Abstract

Abstract In a nanobiotechnology world with many applications in biomedicine, a novel combination of inorganic-organic materials is needed to prove a novel functionality. Natural compounds from bee pollen extract coated on magnetite nanoparticles could open up a new way in apitherapy field. Iron oxide nanoparticles have proved special requirements for biological applications like superparamagnetic properties, high biocompatibility and nontoxic material. Magnetite nanoparticles functionalized with natural bioactive substances extracted from bee pollen have been characterised and investigated for antimicrobial activity. Previous findings demonstrate that magnetite nanoparticles (MNPs) and pollen ethanolic extracts (PEE) exhibited antimicrobial activity against a large antimicrobial spectrum, including Grampositive, Gram-negative and antifungal microorganisms.

蜂花粉提取物包被磁性纳米颗粒的抗菌活性研究
摘要纳米生物技术在生物医学领域有着广泛的应用,因此需要一种无机-有机材料的新型组合来证明一种新的功能。从蜂花粉提取物中提取的天然化合物包覆在纳米磁铁矿上,为蜂疗领域开辟了新的途径。氧化铁纳米颗粒已被证明是生物应用的特殊要求,如超顺磁性,高生物相容性和无毒材料。从蜂花粉中提取的天然生物活性物质功能化的磁铁矿纳米颗粒已经被表征并研究了其抗菌活性。先前的研究结果表明,磁铁矿纳米颗粒(MNPs)和花粉乙醇提取物(PEE)对包括革兰氏阳性、革兰氏阴性和抗真菌微生物在内的多种微生物具有抗菌活性。
