Though 3D bioprinting technologies are widely used in the creation of artificial tissues and organs, very little research has been done on their biosensor applications. Single-walled carbon nanotube (SWNT)-based optical sensors are highly praised for their remarkable sensitivity and specificity for a wide range of analytes. Nevertheless, due to the complexity of packaging and immobilization, problems continue to arise when incorporating SWNT sensors into both in vitro and in vivo applications. Herein, we report the use of 3D printing technology to improve SWNT sensor integration, resulting in adaptable and efficient platform designs. The optimized bioprinted hydrogel, composed of 3D-printable, modified Pluronic F-127, improves SWNT containment, ensuring stable fluorescence readings and increased fluorescence quenching in the presence of nitric oxide (NO). The hydrogel-encapsulated sensor maintains a ~95% fluorescence intensity over 90 days. Following the hydrogel parameter optimization, NO solutions were introduced to a 1.5-mm thick walled 30 mg/L SWNT-loaded hydrogel, revealing a gradual fluorescence intensity decrease with higher NO concentrations. Analysis shows a logarithmic relationship in the percentage of quenching at 990 nm within the concentration range of 1 μM to 50 μM, with the limit of detection (LOD) of 0.431 μM. When inserted under chicken skin, the sensor exhibits stable fluorescence readings, demonstrating its potential as a real-time in vivo sensor for minimally invasive health monitoring.</p>","PeriodicalId":11536,"journal":{"name":"Emergent Materials","volume":"8 2","pages":"1111-1120"},"PeriodicalIF":4.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12965751/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147376508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to the low mass transfer attributable to agglomeration, reduction in pore accessibility, and sample loss, the powdered samples face challenges translating from lab to pilot scale. Conversely, the structuring of composites in beads and pallets can modify the surface chemistry and adsorption mechanism. To investigate the impact of structuring, a comparative analysis of pure, calcium chloride (CaCl₂)-impregnated activated carbon (AC) powder and CaCl₂-crosslinked AC beads was conducted in this work, to observe the ramification of surface chemistry due to salt distribution, porosity, surface area and pH-controlled crosslinking, on ammonia adsorption. The role of pH in bead formation introduced a new dimension in tailoring ammonia adsorption efficiency. The bead sample containing 20% CaCl₂ (AC-B (20%)), with pH-8 crosslinking solution, has shown the two times more ammonia adsorption due to optimum crosslinking, physicochemical interactions and the presence of tuned amount of calcium chloride (CaCl₂) on the surface and pores. SEM, XRD, FTIR, BET, DFT, and XPS are used to analyse the fabricated samples before and after the adsorption to thoroughly investigate the adsorption mechanism. The kinetic analysis of experimental results was conducted by applying nonlinear Pseudo 1^st order (PFO), Pseudo 2^nd order (PSO), and Elovich models, with best fit with N-PSO model confirming the highest mass transfer by the bead sample (AC-B (20%)). Lastly, the economic feasibility analysis as well as the impact of thermal treatment on recovery and sample regeneration was studied by desorbing the best samples at four different temperatures (120 °C, 140 °C, 160 °C, and 180 °C).</p><p><strong>Graphical abstract: </strong></p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s42247-025-01106-8.</p>","PeriodicalId":11536,"journal":{"name":"Emergent Materials","volume":"8 6","pages":"5217-5240"},"PeriodicalIF":4.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12528320/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145328378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
