“…However, no in vivo study was performed to ascertain the efficacy of the riboflavin-conjugated MWCNTs in poly(ester-imide) matrix. Mallakpour et al [ 53 ] synthesized ascorbic acid-modified MWCNTs by polymer modifications using poly(amide-imide) ( Figure 6 b). The free hydroxyl group of ascorbic acid reacted with the free carboxylic group of poly(amide-imide) to form a covalent ester bond following microwave irradiation.…”

“…This microwave-modified method increased the attachment, dispersibility, and interaction of MWCNTs with ascorbic acid, compared to unmodified poly(amide-imide) MWCNTs, indicating that the polymer increases the attachment of ascorbic acid. The surface modification of carboxylated MWCNTs was conducted with ascorbic acid ( Figure 6 c), using a microwave-assisted method (700 W for 15 min at 120 °C), followed by polyester-imide ultrasonication with polyester-imide for 1 h [ 53 ]. The covalent interactions, dispersibility, and thermal activity of the ascorbic acid-modified MWCNTs were increased, compared to unmodified CNTs.…”

Microwave-assisted synthetic methods have emerged as a popular technique for surface modification and the functionalization of multi-walled carbon nanotubes (MWCNTs) for diverse drug delivery applications. Microwave-induced functionalization of MWCNTs provides a high functionalization and requires less time than conventional techniques. Microwave methods are simple, fast, and effective for the covalent and noncovalent conjugation of MWCNTs with various biomolecules and polymers. The present review focuses on the synthetic and drug delivery applications of microwave irradiation techniques (MITs) for the functionalization of MWCNTs, using amino acids and other molecular frameworks containing amino groups, vitamins, proteins, epoxy moieties, metal nanoparticles, and polymers.

“…Polyester is the most concerned material in the field of degradation, such as polylactide (PLA), while its brittleness and poor heat resistance limit its development [ 15 , 16 ]. Polyester-imides (PEIs) obtained by incorporating imide bond and ester bond into the polymer concurrently can overcome their shortcomings, and the introduction of amino acids improves its biocompatibility [ 17 , 18 , 19 ].…”

Eight kinds of chiral diacid monomers were prepared with amino acids with different side groups or configurations. Polyester-imides (PEIs) were synthesized from these diacid monomers and diphenol monomers through polycondensation reaction, and the performances and properties were compared with the chiral polyamide-imides (PAIs) previously synthesized by our work group. Their thermal properties were analyzed by thermo gravimetric analysis (TGA) and dynamic thermomechanical analysis (DMA), and it was found that the glass transition temperature (Tg) of PEI was mainly affected by the volume of side groups. Their degradability was studied through buffer degradation experiments, and the changes in their water contact angle, molecular weight, structure and appearance during the degradation process were characterized by contact angle tester, gel permeation chromatography (GPC), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). With degradation, the hydrophilicity of PEI was improved, and when amino acids with larger side groups or D configuration were introduced into the backbone of PEI, the degradability decreased.
