“…The observed adsorptiondesorption isotherm demonstrated a distinctive blend of Type-I and Type-IV behavior. Specifically, a rapid increase in adsorption at very low relative pressure levels (P/P0 < 0.01) pointed to the presence of supermicropores (pores smaller than 4 nm) and mesopores, evident from the H4 hysteresis [37]. The determination of the surface area disclosed a significant value of 35.726 m 2 g −1 , accompanied by a measured pore volume of 0.053 cm 3 g −1 .…”

Albumin is a vital blood protein responsible for transporting metabolites and drugs throughout the body and serves as a potential biomarker for various medical conditions, including inflammatory, cardiovascular, and renal issues. This report details the fabrication of Ni-metal organic framework/SnS2 nanocomposite modified nickel foam electrochemical sensor for highly sensitive and selective non enzymatic detection of albumin in simulated human blood serum samples. Ni-metal organic framework/SnS2 nanocomposite was synthesized using solvothermal technique by combining Ni-MOF with conductive SnS2 leading to the formation of a highly porous material with reduced toxicity and excellent electrical conductivity. Detailed surface morphology and chemical bonding of the Ni-MOF/SnS2 nanocomposite was studied using scanning electron microscopy (SEM), transmission electron microscopy (TEM), FTIR, and Raman analysis. The Ni-MOF/SnS2 nanocomposite coated on Ni foam electrode demonstrated outstanding electrochemical performance, with a low limit of detection (0.44 µM) and high sensitivity (1.3 µA/pM/cm2) throughout a broad linear range (100 pM - 10 mM). The remarkable sensor performance is achieved through the synthesis of a Ni-MOF/SnS2 nanocomposite, enhancing electrocatalytic activity for efficient albumin redox reactions. The enhanced performance can be attributed due to the structural porosity of nickel foam and Ni-metal organic framework, which favours increased surface area for albumin interaction. The presence of SnS2 shows stability in acidic and neutral solutions due to high surface to volume ratio which in turn improves sensitivity of the sensing material. The sensor exhibited commendable selectivity, maintaining its performance even when exposed to potential interfering substances like glucose, ascorbic acid, K+, Na+, uric acid, and urea. The sensor effectively demonstrates its accuracy in detecting albumin in real samples, showcasing substantial recovery percentages of 105.1%, 110.28%, and 91.16%.

In recent years, MOFs hydrogels have attracted extensive attention due to their unique structure and excellent performance. MOF‐based hydrogels combine the highly ordered pore structure and tunability of MOF with the biocompatibility and flexibility of hydrogels, and are widely used in environmental governance, sensors, and biomedicine. In this review, we mainly summarize the synthesis methods, structural characteristics and mechanical properties of MOF‐based hydrogels, and the specific applications of MOF‐based hydrogels in different fields including adsorption of heavy metal ions and pollutant gases stress strain sensor and drug delivery. Finally, we analyze the existing problems, and provide suggestions for the development direction of MOF‐based hydrogels in the future. This paper aims to help readers quickly understand the current development of MOF‐based hydrogels.
