• groups from carboxylated CNTs. In this case, the solubility of the nanocarrier increases with an increase in pH value [24], resulting in more carboxylate anions (–COO−) produced in pH 7.4 as compared to pH 4.8. In addition, the different release mechanisms of LD at different pH levels could be also due

• therapeutic effect [26] and may benefit the treatment of PD. Release kinetics of LD To further analyse the release kinetics of LD from the SWCNT–COOH nanocarrier, pseudo-first-order (Equation 1), pseudo-second-order (Equation 2) and a parabolic diffusion equation (Equation 3) were adopted [3][27][28] as

• , R2, rate constant and half-time resulting from the pseudo-second-order model fits are also presented in Table 3. The second-order reaction suggests that the release of LD from its nanocarrier is dependent on the concentration, and that the half-time should increase as the process continues [29

• multifunctional, BNNT-based nanocarrier was synthesized using an Fe catalyst to render them magnetic and coated with PEI whereby QDs were attached to the PEI-coated BNNTs [83]. The cellular uptake of the BNNTs was tracked by QDs which revealed that the cellular uptake of the BNNTs depends upon the distance from

• micelles carrying a drug, they have been shown to be transported to and act on not only endosomes and lysosomes but also the Golgi body and mitochondria [4]. A block copolymer micelle can be used to deliver a hydrophobic drug as a nanocarrier with water-soluble biological affinity. Knowledge of the
