Background and Objective: Bio-soft material, a class of derivatives of the natural or synthetic material, is getting more and more prevalent in biomedical researches and applications due to the advantages such as in-vivo biodegradation, good water solubility and designable targeting ability. With the presence of bio-soft materials, the drug nanocrystal can be easily generated and aggregated in a feasible process. Given the p Read More

Background: Nanocrystallization technologies have been widely studied in recent years, as the formulation of drug nanocrystals solves problems of poor drug solubility and bioavailability. However, drug nanocrystals in the size range of 1–1000 nm usually need to be accompanied by stabilizers, such as polymers or surfactants, to enhance their stability. Despite their simplicity, improved dissolution rate, and enhanced bioavailabili Read More

Background: Nowadays, the polymorphism of solid materials plays important roles in pharmaceutical field, food industry, fine chemicals and so on. Due to the differences in crystal structure, different polymorphs of a given solid drug show different physicochemical characteristics, which may lead to different drug bioavailability and half-life of the drug. Studies about polymorphism of solid drugs have become an indispensable i Read More

Polymorphism is a behavior of a substance to crystallize into more than one district crystal structures. Preferential formation of a polymorph depends strongly on the kinetics of the relevant mechanisms. Solutionmediated polymorphic transformation is an important mechanism in crystallization of organic compounds from solution. Knowing its kinetics allows us to understand the process and control the polymorphic Read More

These techniques may increase effective surface area due t Read More

Background and Objective: Nanocrystal technology is an effective approach which can increase the dissolution rate of poorly water-soluble drugs by raising their saturation solubility, thus improving the drug bioavailability. With the development of nanocrystals, its preparation approaches have gradually matured, which can be generally divided into Bottom-up, Top-down and Combinative technologies. Methods: A systematic liter Read More

Crystallization is a significant process employed to produce a wide variety of materials in pharmaceutical and food area. The control of crystal dimension, crystallinity, and shape is very important because they will affect the subsequent filtration, drying and grinding performance as well as the physical and chemical properties of the material. This review summarizes the special features of crystallization technology and the p Read More

Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide, leading to the second most likely cause of cancer-related deaths. Medical imaging is crucial in clinic for HCC screening and diagnosis. Due to the relatively high special resolution and excellent sensitivity, magnetic resonance imaging (MRI) by using magnetic nanoparticle-based contrast agents has been used so far in HCC imaging and staging, demo Read More

Background and objective: Pulmonary drug delivery has transformed over a past few decades from being a platform for local pulmonary disease treatment to systemic drug delivery opportunities. In case of pulmonary delivery systems, particle properties are critical as they affect inhalation efficacy, pulmonary deposition, drug delivery and overall performance. With this in view, particle engineering has emerged as an advan Read More

Background: Pharmaceutical industry is witnessing increased pressure to introduce innovative and efficient processes for manufacturing Active Pharmaceutical Ingredients (APIs) in order to be competitive as well as to meet the stringent product quality requirements set by regulatory authorities. Crystallization with its ability to engineer the final product to the desired qualities such as purity, polymorphic form, particle s Read More

Background: Crystal engineering is dealing with the creation of new structures and new properties in drug molecules through inter-molecular interactions. Researchers of pharmaceutical sciences have used this knowledge to alter the structure of crystalline medications in order to remedy the problems of more than 40% of the new designed drugs which suffer from low solubility and consequently, low bioavailability which h Read More

Fats are essential nutrients that have a significant role in the human diet and are essential to provide energy. Fatty acids are present in several types of lipids, such as triglycerides and phospholipids. Fatty acids differ among them, depending on the number of double bonds and on the length of the hydrocarbon chains. If there are no double bonds, the fatty acids are considered saturated and show a linear structure. Compoun Read More
