[PMID: 38202662 PMCID: PMC10779547 DOI: 10.3390/molecules29010082] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 12/21/2023] [Accepted: 12/21/2023] [Indexed: 01/12/2024] Open
Abstract
Optical methods (spectroscopy, spectrofluorometry, dynamic light scattering, and refractometry) were used to study the change in the state of hen egg-white lysozyme (HEWL), protein molecules, and gold nanoparticles (AuNPs) in aqueous colloids with changes in pH, and the interaction of protein molecules with nanoparticles was also studied. It was shown that changing pH may be the easiest way to control the protein corona on gold nanoparticles. In a colloid of nanoparticles, both in the presence and absence of protein, aggregation-deaggregation, and in a protein colloid, monomerization-dimerization-aggregation are the main processes when pH is changed. A specific point at pH 7.5, where a transition of the colloidal system from one state to another is observed, has been found using all the optical methods mentioned. It has been shown that gold nanoparticles can stabilize HEWL protein molecules at alkaline pH while maintaining enzymatic activity, which can be used in practice. The data obtained in this manuscript allow for the state of HEWL colloids and gold nanoparticles to be monitored using one or two simple and accessible optical methods.

Abstract
The formation of a protein corona, where proteins spontaneously adhere to the surface of nanomaterials in biological environments, leads to changes in their physicochemical properties and subsequently affects their intended biomedical functionalities. Most current methods to study protein corona formation are ensemble-averaging and either require fluorescent labeling, washing steps, or are only applicable to specific types of particles. Here we introduce real-time all-optical nanoparticle analysis by scattering microscopy (RONAS) to track the formation of protein corona in full serum, at the single-particle level, without any labeling. RONAS uses optical scattering microscopy and enables real-time and in situ tracking of protein adsorption on metallic and dielectric nanoparticles with different geometries directly in blood serum. We analyzed the adsorbed protein mass, the affinity, and the kinetics of the protein adsorption at the single particle level. While there is a high degree of heterogeneity from particle to particle, the predominant factor in protein adsorption is surface chemistry rather than the underlying nanoparticle material or size. RONAS offers an in-depth understanding of the mechanisms related to protein coronas and, thus, enables the development of strategies to engineer efficient bionanomaterials.

Colloids Surf B Biointerfaces 2023; 229:113479. [PMID: 37517337 DOI: 10.1016/j.colsurfb.2023.113479] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 07/18/2023] [Accepted: 07/25/2023] [Indexed: 08/01/2023]
Abstract
Mussel foot proteins (MFPs) hold tremendous potential for various fields, but their low natural production yield presents a significant challenge for practical use. This study aims to explore possible solutions to overcome this limitation. While advanced recombinant technology can improve production efficiency, the resulting proteins lack the crucial chemical signature of mussel adhesion, 3,4-Dihydroxyphenylalanine (DOPA). Recent studies have shown that adhesives in nanoparticle form offer higher adhesion on solid surfaces, making them a promising alternative. Moreover, metal ions can enhance the cohesive forces between MFPs, leading to improved adhesion. In this study, we prepared MFP nanoparticles via spray-drying and tested their adhesion performance on surfaces with varying hydrophobicity using a universal testing machine. Our findings confirmed that MFP nanoparticles exhibit stronger adhesive performance than native MFPs, with metal ions contributing to even more robust adhesion. This study offers valuable insights into the adhesive behavior of MFPs in nanoparticle form with metal ions, presenting a potential solution to the challenge of low natural production yield of MFPs and the possibility of enhancing their adhesion properties in bio-adhesive materials.
