Abstract Stimuli‐responsive materials have the potential to enable generation of new bioinspired devices with unique physicochemical properties and cell‐instructive ability. Enhancing biocompatibility while simplifying production methodologies, as well enabling creation complex constructs, i.e., via 3D (bio)printing technologies, remains key challenge in field. Here, a novel method is presented biofabricate cellularized anisotropic hybrid hydrogel through mild biocompatible process driven by...
Abstract Amyloid supramolecular assemblies have found widespread exploitation as ordered nanomaterials in a range of applications from materials science to biotechnology. New strategies are, however, required for understanding and promoting mature fibril formation simple monomer motifs through easy scalable processes. Noncovalent interactions are key forming holding the amyloid structure together. On other hand, halogen bond has never been used purposefully achieve control over...
In recent years, the presence of numerous xenobiotic substances, such as antibiotics, has been detected in water environments. They can be considered environmental contaminants, even if their effect on human health yet to totally understood. Several approaches have studied for removal these kinds pollutants. Among compounds, tetracycline (TC), a broad-spectrum antibiotic, is one most commonly found due its widespread use. context reducing TC aqueous solution, this contribution, composite...
We describe the electrosynthesis of a molecularly imprinted polymer (MIP) based on metallo-porphyrin, namely Zn(II)− 5,10,15,20-tetrakis-(p-aminophenyl)-porphyrin (ZnTAPP), as new artificial receptor for recognition carnosine (β-Ala--His), used model dipeptide. The MIP architecture has been selected with aim to exploit metal-ion mediated leveraging ability chelate metal ions Zn(II) through its histidine moiety. Metal ion coordination in imprinting procedures is beneficial it combines...
Abstract An alkoxy‐substituted poly(phenylene thiophene) is used in order to suspend single‐walled carbon nanotubes an organic solvent. The suspension spread on the air–water interface of a Langmuir trough and floating film characterized by means Brewster angle microscopy UV‐visible reflection spectroscopy compression isotherm recorded. polymer/carbon‐nanotube blend transferred onto different substrates using Langmuir–Blodgett technique. AFM measurements indicate formation globular...
A porous collagen-based hydrogel scaffold was prepared in the presence of iron oxide nanoparticles (NPs) and characterized by means infrared spectroscopy scanning electron microscopy. The hybrid then loaded with fluorescein sodium salt as a model compound. release hydrosoluble species triggered accurately controlled application an external magnetic field, monitored fluorescence spectroscopy. biocompatibility proposed matrix also tested MTT assay performed on 3T3 cells. Cell viability only...
The Bigger PictureDirected self-assembly (DSA) is probably the most promising strategy for high-volume cost-effective manufacturing at nanoscale to support ever-growing needs of semiconductor market. DSA exploits spontaneous block copolymers onto lithographically nanopatterned surfaces, resulting in large-area fabrication periodic nanostructures on scale a few tens nanometers. Tailoring structure, periodicity, and orientation copolymer crucial requires control over features such as volume...
Perylene bisimide derivatives show peculiar physical chemical features, such as a highly conjugated system, high extinction coefficients and elevated fluorescence quantum yields, making them suitable for the development of optical sensors compounds interest. In particular, they are characterized by tendency to aggregate into π–π stacked supramolecular structures. this contribution, behavior PBI derivative N,N′-bis(2-(trimethylammonium)ethylene)perylene dichloride was investigated both in...
Functionalized plasmonic nanostructure platforms are widely used for developing optical biosensors and SERS assays. In this work, we present a low-cost scalable surface-enhanced Raman scattering (SERS) system based on an innovative transducer comprising gold nanoparticles (AuNPs) embedded in nano-fibrillated bacterial cellulose (BC). The AuNPs@BC composite leverages the unique nanofibrillar architecture of cellulose, which provides high surface area, flexibility, uniform nanoparticle...

Enantiorecognition of a chiral analyte usually requires the ability to respond with high specificity one two enantiomers compound. However, in most cases, sensors have chemical sensitivity toward both enantiomers, showing differences only intensity responses. Furthermore, specific receptors are obtained synthetic efforts and limited structural versatility. These facts hinder implementation many potential applications. Here, we utilize presence each receptor introduce novel normalization that...
Thin films consisting of two fulleropyrrolidine derivatives 1 or 2 and a water-soluble porphyrin, TPPS4, were prepared by the Langmuir−Schäfer (LS, horizontal lifting) method. In particular, solution in chloroform dimethyl sulfoxide was spread on water surface, while porphyrin (bearing peripheral anionic sulfonic groups) dissolved into aqueous subphase. To best our knowledge, such versatile method for film fabrication fullerene/porphyrin mixed composite has never been used other researchers....
