Abstract

Thermoprecipitating polymers such as poly (N-isopropylacrylamide), poly(N-vinyl caprolactam), and some ethylene oxide-containing surfactants appear to be suitable for developing new separation systems to complement traditional precipitation, chromatography, and extraction of biological molecules. The nature of thermally induced phase separation of polymers and nonionic surfactants is discussed and examples are given. Covalent coupling of an enzyme to a thermoprecipitable polymer results in a biocatalyst which combines the qualities of soluble and immobilized enzymes. Biocatalysts of this type can be separated from reaction media by precipitation after temperature increase. The use of thermopreciptating polymer-protein conjugates in immunoassays overcomes one of the shortcomings of traditional methods with solid sorbent-linked antigen or antibody-diffusional limitations. Thermore-active hydrogels produced by crosslinking of thermoprecipitating polymers can be successfully used for concentrating macromolecules or microbe-rich slurries. Alternate volume changes of hydrogels on heating and cooling produce a “hydraulic pump” which can enhance the productivity of an immobilized biocatalyst. Hydrogels could be used to control reaction of diffusion rates by a thermal feedback mechanism.

A scalable biomanufacturing platform for bacterial magnetosomes
2024, Food and Bioproducts Processing
An integrated scalable platform for fermentative production and downstream processing of bacterial magnetosome products is advanced. Long magnetosome chains, high cellular magnetism, and low numbers of polyhydroxyalkanoate granules were obtained during the exponential growth phase of a two-stage continuous high cell density fermentation of M. gryphiswaldense MSR-1. Centrifugally concentrated 20% (w/v) suspensions of exponential phase cells were disrupted with high efficiency (∼92%) in a single pass through a Constant Systems Cell Disruptor operated at 10 kpsi, releasing ∼75% of the cellular iron. Magnetosomes were recovered in partially purified form from crude whole cell disruptates by rotor-stator high-gradient magnetic separation. Further purification/polishing was achieved by magnetically enhanced density separation in an aqueous micellar two-phase system (a new technique developed in this work as a low-cost alternative to sucrose gradient ultracentrifugation). The unoptimised 4-step process delivered highly purified magnetosomes (ca. 50 and 80-fold with respect to polyhydroxyalkanoate and protein) in > 50% yield, with no evidence of crystal coat damage, acceptable reduction (∼35%) in median magnetosome chain length, and magnetic properties (pot-bellied hysteresis loop, coercivity = 9.8 mT, ‘squareness’ = 0.32) expected of isolated magnetosome chains. Though demonstrated in batch mode, the platform displays potential for end-to-end continuous manufacture of future magnetosome-based products.
Supercritical drying of thermoresponsive gels based on N-isopropylacrylamide
2020, Journal of the Taiwan Institute of Chemical Engineers
Citation Excerpt :
For an aqueous colloidal solution of polymers above their UCST or below their LCST the polymer and the solvent are enthalpically driven to preferentially associate with themselves, thus solvation fails and the polymer collapses. The underlying process of contraction of the polymer as the solvation decreases by heating has been reported for many polymers [7], and among them, N-isopropyl acrylamide (NIPAM) polymers and copolymers [8] are probably the most investigated ones because they have a LCST close to body temperature and almost independent of molecular weight and concentration, and they also show adequate biocompatibility [9]. The crosslinking degree and bonding density between the polymeric chains have great influence on the final properties of the gels.
Thermoresponsive materials are of great interest for medicine, pharmacy and food industry. During the production of these materials they are often taken into their dry state, requiring gentle processes with minimum effect over their properties. In this study, supercritical drying process was used to obtain dry products from thermoresponsive N-Isopropylacrylamide based gels and compared to other typical drying processes like hot air- and freeze- drying. Depending on the method, different degrees of modification of the structure were observed, which have a significant influence on the final properties of the materials and on their rehydration. Results show that supercritical technology can be used to produce dry porous materials with less collapsed structure or modified properties than conventional or freeze drying techniques while keeping the thermoresponsive nature, which is translated into materials with higher porosity and surface area, and slightly improved swelling degree. Swelling kinetics results showed that materials dried by conventional drying displayed sigmoidal anomalous behavior, those dried by freeze-drying exhibited a two-stage anomalous behavior, and materials obtained by supercritical drying presented behaviors close to Fickian which is of great interest for further drug release applications.
Stimuli-sensitive drug delivery systems
2020, Nanoengineered Biomaterials for Advanced Drug Delivery
In recent years, there have been significant impacts on biomedical science by advances in materials science. Concepts such as nanotechnology have a great impact on biomedical science. Various drug carriers have been scaled down to nanoscales to improve the efficiencies of the systems. The approaches in synthesizing new nanocarriers tend to prepare personalized nanomedicines with regard to abnormal conditions of the patients such as in pathological areas including tumors. It is well known that different cancers show abnormal conditions such as changes in pH, temperature, and redox concentration. Therefore the concept of stimuli-sensitive drug delivery systems was established toward the development of personalized nanomedicines. These delivery systems are sensitive to the patient’s abnormal conditions and respond to these condition through physicochemical changes in their structure. This chapter will provide the readers with an overview of stimuli-sensitive drug delivery systems utilizing micro- and nanocarriers with a focus on cancer therapy.
Radiation-grafting of N-vinylcaprolactam and 2-hydroxyethyl methacrylate onto polypropylene films to obtain a thermo-responsive drug delivery system
2019, Radiation Physics and Chemistry
2-Hydroxyethyl methacrylate (HEMA) and N-vinylcaprolactam (NVCL) were grafted onto polypropylene films (PP) by radiation-induced grafting, using gamma-radiation (from a ⁶⁰Co gamma source) with the aim of improving their surface properties and endow the films with the ability to act as drug-eluting materials. Different γ-radiation doses, reaction temperatures, and monomer concentrations were tested to understand the effect that each variable had on the grafting yield of each compound in separate, and to identify the optimum grafting conditions. The PP films were grafted using the pre-irradiation oxidative method, in a one- and two-step procedure, to obtain binary grafts of various architectures, namely (PP-g-HEMA)-g-NVCL, (PP-g-NVCL)-g-HEMA, and PP-g-(HEMA-co-NVCL). The untreated and modified PP films were characterized by infrared spectroscopy (FTIR-ATR), thermal analyses (DSC and TGA), swelling degree, and contact angle measurements. The temperature responsiveness of the films was evaluated through changes induced at the lower critical solution temperature (LCST), which allowed the material to load and release benzalkonium chloride and ciprofloxacin.
Malic acid extraction from aqueous solution by using aqueous two-phase system method
2019, Results in Chemistry
In this investigation malic acid extraction by aqueous two-phase system method (ATPS) was performed. ATPS are involved polymer (PEG 4000 and 8000) and various phosphate salts. Effect of PEG molecular weight, pH, temperature and concentration of salt were studied as independent parameters and the partition coefficient (D) and percentage of extraction(Y %) were considered as responses of the system. In order to the results, increasing all of the independent parameters cause to decrease the partition coefficient and percentage of extraction. As these parameters decrease, malic acid tends to move in the top phase (PEG-rich phase), and consequently separation will be occurred properly. In addition, van't Hoff equation was applied for discussing temperature effect on malic acid extraction. The obtained results show that increasing of temperature cause to increasing in Gibbs free energy. The best operation condition for malic acid extraction was obtained 4000, 25% w/w, 293 K and 5 for PEG molecular weight, Salt concentration, Temperature and pH, respectively.
