“…The immobilization kinetic data were quantitatively analyzed using the pseudo-first-order (assuming that the internal diffusion process is the rate-limiting step) and pseudo-second-order (assuming that the chemisorption of the target on active sites is the rate-limiting step) models. ,, The results and detailed data are presented in Figure B and Table . For the CSPM, the q e calculated from the pseudo-second-order model was 32.15 mg/g, which was very close to the experimental q e .…”

A novel porous chitosan macroparticle (CSPM-AG) was prepared through the escape of ammonia produced by the reaction between ammonium acetate (gas porogen) and sodium hydroxide during the solidification process of macroparticles, which was inspired by the formation of volcanic rock. The obtained several novel porous chitosan macroparticles (CSPM-AGs) were characterized by using scanning electron microscopy, nitrogen adsorption–desorption isotherms, thermogravimetric analysis, differential scanning calorimetry, and X-ray diffraction. The porosity and thermal stability of CSPM-AGs were gradually increased with the addition of gas porogen. The immobilization kinetic analysis indicated that the immobilization process belonged to the pseudo-second-order model. Also, the enzymatic characterizations of free and immobilized enzymes were investigated. The activity recovery of immobilized papain in CSPM-AGs tested by casein was significantly higher than that of the macroparticle without gas porogen (CSPM). Therefore, the novel porous macroparticles prepared via gas escape provided enough space for macromolecular substrate diffusion and a biocompatible carrier for covalent enzyme immobilization.

Hollow latex (HL) particles of polymers or hybrid polymer/inorganic materials have advantages in efficient encapsulation of active ingredients, ability to improve opacity or hiding power, and low density. Due to the flexible design for achieving the desired functionality, polymeric HL particles serve as stimuli-responsive capsules for drug delivery and cosmetics, white pigment for coatings, as well as nanoreactors for the confined reactions. Among numerous studies on the synthesis of HL particles for specific applications, this review article summarizes the recent works on the HL particles prepared from both synthetic and natural polymers. The template-based methods using sacrificial hard or soft template, self-templating, and nonsacrificial techniques are described. Various factors affecting morphologies and properties of HL particles are discussed in detail. Their applications in coatings, cosmetics, biomedicines, electronics, and others are also presented.
