AB  - Metal-organic frameworks (MOFs) are a class of inorganic materials with potential application in gas adsorption, biosensitization, biocatalysis, and drug delivery [1]. Zeolitic imidazolate frame-works (ZIFs) are a subclass of MOFs, particularly suitable for enzyme immobilization by biomi-metic mineralization [1]. ZIF-8 consisting of tetrahedral Zn(II) ions bridged via 2-methylimidazole ligands (mIM) is most commonly used for this purpose. However, the topology and morphology of ZIF-8 crystals vary depending on the experimental synthesis conditions. In addition, during the process of biomimetic mineralization, the biocomposite composed of the enzyme immobilized in ZIF-8 is washed with buffers and detergents to remove excess of an adsorbed enzyme, which can lead to the chemical transformation of the surface and undesirable release of the enzyme. There-fore, the influence of anion nature on the topology and morphology of ZIF-8 was investigated in this work, and the stability of ZIF-8 crystallites was tested in acetate buffer (0.1 M; pH = 5.5) and sodium dodecyl sulfate solution (ω = 10%). Crystal morphology was monitored by scanning elec-tron microscopy, while topology was determined using powder X-ray diffraction.

AB  - Metal-organske umrežene strukture (MOF-ovi) su klasa neorganskih materijala sa potencijalnom primenom u adsorpciji gasova, biosenzibilizaciji, biokatalizi i isporuci lekova. Zeolitske imidazolske umrežene strukture (ZIF-ovi) su potklasa MOF-ova posebno pogodna za imobilizaciju enzima metodom biomimetičke mineralizacije. U ovu svrhu se najčešće koristi ZIF-8 koji se sastoji tetraedarskih jona Zn(II) povezanih preko mostnih 2-metilimidazolskih liganada. MeĎutim, topologija i morfologija kristala ZIF-8 varira u zavisnosti od eksperimentalnih uslova sinteze. TakoĎe, tokom procesa biomimetičke mineralizacije, biokompozit sastavljen od enzima imobilizovanog u ZIF-8 se ispira puferima i detergentima radi uklanjanja viška adsorbovanog enzima, pri čemu može doći do hemijske transformacije površine i nepoželjnog otpuštanja enzima. Stoga je u ovom radu ispitivan uticaj prirode anjona na topologiju i morfologiju ZIF-8, a stabilnost kristalita ZIF-8 je testirana u acetatnom puferu i rastvoru natrijum-dodecilsulfata. Morfologija kristala je praćena skenirajućom elektronskom mikroskopijom, dok je topologija odreĎena primenom difrakcije X-zraka na uzorku praha.
