The present study proposes a dual-wavelength ultrashort-pulsed laser system for the direct restoration of damaged enamel to overcome marginal defects. The 2D finite element (FE) laser-ablative model is developed for studying the laser-tissue interaction. The laser-ablated cavities (rectilinear and circular) are prepared on human enamel using 800 nm, Ti:Sapphire femtosecond (fs) laser (100 fs, 1 kHz, 1 mm s<sup>−1</sup>) at average laser power of 200 mW. Subsequently, the cavity is filled with 3D printed biocomposite (65 wt.% of 3D-printing resin and 35 wt.% of Ce<sup>3+</sup>-ion doped hydroxyapatite) and photocured using 405 nm laser. Further, the postprocessing procedure is carried out using fs laser to remove excessive filler materials and improve surface finish at sub-ablation threshold of enamel. The surface morphology, chemical compositions, mechanical and interfacial properties of restored enamel surface are evaluated. The in vitro evaluation study confirmed that the enamel restored with fs laser and 3D printing biocomposite is mechanically and chemically robust for withstanding oral challenges. The proposed method of restoring damaged enamel opens an opportunity for a range of precision restorative dentistry procedures including caries and tooth augmentation.</p>","PeriodicalId":7292,"journal":{"name":"Advanced Materials Technologies","volume":"10 9","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admt.202401362","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, incorporating hydrogel components inside conventional PDMS-based microfluidic chips is a promising approach to take advantage of the many possibilities to utilize hydrogels, while maintaining standard properties of microfluidic devices in terms of mechanical stability. Microfluidic chips produced by standard soft lithography are combined with high-resolution protein-based hydrogel elements fabricated by two-photon polymerization (2PP). Those hybrid chips are used to distinguish mechanical properties of different cell phenotypes by injecting pancreatic cancer cells inside the device and investigate mechanical interactions with the hydrogel microstructures. The Young's modulus of blocks printed at different experimental conditions is determined by atomic force microscopy measurements. To showcase the high 3D resolution of the presented fabrication method, fully 3D fibrous meshes are printed with different configurations inside microchannels. By measuring the velocity and circularity of pancreatic cancer cells that pass through meshes of varying densities, the impact on the cell flow is determined.

However, their fabrication is often reliant on environmentally deleterious methods and materials that overshadow the environmental benefits the devices provide. Toward improving the overall environmental footprint of devices, stretchable and conductive substrates for enabling wearable electronics are fabricated predominately from both sustainable and biodegradable materials (chitosan and sorbitol) along with an environmental benign solvent: water. Indeed, the >95 wt.% of the stretchable and bendable sensor consists of sustainable and biodegradable materials. By blending a collectively self-doped and water-soluble conductive homopolymer during processing, stretchable films with a transverse resistance as low as 0.08 MΩ are obtained. Both the conductivity and mechanical properties of the films including elongation at break and Young's modulus are contingent on the chitosan molecular weight. The elongation at break of the films prepared from high molecular weight chitosan is upward of 200%, with the optical transmission of 60% above 500 nm, and minimal conductive hysteresis with stretching. Both the mechanical compliance and conductivity of the sustainable films are ideal for enabling wearing electronics.

Nevertheless, there is significant clinical demand for synthetic soft–hard interfaces. Here, soft–hard interface geometries are proposed, designed with the aid of computational analyses and fabricated as 3D-printed hydrogel-to-polylactide (PLA) structures. Two primary interlocking geometries (i.e., anti-trapezoidal (AT) and double-hook (DH)) are used to study the envelope of 2.5D geometric interlocking designs, fabricated through hybrid 3D printing, combining pneumatic extrusion with fused deposition modeling. Finite-element analysis, uniaxial tensile tests, and digital image correlation (DIC) are used to characterize the geometries and identify parameters that significantly influence their mechanical performance. These findings reveal significant differences between geometric designs, where DH geometries performed significantly better than AT geometries, exhibiting a 190% increase in the maximum force, <i>F</i><sub>max</sub>, and a 340% increase in the fracture toughness, <i>W</i>. Compared to the control groups (i.e., flat, inset, and 90° interfaces), <i>F</i><sub>max</sub> and <i>W</i> values increased by 500%–990% and 350%–1200%, respectively.
