Abstract
Nanomaterials have been explored in the sensing research field in the last decades. Mainly, 3D nanomaterials have played a vital role in advancing biomedical applications, and less attention was given to their application in the field of biosensors for pathogenic virus detection. The versatility and tunability of a wide range of nanomaterials contributed to the development of a rapid, portable biosensor platform. In this review, we discuss 3D nanospheres, one of the classes of nanostructured materials with a homogeneous and dense matrix wherein a guest substance is carried within the matrix or on its surface. This review is segmented based on the type of nanosphere and their elaborative application in various sensing techniques. We emphasize the concept of signal amplification strategies using different nanosphere structures constructed from a polymer, carbon, silica, and metal-organic framework (MOF) for rendering high-level sensitivity of virus detection. We also briefly elaborate on some challenges related to the further development of nanosphere-based biosensors, including the toxicity issue of the used nanomaterial and the commercialization hurdle.

Gong A, Zhao Y, Liang B, Li K. Stepwise hollow Prussian blue/carbon nanotubes composite as a novel electrode material for high-performance desalination. J Colloid Interface Sci 2021; 605:432-440. [PMID: 34332416 DOI: 10.1016/j.jcis.2021.07.103] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2021] [Revised: 06/27/2021] [Accepted: 07/19/2021] [Indexed: 10/20/2022]
Abstract
As a promising intercalation material for capacitive deionization (CDI), Prussian blue (PB) and its analogues (PBAs) have the superiority of high theoretical capacity and easy synthesis. But they often suffer from low conductivity and severe crystal phase transition, resulting in inferior desalination capacity and poor cycling stability. Herein, the dual strategy of structural optimization and carbon-based materials introduction is proposed to enhance the desalination performance of PBAs. Stepwise hollow structure formed by surface etching has been proved to be more outstanding than cubic structure. Enlarged the specific surface area, the contact area with the electrolyte increases, therefore, more active sites are exposed. Besides, the etching of external surfaces provides more buffer space, improves the tolerance to crystal phase transition, and enhances the cycling stability. The introduction of carbon nanotubes brings high conductivity. Specifically, the desalination test shows that stepwise hollow Prussian blue/carbon nanotubes composite delivers a high desalination capacity of 103.4 mg g-1 with outstanding cycling stability. Moreover, the low energy consumption of 0.23 Wh g-1 is also suitable for practical application. The dual strategy opens a window to design advanced electrode materials for CDI.

Abstract
The development of sensing coatings, as important sensor elements that integrate functionality, simplicity, chemical stability, and physical stability, has been shown to play a major role in electrochemical sensing system development trends. Simple and versatile assembling procedures and scalability make polyelectrolytes highly convenient for use in electrochemical sensing applications. Polyelectrolytes are mainly used in electrochemical sensor architectures for entrapping (incorporation, immobilization, etc.) various materials into sensing layers. These materials can often increase sensitivity, selectivity, and electronic communications with the electrode substrate, and they can mediate electron transfer between an analyte and transducer. Analytical performance can be significantly improved by the synergistic effect of materials (sensing material, transducer, and mediator) present in these composites. As most reported methods for the preparation of polyelectrolyte-based sensing layers are layer-by-layer and casting/coating methods, this review focuses on the use of the latter methods in the development of electrochemical sensors within the last decade. In contrast to many reviews related to electrochemical sensors that feature polyelectrolytes, this review is focused on architectures of sensing layers and the role of polyelectrolytes in the development of sensing systems. Additionally, the role of polyelectrolytes in the preparation and modification of various nanoparticles, nanoprobes, reporter probes, nanobeads, etc. that are used in electrochemical sensing systems is also reviewed.

Abstract
In the study, folic acid doped Prussian blue nanoparticles (FA-PB NPs) for theranostic applications were synthesized for the first time. Folic acid was chosen for maintaining nanoparticle stability and also to increase its binding affinity especially for cancer cells. Multifunctional PB NPs were fabricated by one route co-precipitation method to synthesize biocompatible NPs without any further process. Then, FA was doped on the surface of PB NPs. The characterization studies demonstrated that the FA-PB NPs modified sensor surface had large surface area with biocompatible and hydrophilic properties where cancer cells can easily bind. The FA-PB NPs were used for the modification of pencil graphite electrode (PGE) for electrochemical detection of colon cancer cells (DLD-1). Electrochemical impedimetric diagnosis was based on the specific interaction between FA groups on the nanoparticles and FA receptors overexpressed on cancer cells. The voltammetric and impedimetric results showed that the FA-PB NPs based electrode had good sensing performance for the immobilized DLD-1 cells.

Abstract
The authors describe a nanocomposite that was obtained by in-situ deposition of CdS nanocrystals on mesoporous silica nanospheres (MSNs), and its use in an electrochemical immunoassay of human immunoglobulin G (HIgG). The MCN/CdS nanocomposite was covalently modified with the antibodies against HIgG and then employed in a voltammetric immunoassay at antibody-functionalized magnetic beads. Through sandwich immunoreaction, the MCN/CdS nanoprobes are quantitatively captured onto the magnetic beads where numerous Cd(II) ions are released in an acidic solution. The Cd(II) can be detected by anodic stripping voltammetry at a typical working potential of -0.78 V (vs. Ag/AgCl). In combination with the high loading of CdS on MSNs, the use of the stripping voltammetric analysis renders the method high sensitivity. A wide linear range varying from 0.01 to 100 ng mL-1 is obtained for HIgG detection with a lower detection limit at 2.9 pg mL-1. In addition, the preparation of the nanoprobe is inexpensive. The magnetic bead-based assay does not require complex manipulations. Therefore, this method is deemed to possess a wide scope in that it may be applied to other immunoassays.

Abstract
With large surface area and three-dimensional pore structure, mesoporous carbon nanoparticles (MCN) have attracted enormous interests as potential drug carriers. However, MCN immunotoxicity has not been clarified clearly up to now. Herein we reported the effect of MCN with and without PVP or DSPE mPEG2000 (PEG) modification on immune cells including dendritic cells (DCs), T lymphocytes and RAW264.7 macrophages in vitro. Furthermore, blood biochemical tests, alexin C3 assay and histological analysis were used to investigate the toxicity of MCN in vivo. The synthesized MCN with average particle size about 90 nm was naturally insoluble in water. Surface modification with PVP (MCN-PVP) or PEG (MCN-PEG) slightly increased the particle size and Zeta potential, and effectively improved the dispersion of mesoporous carbon. MCN, MCN-PVP and MCN-PEG promoted the differentiation and maturation of the DCs, while the levels of secreted TNF-α and IL-6 were significantly suppressed by MCN-PVP and MCN-PEG. These materials significantly induced apoptosis of T lymphocytes. The histopathologic results showed that there was no significant difference between nanoparticles with or without modification. Importantly, the materials deposition was observed in the lung, which could potentially inhibit lung metastasis. In conclusion, the ordered mesoporous carbon nanoparticles superficially modified by PVP or PEG perform well in immunological biocompatibility, and are likely to be a promising candidate as medicine carrier in pharmaceutics and clinic.

Abstract
A novel electrochemical non-enzymatic hydrogen peroxide (H2O2) sensor has been developed based on Prussian blue (PB) and electrochemically reduced graphene oxide (ERGO). The GO was covalently modified on glassy carbon electrode (GCE), and utilized as a directing platform for in-situ synthesis of electroactive PB. Then the GO was electrochemically treated to reduction form to improve the effective surface area and electroactivity of the sensing interface. The fabrication process was characterized by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX) and atomic force microscopy (AFM). The results showed that the rich oxygen containing groups play a crucial role for the successful synthesis of PB, and the obtained PB layer on the covalently immobilized GO has good stability. Electrochemical sensing assay showed that the modified electrode had tremendous electrocatalytic property for the reduction of H2O2. The steady-state current response increased linearly with H2O2 concentrations from 5μM to 1mM with a fast response time (less than 3s). The detection limit was estimated to be 0.8μM. When the sensor was applied for determination of H2O2 released from living cells of macrophages, satisfactory results were achieved.

Abstract
A nanoporous gold nanosphere (pAu NS) was synthesized to load high-content glucose oxidase (GOx) and ferrocene (Fc) for the successful preparation of a new gold nanoprobe. After the specific recognition of the tumor biomarker of carcinoembryonic antigen (CEA) at a gold electrode based aptasensor, this GOx and Fc dually functionalized pAu NS nanoprobe was further used for sandwich immunoreaction and signal tracing. Based on the Fc-mediated GOx-catalytic reaction, the gold nanoprobes quantitatively captured onto the electrode surface produced a sensitive electrochemical signal corresponding to the protein recognition events, which led to the development of a new biosensing method for CEA measurement. Both the high loading of GOx and Fc on the pAu NS nanocarrier and the enzymatically catalytic reaction of the nanoprobe greatly amplify the electrochemical signal; meanwhile, the immobilization of the Fc mediator on this enzyme nanoprobe and the highly specific aptamer recognition drastically decrease the background current, resulting in the achievement of ultrahigh sensitivity of the method. Under optimum conditions, this method shows an excellent analytical performance including a wide linear relationship of five-order of magnitude and a low detection limit down to 0.45 pg mL(-1). Thus this pAu NS based gold nanoprobe and the proposed immunoassay method provide great potential for practical applications.
