“…2b, and the calculated amount of PLL connected with PEG-SPIONs are about 4.4 wt%. The TGA curves still show weight loss at temperatures around 600 1C and similar results can be found in other works [15,16]. This most probably is caused by the interaction between the polymers and the nanoparticles, which increases the decomposition temperature of the polymers.…”

“…In the spectrum of ε·PL·HCl, the frequencies of the bands at 3,081, 3,246, and 3,415 cm −1 were associated with NH 2 , secondary amine and primary amine stretching vibrations, respectively. The bands at 2,868 and 2,938 cm −1 were assigned to the symmetric and asymmetric stretching vibration of CH 2 (Ling, Wei, Zou, & Xu, ). The peaks in the ranges around 1,690–1,630 and 1,590–1,480 cm −1 were related to the vibrational modes of amide Ӏ and amide II groups from l ‐lysine (Shang, Zhu, & Fan, ).…”

The objectives of this study were to characterize the physicochemical properties and evaluate the antimicrobial capacity of polyelectrolyte complexes (PECs) consisting of cationic epsilon‐polylysine·HCl (ε·PL·HCl) and anionic high‐methoxyl pectin (HMP). The physicochemical properties were analysed by microelectrophoresis (ζ‐potentials), mean diameter (Z‐average), differential scanning calorimetry (DSC) and Fourier‐transform infrared spectroscopy (FTIR). Experimental results indicated that PECs have different physicochemical properties or behaviour dependent on ε·PL·HCl/HMP mass ratio and ε·PL·HCl concentration. The antimicrobial activity was tested by minimal inhibitory concentration (MIC), which showed that the PECs had effective antimicrobial activity. Finally, this study found that using an appropriate proportion of PECs could not only avoid the formation of undesirable precipitates resulting from the interaction between ε·PL·HCl and anionic components within the soymilk systems, but also could extend their shelf‐life. Practical applications ε‐polylysine and its derivatives would interact with anionic components within foods and beverages through ionic adsorption resulting in forming undesirable precipitates, which will cause the decrease in its antimicrobial activity and the loss of food nutrients. In this study, HMP with ε·PL·HCl were used to form polyelectrolyte complexes as antimicrobial delivery systems and further reveal their physicochemical and antimicrobial properties. They could be satisfactorily applied in soymilk systems without sacrificing effective antimicrobial activity of ε·PL·HCl as well as avoiding undesirable precipitation. This information is expected to practical into protein‐containing beverage systems to extend their shelf‐life.

“…These include applications in electric circuits such as CNT-based integrated circuits (ICs), field effect transistors (FET) and solar cells [3][4][5]. In addition, CNT is an ideal candidate for potential applications in biomedical, chemical and industrial processes enabled by the use of new CNT materials [6,7].…”
