“…, anticipating plentiful applications in MIPs sensors development, mostly by using nanoparticles as substrate. In particular, the imprinting of small molecules (0.1 kDa < MW < 1 kDa) has regarded amino acids [33], estrogens [34], flavorings [37], colorants [38], phenolic acids [39], toxins [44], antibiotics [45], sugars [46], and chemotherapeutic agents in cancer [47]. Notably, it has been reported that the release of an anticancer molecule imprinted on PDA-coated Fe 3 O 4 nanoparticles increases in presence of a magnetic field, resulting in an effective control of tumor growth in animal models [47], thus paving the way for future studies and applications of MIPs on magnetic substrates.…”

Polydopamine: surface coating, molecular imprinting, and electrochemistry—successful applications and future perspectives in (bio)analysis

Dopamine oxidation and self-polymerization has recently gained a large interest arising from the versatile chemistry of this endogenous catecholamine. Particularly stimulating appear the applications of this biopolymer for surface coating, molecular imprinting, and electrochemistry, here reviewed, covering the broad fields of medicine, material science, and (bio)analytical chemistry.Nonetheless, the peculiar physicochemical properties of dopamine and its polymer, due to the reduction potential of catechol moiety, are not fully exploited. We have confidence in possibility to spread its applications through a large variety of research approaches, including the use of naturally occurring or synthetic dopamine analogues and co-polymers. Accordingly, our efforts in this direction are focused in proposing the role of this polymer for quantitative applications, evaluating analytical performances, costs, reproducibility and versatility of the developed methods also revisiting standard (bio)analytical platforms.

ZnO nanorod arrays (ZNAs) with vertically-aligned orientation were obtained by a two-step aqueous solution method. The morphology of the ZnO nanorods was regulated by changing the precursor concentration and the growth time of each step. ZnO nanorods with distinct structures, including flat top, cone top, syringe shape, and nail shape, were obtained. Moreover, based on the X-ray diffraction (XRD) and the transmission electron microscope (TEM) analysis, the possible growth mechanisms of different ZnO nanostructrues were proposed. The room-temperature PL spectra show that the syringe-shaped ZNAs with ultra-sharp tips have high crystalline quality. Our study provides a simple and repeatable method to regulate the morphology of the ZNAs.

As a new type of 2D material, black phosphorus (BP) has been gradually attracting attentions since it was rediscovered in 2014 because of its many excellent properties, such as strong anisotropic properties, optical‐response properties, layer‐dependent bandgap, and so on. 2D BP is becoming an excellent candidate in the fields of electronics, optics, and so on. However, the applications of 2D BP are greatly limited and challenged by many adverse factors, such as the low yield, poor stability, and high price of BP nanosheets (NSs). Among them, the poor stability of BP is an important factor, which is an urgent problem to be solved. The main reason for its poor stability is the instability of its environment. The degradation factors of 2D BP are studied, including photoinduced degradation and water‐catalyzed degradation. At present, some feasible methods are explored to improve the degradation, which include passivation, surface functionalization, and doping metal or nonmetal ions. This review not only clarifies the structure, properties, degradation mechanism, and methods to improve the BP stability, but also shows more strategic means for the design and application of stable BP‐based nanocomposite materials in the fields of electronics, optics, biomedicine, and fire safety.
