天然矿物质(“石药”)在传统中药中使用已有2000多年的历史,但在现代,无机矿物质有可能用于对抗病毒感染、抗微生物药物耐药性以及需要新疗法和诊断辅助的其他领域。从毫米到纳米尺度的金属和矿物表面,无论是天然的还是合成的,都可以用亲水性/疏水性和离子/共价目标识别位点进行图案修饰或修饰。他们为医学应用引入了新的策略。与单金属中心相比,这种表面具有新颖的特性。此外,三维矿物颗粒(包括混合有机矿物)可以具有反应腔,一些矿物在其结构内具有金属离子、阴离子和其他分子的动态运动。矿物具有通过多点离子和/或非共价接触与病毒、微生物和大分子相互作用的独特能力,在治疗和生物技术方面具有新的应用潜力。生物学中矿藏的研究往往具有固有的异质性,并且在分离后往往会发生化学修饰,这是极具挑战性的,但研究它们的新方法,包括在完整组织中的研究,有望在未来取得进展。矿物质在生物学中发挥着重要的天然作用,并在设计新药、诊断疾病以及通过生物分子的多位点识别发现新的生物技术应用方面提供了相对未开发的潜力。
Natural minerals (‘stone drugs’) have been used in traditional Chinese medicines for over 2000 years, but there is potential for modern-day use of inorganic minerals to combat viral infections, antimicrobial resistance, and for other areas in need of new therapies and diagnostic aids. Metal and mineral surfaces on scales from milli-to nanometres, either natural or synthetic, are patterned or can be modified with hydrophilic/hydrophobic and ionic/covalent target-recognition sites. They introduce new strategies for medical applications. Such surfaces have novel properties compared to single metal centres. Moreover, 3D mineral particles (including hybrid organo-minerals) can have reactive cavities, and some minerals have dynamic movement of metal ions, anions, and other molecules within their structures. Minerals have a unique ability to interact with viruses, microbes and macro-biomolecules through multipoint ionic and/or non-covalent contacts, with potential for novel applications in therapy and biotechnology. Investigations of mineral deposits in biology, with their often inherent heterogeneity and tendency to become chemically-modified on isolation, are highly challenging, but new methods for their study, including in intact tissues, hold promise for future advances. Minerals play important natural roles in biology and offer relatively unexplored potential for the design of novel drugs, for the diagnosis of disease, and for discovery of new biotechnological applications via multisite recognition of biomolecules.
