“…[15][16][17] When the micropore channel was closed, subsequent drug release could only take place slowly by diffusion through the skeleton, or through the degradation of chitosan. [18][19][20] After 240 minutes, the cumulative release rate decreased, possibly due to the instability and accelerated degradation of salvianolic acid. However, release conditions in vitro are quite different from those in vivo; further in vivo experiments are therefore necessary.…”

Objective: This study aims to investigate the preparation of sustained-release microcapsules of salvianolic acid. Methods: The stability of salvianolic acid microcapsules was improved, and the time of action was prolonged in the present study. This was prepared using the spray-drying method, with chitosan as the carrier. In the preparation process, the prescription and process were optimized by L9 (34) using an orthogonal design, with yield and drug loading as indexes, in order to obtain optimum conditions. Results: The optimal process and prescription for the preparation of salvianolic acid microcapsules were found to be as follows: mass concentration of chitosan, 1.5%; mass ratio of salvianolic acid to chitosan, 1:3; inlet air temperature, 190°C; and peristaltic pump speed, 300 mL•h-1. The surface of the microcapsules was round, the drug loading was 25.99% ± 2.14%, the yield was 51.88% ± 2.84%, the entrapment efficiency was 86.21% ± 2.89%, and the average particle size was 105.6 ± 2.56 nm. The microcapsules in vitro had certain sustained release characteristics. The internally fitted first-order release model equation was ln(1-Q) = −0.236 t + 4.591 7, r = 0.920. In addition, the results of differential scanning calorimetry show that the properties of salvianolic acid were not changed by the microcapsules. Conclusion: Sustained-release microcapsules of salvianolic acid can be successfully prepared by adopting marine polysaccharide as a carrier.

“…Higher equilibrium adsorption capacities was achieved with the hydrogen bonding formation between the MOF and the pollutants [230]. Luo et al (2019) reported on the enhanced removal of bisphenol A using Al-based composite Al-MOF/SA-CS. The adsorption capacity was 136 mg/g.…”

“…The adsorption capacity was 136 mg/g. The adsorption mechanism has been explained by the formation of hydrogen bonding, π-π stacking and cation-π interactions [231]. Adsorptions of phenolic compounds onto MOFs have also been studied.…”

“…Among the various polymers, chitosan (CS) stands out, since it acts not only as a continuous phase or support but also as an adsorption adjuvant in hybridizations. The resulting biocomposites would have the merits of high porosity, excellent adsorption ability, and reusability, which are very beneficial for the enrichment of trace targets in aqueous samples [ 81 , 82 , 83 ]. Thus, Li et al [ 81 ] developed a variety of highly porous MOF/CS foams as sorbents for the extraction of parabens in water samples.…”

This review summarizes the recent advances concerning metal–organic frameworks (MOFs) modified with several biomolecules (e.g., amino acids, nucleobases, proteins, antibodies, aptamers, etc.) as ligands to prepare affinity-based sorbents for application in the sample preparation field. The preparation and incorporation strategies of these MOF-based affinity materials were described. Additionally, the different types of ligands that can be employed for the synthesis of these biocomposites and their application as sorbents for the selective extraction of molecules and clean-up of complex real samples is reported. The most important features of the developed biocomposites will be discussed throughout the text in different sections, and several examples will be also commented on in detail.
