碳酸钙的仿生矿化 Title:BiomimeticMineralizationofCalciumCarbonate Introduction: Calciumcarbonate(CaCO3)isanessentialmineralfoundinvariousnaturalforms,suchaslimestone,chalk,andmarble.Duetoitsuniquepropertiesandwidespreadapplications,includingbuildingmaterials,pharmaceuticals,andenvironmentalremediation,thesynthesisandunderstandingofcalciumcarbonate-basedmaterialshavegainedsignificantattention.Biomimeticmineralization,inspiredbynature'sabilitytocontrolmineralformation,hasemergedasapromisingapproachtodesignandsynthesizecalciumcarbonatewithimprovedpropertiesandfunctionalities.Thispaperaimstoexploretheprinciplesandapplicationsofbiomimeticmineralizationinthesynthesisofcalciumcarbonate-basedmaterials. PrinciplesofBiomimeticMineralization: Natureprovidesnumerousexamplesofbiomineralizationprocesseswherelivingorganismscontrolandguidetheformationofminerals.Byunderstandingandemulatingtheseprocesses,researchershavesoughttomimicnature'sstrategiesforcalciumcarbonatemineralization.Biomimeticmineralizationgenerallyinvolvestheuseoforganicmolecules,suchasproteins,peptides,andpolysaccharides,astemplatingagentstocontrolthenucleation,growth,andmorphologyofcalciumcarbonatecrystals.Bymimickingtheorganicmatrixfoundinnaturalsystems,biomimeticapproachescanproducematerialswithenhancedmechanicalstrength,controlledcrystalorientation,andtailoredfunctionalities.
