ACS APPLIED MATERIALS & INTERFACES 2024; 16:3139-3146. [PMID: 38197122 PMCID: PMC10811624 DOI: 10.1021/acsami.3c15699] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 12/18/2023] [Accepted: 12/20/2023] [Indexed: 01/11/2024]
Abstract
We report on the design of heteromultivalent influenza A virus (IAV) receptors based on reversible self-assembled monolayers (SAMs) featuring two distinct mobile ligands. The principal layer building blocks consist of α-(4-amidinophenoxy)alkanes decorated at the ω-position with sialic acid (SA) and the neuraminidase inhibitor Zanamivir (Zan), acting as two mobile ligands binding to the complementary receptors hemagglutinin (HA) and neuraminidase (NA) on the virus surface. From ternary amphiphile mixtures comprising these ligands, the amidines spontaneously self-assemble on top of carboxylic acid-terminated SAMs to form reversible mixed monolayers (rSAMs) that are easily tunable with respect to the ligand ratio. We show that this results in the ability to construct surfaces featuring a very strong affinity for the surface proteins and specific virus subtypes. Hence, an rSAM prepared from solutions containing 15% SA and 10% Zan showed an exceptionally high affinity and selectivity for the avian IAV H7N9 (Kd = 11 fM) that strongly exceeded the affinity for other subtypes (H3N2, H5N1, H1N1). Changing the SA/Zan ratio resulted in changes in the relative preference between the four tested subtypes, suggesting this to be a key parameter for rapid adjustments of both virus affinity and selectivity.

Abstract
Cells adhering onto surfaces sense and respond to chemical and physical surface features. The control over cell adhesion behavior influences cell migration, proliferation, and differentiation, which are important considerations in biomaterial design for cell culture, tissue engineering, and regenerative medicine. Here, we report on a supramolecular-based approach to prepare reversible self-assembled monolayers (rSAMs) with tunable lateral mobility and dynamic control over surface composition to regulate cell adhesion behavior. These layers were prepared by incubating oxoacid-terminated thiol SAMs on gold in a pH 8 HEPES buffer solution containing different mole fractions of ω-(ethylene glycol)2-4- and ω-(GRGDS)-, α-benzamidino bolaamphiphiles. Cell shape and morphology were influenced by the strength of the interactions between the amidine-functionalized amphiphiles and the oxoacid of the underlying SAMs. Dynamic control over surface composition, achieved by the addition of inert filler amphiphiles to the RGD-functionalized rSAMs, reversed the cell adhesion process. In summary, rSAMs featuring mobile bioactive ligands offer unique capabilities to influence and control cell adhesion behavior, suggesting a broad use in biomaterial design, tissue engineering, and regenerative medicine.

Abstract
Synthetic receptors to recognize biological glycans are in great need for modern glycoscience and technology, but their design and synthesis have been a daunting challenge due to strong solvation of carbohydrates in water and structural complexity of the guest. Molecular imprinting in surfactant micelles with amide cross-linkers provides a convenient one-pot method to prepare nanoparticle receptors for glycosides, glycans, and glycoproteins, taking advantage of hydrogen-bonding interactions near the surfactant/water interface. Biologically competitive micromolar binding affinities were obtained in water and subtle structural differences of glycans could be distinguished.

Abstract
Exploring new strategies for simple and on-demand methods of manipulating the sensing ability of sensor devices functionalized with artificial receptors embedded in a molecular assembly is important to realizing high-throughput on-site sensing systems based on integrated and miniaturized devices such as field-effect transistors (FETs). Although FET-based chemical sensors can be used for rapid, quantitative, and simultaneous determination of various desired analytes, detectable targets in conventional FET sensors are currently restricted owing to the complicated processes used to prepare sensing materials. In this study, we investigated the relationship between the sensing features of FETs and the nanostructures of mixed self-assembled monolayers (mSAMs) for the detection of biomolecules. The FET devices were systematically functionalized using mixtures of benzenethiol derivatives (4-mercaptobenzoic acid and benzenethiol), which changed the nanostructure of the SAMs formed on gold sensing electrodes. The obtained cross-reactivity in the FETs modified with the mSAMs was derived from the multidimensional variations of the SAM characteristics. Our successful demonstration of continuous control of the molecular recognition ability in the FETs by applying the mSAM system could lead to the development of next-generation versatile analyzers, including chemical sensor arrays for the determination of multiple analytes anytime, anywhere.
