Due to its excellent characteristics, zeolitic imidazole framework-L (ZIF-L) is widely used in various applications, such as drug delivery, wastewater treatments and energy storage. In the synthesis of ZIF-L, the molar ratio of ligand to metal, the reaction time and the temperature are essential parameters to produce excellent ZIF-L. In this work, ZIF-L was synthesized using a facile and green synthesis method. It was statistically investigated and optimized to obtain the best operating conditions. The optimization was carried out toward the amount of adsorbed crystal violet (CV) dye (q) as the response in the statistics. The optimal ZIF-L was obtained using a molar ratio of ligand to metal of 8.2220 for 97 min at 29 °C, where the q value of the CV adsorption onto this optimal ZIF-L reached 823.02 mg/g. The obtained ZIF-L was characterized using SEM, XRD, FTIR and TGA analyses to ensure its excellent characteristics.

“…Recent studies more developed the modification or functionalization of CNCs for enhancing the ability as a drug carrier. Several compounds have been used to modify the surface of CNCs, such as surfactants, small molecule compounds, oils, and polymers [ 70 ]. The main aim of surface modification is to change the characteristics of CNCs, especially from hydrophilic to hydrophobic CNCs.…”

“…However, the selection of modifying agents is needed to be considered carefully in case of health and environmental issues. As an example, rarasaponins was chosen as a modifying agent for CNCs due to its safety for health and environment, where it is biodegradable and non-toxic surfactant from natural resources [ 70 , 71 ].…”

“…These functional groups supported the bindings of the hydrophilic drug onto modified CNCs. As described in Table 5, various investigations of CNCs modifications have been done and applied for many hydrophobic drugs, such as paclitaxel [66,72], docetaxel, etoposide [66], luteolin, luteoloside [69], curcumin [70,73,74], and tosufloxacin tosylate [65]. Putro et al [72] studied the effects of CNCs modifications using cationic, anionic, and nonionic surfactants in hydrophobic drug delivery.…”

Due to their biocompatibility, biodegradability, and non-toxicity, lignocellulosic-derived nanoparticles are very potential materials for drug carriers in drug delivery applications. There are three main lignocellulosic-derived nanoparticles discussed in this review. First, lignin nanoparticles (LNPs) are an amphiphilic nanoparticle which has versatile interactions toward hydrophilic or hydrophobic drugs. The synthesis methods of LNPs play an important role in this amphiphilic characteristic. Second, xylan nanoparticles (XNPs) are a hemicellulose-derived nanoparticle, where additional pretreatment is needed to obtain a high purity xylan before the synthesis of XNPs. This process is quite long and challenging, but XNPs have a lot of potential as a drug carrier due to their stronger interactions with various drugs. Third, cellulose nanocrystals (CNCs) are a widely exploited nanoparticle, especially in drug delivery applications. CNCs have low cytotoxicity, therefore they are suitable for use as a drug carrier. The research possibilities for these three nanoparticles are still wide and there is potential in drug delivery applications, especially for enhancing their characteristics with further surface modifications adjusted to the drugs.

“…The surface modification of CNCs can not only retain the original properties of CNCs, but also give new surface properties, such as hydrophobic [ 53 , 54 ], biocompatibility [ 55 ], antistatic properties [ 56 , 57 ], and dyeing properties [ 58 ]. The surface of the CNCs contains numerous hydroxyl (–OH) groups, which provide the main reaction site for modification.…”

Nanocellulose, typically cellulose nanocrystals (CNCs), has excellent properties and is widely used. In particular, CNC has a small dimension, high chemical reactivity, and high sustainability, which makes it an excellent candidate as a starting material to be converted into nanocellulose derivatives. Chemical modification is essential for obtaining the desired products; the modifications create different functional attachment levels and generate novel microstructures. Recent advances on nanocellulose derivatives have not yet been reviewed and evaluated for the last five years. Nanocellulose derivative materials are being used in a wide variety of high-quality functional applications. To meet these requirements, it is essential for researchers to fully understand CNCs and derivative materials, precisely their characteristics, synthesis methods, and chemical modification approaches. This paper discusses CNC and its derivatives concerning the structural characteristics, performance, and synthesis methods, comparing the pros and cons of these chemical modification approaches reported in recent years. This review also discusses the critical physicochemical properties of CNC derivative products, including solubility, wetting performance, and associated impacts on properties. Lastly, this paper also comments on the bottlenecks of nanocellulose derivatives in various applications and briefly discusses their future research direction.
