Adra HJ, Ryu HB, Jo AH, Lee JH, Choi SJ, Kim YR. Ligand-based magnetic extraction and safety assessment of zinc oxide nanoparticles in food products. JOURNAL OF HAZARDOUS MATERIALS 2024; 465:133235. [PMID: 38141311 DOI: 10.1016/j.jhazmat.2023.133235] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Revised: 11/27/2023] [Accepted: 12/10/2023] [Indexed: 12/25/2023]
Abstract
Zinc oxide (ZnO) is a zinc supplement widely used in health products and is approved by the FDA as Generally Regarded as Safe (GRAS). However, concerns have arisen regarding the potential health effects of nanoscale ZnO, as its reactivity differs from that of its bulk form. This has led to the need for an efficient method to extract ZnO from food products without altering its physicochemical properties, where conventional methods have proven to be inadequate. This study introduces an innovative approach using starch magnetic particles (SMPs) functionalized with a 12-amino acid peptide modified with five lysines (ZBP), that has specific affinity to ZnO. ZBP@SMPs effectively and rapidly extract intact ZnO from food products, achieving recovery efficiencies ranging from 60% to 90%, all while maintaining its morphology and crystallinity. The diameter of ZnO particles recovered from six commercial food products ranged from 25 to 500 nm, with 33% falling below 100 nm, highlighting the need for a size-dependent toxicity study. However, cytotoxicity assessment on human intestinal Caco-2 cells shows all ZnO samples affects cell proliferation and membrane integrity in a dose-dependent manner due to partial dissolution. This study contributes to understanding the safety of ZnO-containing food products and highlights potential health implications associated with their consumption.

Abstract
Metallo-oxide (MO)-based bioinorganic nanocomposites promise unique structures, physicochemical properties, and novel biochemical functionalities, and within the past decade, investment in research on materials such as ZnO, TiO2, SiO2, and GeO2 has significantly increased. Besides traditional approaches, the synthesis, shaping, structural patterning, and postprocessing chemical functionalization of the materials surface is inspired by strategies which mimic processes in nature. Would such materials deliver new technologies? Answering this question requires the merging of historical knowledge and current research from different fields of science. Practically, we need an effective defragmentation of the research area. From our perspective, the superficial accounting of material properties, chemistry of the surfaces, and the behavior of biomolecules next to such surfaces is a problem. This is particularly of concern when we wish to bridge between technologies in vitro and biotechnologies in vivo. Further, besides the potential practical technological efficiency and advantages such materials might exhibit, we have to consider the wider long-term implications of material stability and toxicity. In this contribution, we present a critical review of recent advances in the chemistry and engineering of MO-based biocomposites, highlighting the role of interactions at the interface and the techniques by which these can be studied. At the end of the article, we outline the challenges which hamper progress in research and extrapolate to developing and promising directions including additive manufacturing and synthetic biology that could benefit from molecular level understanding of interactions occurring between inanimate (abiotic) and living (biotic) materials.

Abstract
Enzymes are some of the most efficient catalysts in nature. If small catalytic peptides mimic enzymes, there is potential for broad applications from catalysis for new material synthesis to drug development, due to the ease of molecular design. Recently a hydrogel-based combinatory phage display library was developed and protease-mimicking peptides were identified. Here we advanced the previous discovery to apply one of these catalytic peptides for the synthesis of bimetal oxide nanocrystals through the catalytic ester-elimination pathway. Conventional bimetal oxide crystallization usually requires high temperatures above several hundred °C; however, this catalytic peptide could grow superparamagnetic MnFe2O4 nanocrystals at 4°C. Superconducting quantum interference device (SQUID) analysis revealed that MnFe2O4 nano-crystals grown by the catalytic peptide exhibit superpara-magnetism. This study demonstrates the usefulness of protease-mimicking catalytic peptides in the field of material synthesis.
