It is well known that nature provides guidance and inspiration for the design and molecular tailoring of functional peptide sequences, which can further self-assemble into complex peptide nanomaterials with adjustable dimensions. In this mini-review, we summarize recent advances in the bioinspired design and regulation of functional peptide sequences by natural things, such as mussels, milk protein, silkworm silk, frogs and Alzheimer’s disease. The self-assembly of bioinspired peptides in vitro and in vivo for controlled synthesis of various peptide-based nanomaterials is introduced and analyzed. In addition, various applications of biomimetic peptide nanomaterials for biosensors, bioimaging, cancer therapy, antibacterial materials, tissue engineering, as well as energy storage and environmental science are demonstrated in detail. Finally, we give perspectives on the future development of this promising research topic. With these efforts, we hope to promote the understanding of the optimization of bioinspired peptides and the design of novel peptide nanomaterials for advanced applications.","PeriodicalId":54222,"journal":{"name":"Nano Futures","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2023-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42827251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sequential layer deposition can lead to the creation of complex parts with minimized material waste, high manufacturing throughput, and increased prototyping ability, while also meeting the demand for mid- and low-volume production. The AM of polymer nanocomposites is a growing area of research because nanomaterial additives can enhance the mechanical, electrical, and other properties for end-use applications. However, the use of nanomaterial inclusions can also enhance the AM processes themselves. Here, we discuss works where nanomaterials are employed as local heaters for fused deposition modeling, as viscosifiers for direct ink writing, and as photothermal sensitizers for selective laser sintering and vat polymerization. We also note the disconnect between the researched AM capabilities and current industrial manufacturing; nanomaterials can bridge the technological gap and lead to new common practices in industrial manufacturing spaces.","PeriodicalId":54222,"journal":{"name":"Nano Futures","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47832293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the presence of π -conjugated planar structure, these materials were reported to quench the chemiluminescence (CL) signal. Based on this fact, herein, for the first time, the recovery of quenched CL signal from different graphene-based materials is successfully obtained through the catalytic activity of onsite temperature. The maximum recovery of a quenched signal at an optimum temperature of 70 ∘C was 1440% from the 10 mg ml−1 reduced graphene oxide paper analytical devices. The recovery of flash graphene and laser induced graphene materials were found to be 895% and 521%, respectively, for the same conditions via the generation of π -conjugated carbon radicals. Catechin, an antioxidant, was analyzed from 0.1 nM to 500 nM to interpret the generation of carbon radicals from graphenized materials. The proposed smartphone-enabled onsite heating recovery model was validated with the lower limit of 94 pM (27.3 pg ml−1) of catechin concentration without advanced photodiodes or instrumentation. The validation was performed in real samples of green tea (1 and 2). This method of CL recovery can be a future model for indicating the purity of graphene-based materials without using advanced instrumentations.","PeriodicalId":54222,"journal":{"name":"Nano Futures","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47654687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, Na+ ions with larger radius are doped into LiNi1/3Co1/3Mn1/3O2 (LNCMO) single-crystal nanoparticles through a simple sol–gel method to further improve the rate capability. Different amounts of Na doping are considered to illustrate the cooperative effect of single-crystal structure and Na doping. The results indicate that a Li0.9Na0.1Ni1/3Co1/3Mn1/3O2 cathode has a discharge capacity of 193.7 mAh g–1 at 0.2 C, much higher than the 174.8 mAh g–1 of its undoped counterpart. After 50 cycles, the capacity retention is enhanced from 71.3% for undoped LNCMO to 89.2% for Li0.9Na0.1Ni1/3Co1/3Mn1/3O2. At the same time, Li0.9Na0.1Ni1/3Co1/3Mn1/3O2 delivers a discharge capacity of 137.9 mAh g–1 at 10 C, about twice the capacity of LNCMO. Na ions doped into the lattice can magnify the distances between lithium layers and act as pins for more stable structure and faster kinetics of Li+-ion diffusion.","PeriodicalId":54222,"journal":{"name":"Nano Futures","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41664021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the current investigation, novel magnetic nanocomposites containing copper ferrite (CuFe2O4) and gelatin-derived carbon quantum dots (CQDs) were successfully synthesized. The prepared nanocatalyst was characterized by scanning electron microscopy, x-ray diffraction, transmission electron microscopy, Brunauer–Emmet–Teller (BET), Fourier transform infrared and ultraviolet–visible techniques. The mesoporous structure of the CuFe2O4/CQD nanocomposite was shown using the BET/Barrett–Joyner–Halenda technique. The catalytic performance of the nanocatalyst during the reduction of PNA and ONA was assessed in an aqueous medium at 25 °C. The complete reduction of PNA and ONA using the CuFe2O2/CQDs nanocomposite occurred in 13 s and 35 s, respectively. The pseudo-second-order rate constant (K app) was obtained as 2.89 × 10−1 s−1 and 9.3 × 10−2 s−1 for reducing PNA and ONA, respectively. Moreover, the magnetic nanocatalyst was easily separated from the reaction solution and recycled for up to six consecutive cycles without significant loss of catalytic activity.","PeriodicalId":54222,"journal":{"name":"Nano Futures","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43238137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
