In this study, a nanobody (VHH) was developed with improved tolerability and higher specificity for the target. The strong binding affinity between VHH and survivin was emphasized by simulated docking, demonstrating the feasibility and effectiveness of replacing mAb in the detection of urinary survivin based on LFIA. In addition, the superior performance of VHH compared with mAb under extreme conditions was highlighted. To further enhance the detection performance, VHH was conjugated with an Au nanoparticle cluster (AuNP cluster). The pore size structure of the AuNP cluster led to an increased abundance of AuNPs, which amplified the signal while providing adequate adsorption sites for VHH coupling, thereby achieving a synergistic enhancement in the sensitivity and specificity of the AuNP cluster-VHH probe. Consequently, the detection limit for survivin was established at 3.90 ng/mL, facilitating noninvasive detection and monitoring in early-stage bladder cancer and during post-treatment surveillance.

We exploit biologically derived rigid nanofibers as a multifunctional modality in a robust micromolding method using a postfabrication bioconjugation approach to address this challenge. Specifically, chitin-core chitosan-sheath nanowhiskers (CSNW) with a tunable amine titer are prepared under mild deacetylation reaction conditions. Transmission electron microscopy, dynamic light scattering, and dynamic viscosity measurements show rigid bionanofibers with substantially lower viscosity compared to solubilized linear forms of chitosan and other biopolymers, suggesting improved handling and manufacturability. Fluorescent labeling studies on polyacrylamide-based microspheres fabricated via micromolding indicate stable and uniform incorporation of CSNW in hydrogel microspheres and the readily tunable chemical functionality of CSNW. Further, reliable fabrication using acrylate-modified CSNW as the primary cross-linker, along with selective and improved protein conjugation kinetics, attests to the macroporous network of the hydrogel microparticles and illustrates the multifunctionality of CSNW. We thus envision that our approach in harnessing potent bionanofibers and micromolding can be readily extended to produce a wide variety of multifaceted microscale materials with a multitude of desirable features with improved performances for applications such as rapid biosensing and biodiagnostics.</p>","PeriodicalId":2,"journal":{"name":"ACS Applied Bio Materials","volume":" ","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144511240","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}

However, the limited mechanical and tribological properties of PEGDA constrain its application in load-bearing tissue engineering. To address the challenges associated with the limited mechanical and tribological properties of PEGDA, an attempt has been made to enhance its performance by incorporating an inorganic nanofiller hexagonal boron nitride (hBN). Here, stereolithography (SLA), an additive manufacturing technique, was used to synthesize the hBN-reinforced PEGDA nanocomposite, rendering superior mechanical, thermal, and tribological properties. PEGDA and phenylbis (2,4,6-trimethylbenzoyl) phosphine oxide (BAPOs) photoinitiator were mixed with hBN nanoplatelets (with varying concentrations of 0.25%, 0.50%, 0.75%, and 1.0% w/w) to prepare a composite resin. The SLA-printed PEGDA and hBN/PEGDA nanocomposites were characterized meticulously by using mechanical, physical, thermal, and tribological characterization techniques. As a result, hBN-incorporated PEGDA nanocomposite samples demonstrated significant improvement in the tensile, compressive, and flexural strength at 71.62%, 76.22%, and 31.89%, respectively, compared to that of pristine PEGDA. The fractography of the fractured surfaces revealed a pure brittle fracture in both pristine PEGDA and hBN/PEGDA nanocomposite samples. In addition to evaluating mechanical strength, the tribological performance of PEGDA and its hBN-reinforced nanocomposites was also assessed, revealing a substantial reduction in wear and frictional force upon nanofiller incorporation. The 3D printed samples were also characterized by differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR), and wettability test. DSC thermograms and wettability measurements indicated that both the glass transition temperature and the hydrophilicity of the nanocomposites increased with higher hBN weight concentrations. Furthermore, the antibacterial property tests were conducted with two Gram-positive and Gram-negative bacteria, and it was found that the hBN-incorporated PEGDA composite resin inhibits antimicrobial properties.</p>","PeriodicalId":2,"journal":{"name":"ACS Applied Bio Materials","volume":" ","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144493096","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}

However, many late-stage NSCLC patients exhibit drug resistance and experience significant side effects from current chemotherapy agents, ultimately leading to disease progression. Consequently, the development of strategies to enhance efficacy while minimizing side effects through multimodal synergistic treatment technologies remains challenging. Here, we prepared a stable multifunctional nanocomplex, PLGA@DTX@Fe³⁺-TA/GO_X (PDFTG), which utilizes poly(lactic acid-<i>co</i>-glycolic acid) (PLGA) nanoparticles to encapsulate docetaxel (DTX) as the core component, while a Fe³⁺-tannic acid (TA) nanonetwork serves as the outer coating. Additionally, interactions between polyphenols and proteins facilitate the loading of glucose oxidase (GO_X). After intravenous injection, PDFTG selectively accumulates in the tumor region, subsequently releasing Fe³⁺, TA, DTX, and GO_X, thereby remodeling the tumor microenvironment. Following this process, Fe³⁺ is reduced to Fe²⁺ by TA, leading to mitochondrial damage in cancer cells and resulting in an increase in O₂ content. This increase promotes the GO_X-catalyzed glucose oxidation reaction that generates gluconic acid and H₂O₂, initiating starvation therapy. The gluconic acid enhances the acidity of the microenvironment, further promoting the release of PDFTG nanoparticles and enhancing the accumulation of H₂O₂ within the cell. The accumulated H₂O₂ reacts with Fe²⁺ in a strongly acidic environment, leading to the of hydroxyl free radicals that initiate chemical dynamic therapy (CDT). Moreover, mitochondrial damage results in a reduction of adenosine triphosphate levels, which decreases the expression of P-glycoprotein, thereby reversing DTX resistance and producing potent multimodal synergistic antitumor effects.
