxic (&lt;30% reduction <em>vs</em> control).

The GelMA/MSNs-COOH-BA hydrogel paired sustained BA delivery with mechanical integrity, cytocompatibility, anti-inflammatory activity, and early pro-odontogenic cellular responses, supporting its promise as an injectable biomaterial with clinically relevant therapeutic properties for preserving pulp vitality while supporting the dentin-pulp complex's intrinsic repair and development abilities.</div></div>","PeriodicalId":51111,"journal":{"name":"Materials Science & Engineering C-Materials for Biological Applications","volume":"183 ","pages":"Article 214768"},"PeriodicalIF":6.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146191617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The oral drug administration is preferred for its convenience. However, the oral route faces challenges, including the first-pass metabolism and delayed onset of action. Therefore, the transdermal drug delivery system (TDDS) offers an alternative approach to overcome these limitations. This work developed an iontophoresis-based transdermal patch using LCB and XG hydrogel as the drug matrix. In addition, PAIn:PSS was synthesized and employed as the drug carrier, whereas Imatinib was used as the model drug. LCB:XG hydrogels were fabricated at the various weight ratios. The LCB:XG (60:40%w/w) hydrogel exhibited the largest pore size (261.3 ± 67.3 μm). In-vitro release and permeation studies demonstrated that a lower XG ratio resulted in increased Imatinib release. Additionally, incorporating PAIn:PSS further enhanced the release efficiency. Applying an electric field significantly improved drug permeation due to the electrorepulsion which promoted the transport of drug molecules across the skin. Additionally, the permeated release at the pH of 5.5 was slightly lower than that at the pH of 7.4; this can be attributed to the increased positive charge of Imatinib reducing skin permeation due to increased hydrophilicity. Cytotoxicity tests revealed that incorporating PAIn:PSS into the hydrogel patch maintained the high cell viability of 84%, confirming that the hydrogel patch was safe for human tissues. These findings highlight the potential of LCB:XG hydrogel-based transdermal patches combined with PAIn:PSS and iontophoresis for the controlled drug release and efficient Imatinib transdermal delivery.</div></div>","PeriodicalId":51111,"journal":{"name":"Materials Science & Engineering C-Materials for Biological Applications","volume":"183 ","pages":"Article 214730"},"PeriodicalIF":6.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146081885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces β-cyclodextrin-modified gold nanoclusters (CGNCs) as a nanocarrier for efficient delivery of ICA. The synthesized ICA-loaded CGNCs (ICA-CGNCs) have a hydrodynamic diameter of approximately 2.16 nm, demonstrating excellent dispersity, sustained release kinetics, and storage stability.

In MC3T3-E1 cells, ICA-CGNCs promoted osteogenic differentiation, as indicated by increased ALP activity, enhanced mineralization, and upregulated osteogenic genes <em>(ALP, BMP2, RUNX2, and COL1A1</em>); immunofluorescence further showed elevated nuclear β-catenin and RUNX2 signals, supporting the involvement of osteogenic pathway-associated events in this cell model.
