Ahmad W, Shetab Boushehri MA, Lamprecht A. Polymeric matrix hydrophobicity governs saponin packing-density on nanoparticle surface and the subsequent biological interactions. J Colloid Interface Sci 2021; 596:500-513. [PMID: 33878541 DOI: 10.1016/j.jcis.2021.03.027] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2020] [Revised: 02/22/2021] [Accepted: 03/06/2021] [Indexed: 10/21/2022]
Abstract
This study investigated the loading behavior of Quillaja saponin as a model surface-active cargo on (NP) nanoparticles prepared with various hydrophobic polymers and using different organic solvents through emulsification/solvent evaporation, and the impact of NP surface hydrophobicity upon the cytotoxic and hemolytic properties of the loaded entity. A superficial monolayered arrangement of saponins on NP was established (R2 > 0.9) for all NP, as the saponin loading values complied with the Langmuir adsorption isotherm over the entire concentration range. Next, based on the measurement of interfacial tension between formulation phases, and the subsequent use of Gibb's adsorption isotherm, the packing density (Гexc) and loading of saponins on various nanospheres could be predicted with good correlation with the actual values (R2 > 0.95). The results demonstrated that the hydrophobicity of the polymeric matrix was the major determinant of saponin packing density on the nanospheres. Finally, the impact of NP surface properties upon saponin biological interactions was investigated, where a linear correlation was found between the NP surface hydrophobicity and their hemolytic properties (R2 ≅ 0.79), and cytotoxicity against two cancer cell lines (R2 > 0.76). The surface hydrophobicity of the polymeric NP seemingly governed the NP-cell membrane binding, which in turn determined the amount of membrane-bound saponins per unit NP surface area. As the saponins exert their cytotoxicity mainly through strong permeabilization of the cell membrane, a higher amount of NP-membrane association governed by a more hydrophobic matrix can lead to higher levels of cytotoxicity. These findings highlight the importance of a detailed characterization of NP surface properties, particularly in case of surface-active cargos, for these dictate the side effects and biological interactions of the delivery system.

Abstract
Biodegradable electronic systems represent an emerging class of technology with unique application possibilities, from temporary biomedical implants to "green" consumer gadgets. This paper introduces materials and processing methods for 3D, heterogeneously integrated devices of this type, with various functional examples in sophisticated forms of silicon-based electronics. Specifically, techniques for performing multilayer assembly by transfer printing and for fabricating layer-to-layer vias and interconnects by lithographic procedures serve as routes to biodegradable, 3D integrated circuits composed of functional building blocks formed using specialized approaches or sourced from commercial semiconductor foundries. Demonstration examples range from logic gates and analog circuits that undergo functional transformation by transience to systems that integrate multilayer resistive sensors for in situ, continuous electrical monitoring of the processes of transience. The results significantly expand the scope of engineering options for biodegradable electronics and other types of transient microsystem technologies.

Abstract
Janus particles are emerging as structurally unique drug carriers with the potential to deliver multiple drugs and agents. Although synthesis methods have been extensively explored to fabricate Janus particles, it remains a challenge to generate drug-loaded Janus particles through an economical, high throughput technique. Here, we report the formation of the first drug-loaded, micro-scale Janus particles prepared using a single-step emulsion solvent evaporation approach. Our results revealed that both the net charge of drug molecules (i.e. glibenclamide, tolbutamine, rapamycin and lidocaine) and polymer weight ratio (i.e. poly(lactic-co-glycolic) and polycaprolactone) were critical in determining the formation of Janus particles. The formation of drug-loaded Janus particles was proven to be thermodynamically-driven in accordance to the classical equilibrium spreading coefficient theory, which is strongly governed by interfacial tensions. Specifically, comparable interfacial tensions between the two interacting polymers with the water phase were identified to be key criteria to achieve the Janus particles hemispheric structure. Such interfacial tensions were amenable, and were found to be highly dependent on the interfacial charge density attributed to both drug and polymer ratio. Hereby, this study provides a mechanistic insight into the fabrication of drug-loaded Janus particles and paves an important path towards large-scale production of Janus particles using a simplified, single-step emulsion solvent evaporation strategy. Janus particles are emerging as structurally unique drug carriers with the potential to deliver multiple drugs and agents.![]()
