Novel Antibacterial Modification of Polycarbonate for Increment Prototyping in Medicine. MATERIALS 2021; 14:ma14164725. [PMID: 34443247 PMCID: PMC8400390 DOI: 10.3390/ma14164725] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/28/2021] [Revised: 08/12/2021] [Accepted: 08/18/2021] [Indexed: 12/13/2022]
Abstract
In the era of modern medicine, the number of invasive treatments increases. Artificial devices used in medicine are associated with an increased risk of secondary infections. Bacterial biofilm development observed on the implanted surface is challenging to treat, primarily due to low antibiotics penetration. In our study, the preparation of a new polycarbonate composite, filled with nanosilver, nanosilica and rhodamine B derivative, suitable for three-dimensional printing, is described. Polymer materials with antimicrobial properties are known. However, in most cases, protection is limited to the outer layers only. The newly developed materials are protected in their entire volume. Moreover, the antibacterial properties are retained after multiple high-temperature processing were performed, allowing them to be used in 3D printing. Bacterial population reduction was observed, which gives an assumption for those materials to be clinically tested in the production of various medical devices and for the reduction of morbidity and mortality caused by multidrug-resistant bacteria.

Abstract
Abiotic stress is the main cause of low productivity in plants. Therefore, it is important to detect stress and respond to it in a timely manner to avoid irreversible damage to plant productivity and health. The application of traditional methods in agriculture is limited by expensive equipment and cumbersome sample processing. More effective detection methods are urgently needed due to the trace amounts and low stabilities of plant biomarkers. Electrochemical detection methods have the unique advantages of high accuracy, a low detection limit, fast response and easy integration with systems. In this review, the application of three types of electrochemical methods to phytohormone assessment is highlighted including direct electrochemical, immunoelectrochemical, and photoelectrochemical methods. Research on electrochemical methods for detecting abiotic stress biomarkers, including various phytohormones, is also summarized with examples. To date, the detection limit of exogenous plant hormones can reach pg/mL or even lower. Nevertheless, more efforts need to be made to develop a portable instrument for in situ online detection if electrochemical sensors are to be applied to the detection of the endogenous hormones or the physiological state of plants. Additionally, plant-wearable sensors that can be directly attached to or implanted into plants for continuous, noninvasive and real-time monitoring are emphasized. Finally, rational summaries of the considered methods and present challenges and future prospects in the field of abiotic stress detection-based electrochemical biosensors are thoroughly discussed.

Abstract
A simple and accurate label-free amperometric immunosensor for α-fetoprotein (AFP) detection is developed based on gold nanorods (GNRs) with different aspect ratio and compared with gold particles (GNPs). The positively charged GNRs and GNPs due to the surface immobilized cetyltrimethyl ammonium bromide (CTAB) can adsorb the negatively charged AFP antibody (Ab) directly. The presence of the GNRs not only enhanced the immobilized amount of biomolecules, but also improved the electrochemical properties of the immunosensor. With the aid of GNRs, the electrochemical signal was greatly enhanced in comparison with GNPs. Under optimal conditions, the proposed immunosensor could detect AFP in a linear range from 0.1 to 200 ng/mL with a detection limit of 0.04 ng/mL (signal-to-noise ratio = 3), and it also possessed good reproducibility and storage stability. Moreover, the detection of AFP in five human serum samples also showed satisfactory accuracy. The proposed methodology was potentially attractive for clinical immunoassay.

Abstract
A new electrochemical immunoassay strategy for direct detection of carcinoembryoninc antigen (CEA) in serum was developed by using multiarmed star-like platinum nanowires (PtNWs) with biomolecular assembly as signal tags on an anti-CEA-functionalized graphene sensing platform. Initially, the PtNWs were synthesized via a wet chemical method, and then the synthesized PtNWs were used for the co-immobilization of CEA and horseradish peroxidase (HRP). Compared with platinum nanoparticles, the prepared PtNWs could provide a large room for the conjugation of HRP and CEA. With a competitive-type immunoassay format, the assay was performed in two types of supporting electrolytes including new born cattle serum (NBCS) and acetate buffer solution (ABS, pH 5.5), respectively. Similar detection limit (LOD) of 5.0 pg mL(-1) vs. 1.0 pg mL(-1) but narrower dynamic working linear range of 0.01-60 ng mL(-1) vs. 0.002-80 ng mL(-1) was obtained toward CEA standards in the NBCS compared to the ABS. The intra-assay coefficients of variation (CVs) were 4.3%, 8.6%, and 6.2% at 0.05, 10, and 40 ng mL(-1) CEA, respectively, while the inter-assay CVs were 7.6%, 10.5%, and 8.9% at the above-mentioned levels, respectively. In addition, the selectivity and stability of the electrochemical immunosensor were acceptable. Importantly, the developed method was used to assay clinical serum specimens, receiving a good relation with those obtained from the referenced method.
