SENSORS (BASEL, SWITZERLAND) 2023; 23:s23073685. [PMID: 37050745 PMCID: PMC10099372 DOI: 10.3390/s23073685] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 03/30/2023] [Accepted: 03/31/2023] [Indexed: 05/21/2023]
Abstract
This study presents a glucose biosensor based on electrospun core-sheath nanofibers. Two types of film were fabricated using different electrospinning procedures. Film F1 was composed solely of core-sheath nanofibers fabricated using a modified coaxial electrospinning process. Film F2 was a double-layer hybrid film fabricated through a sequential electrospinning and blending process. The bottom layer of F2 comprised core-sheath nanofibers fabricated using a modified process, in which pure polymethacrylate type A (Eudragit L100) was used as the core section and water-soluble lignin (WSL) and phenol were loaded as the sheath section. The top layer of F2 contained glucose oxidase (GOx) and gold nanoparticles, which were distributed throughout the polyvinylpyrrolidone K90 (PVP K90) nanofibers through a single-fluid blending electrospinning process. The study investigated the sequential electrospinning process in detail. The experimental results demonstrated that the F2 hybrid film had a higher degradation efficiency of β-D-glucose than F1, reaching a maximum of over 70% after 12 h within the concentration range of 10-40 mmol/L. The hybrid film F2 is used for colorimetric sensing of β-D-glucose in the range of 1-15 mmol/L. The solution exhibited a color that deepened gradually with an increase in β-D-glucose concentration. Electrospinning is flexible in creating structures for bio-cascade reactions, and the double-layer hybrid film can provide a simple template for developing other sensing nanomaterials.

Abstract
In recent years, dual-modal immunosensors based on synthetic nanomaterials have provided accurate and sensitive detection. However, preparation of nanomaterial probes can be time-consuming, laborious, and not limited to producing inactive and low-affinity antibodies. These challenges can be addressed through the multifunction nanobody without conjugation. In this study, a nanobody-enhanced green fluorescent (Nb26-EGFP) was novel produced with a satisfactory affinity and fluorescent properties. Then, a dual-modal fluorescent/colorimetric immunosensor was constructed using the Nb26-EGFP-gold nanoflowers (AuNFs) composite as a probe, to detect the aflatoxin B1 (AFB1). In the maize matrix, the proposed immunosensor showed high sensitivity with a limit of detection (LOD) of 0.0024 ng/mL and a visual LOD of 1 ng/mL, which is 20-fold and 325-fold compared with the Nb26-EGFP-based single-modal immunosensor and original nanobody Nb26-based immunoassay. The performance of the dual-modal assay was validated by a high-performance liquid chromatography method. The recoveries were between 83.19 and 108.85%, with the coefficients of variation below 9.43%, indicating satisfied accuracy and repeatability. Overall, the novel Nb26-EGFP could be used as the detection probe, and the dual-modal immunosensor could be used as a practical detection method for AFB1 in real samples.

Abstract
Oral ulcers affect oral and systemic health and have high prevalence in the population. There are significant individual differences in the etiology and extent of the disease among patients. In the treatment of oral ulcers, nanofiber films can control the drug-release rate and enable long-term local administration. Compared to other drug-delivery methods, nanofiber films avoid the disadvantages of frequent administration and certain side effects. Electrospinning is a simple and effective method for preparing nanofiber films. Currently, electrospinning technology has made significant breakthroughs in energy-saving and large-scale production. This paper summarizes the polymers that enable oral mucosal adhesion and the active pharmaceutical ingredients used for oral ulcers. Moreover, the therapeutic effects of currently available electrospun nanofiber films on oral ulcers in animal experiments and clinical trials are investigated. In addition, solvent casting and cross-linking methods can be used in conjunction with electrospinning techniques. Based on the literature, more administration systems with different polymers and loading components can be inspired. These administration systems are expected to have synergistic effects and achieve better therapeutic effects. This not only provides new possibilities for drug-loaded nanofibers but also brings new hope for the treatment of oral ulcers.
