Background: As an emerging carbon nanomaterial, Graphene Quantum Dots (GQDs) have shown great potential application in new energy storage devices due to their unique small size effect and abundant edge active sites. This work introduces the main synthesis strategies of GQDs, which include top-down and bottom-up methods; the application examples of GQDs and GQDsbased composites in energy storage are reviewe Read More

Background: In dermatology, the topical application of liposomes has proven to be of therapeutic value. Many drugs encapsulated into liposomes have shown enhanced skin penetration. Methods: Liposomes are lipid based spherical vesicles. In structure and composition, they resemble cell membrane. Because of their amphipathic nature, they can be used as carriers for hydrophilic as well as lipophilic therapeutic agents. Th Read More

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is one of the seven known coronaviruses infecting humans; HKU1, 229E, NL63, OC43, Acute Respiratory Syndrome Coronavirus (SARS-CoV), Middle East Respiratory Syndrome Coronavirus (MERS-CoV), and SARS-CoV-2, the last three of which can cause severe symptoms in patients. COVID-19, previously known as 2019 novel coronavirus, caused by SARS-CoV-2, Read More

Background: Acne is one of the most infectious diseases related to human skin. This disease of acne is of higher prevalence in adults. The main causative organism involved in the acne vulgaris is Propionibacterium acne, which leads to sebum production and follicular hyperkeratinization. Methods: The scientific data shows inflammatory mediators of genetic factors, stress, physiological factor, androgens and hormonal cha Read More

Background: Nanosuspensions are colloidal systems consisting of pure drug and stabilizers, without matrix or lyophilized into a solid matrix. Nanosuspensions improve the solubility of the drug both in the aqueous and organic phases. Nanosuspensions are also known as brick dust molecules, as they increase the dissolution of a system and improve absorption. Methods: Extensive information related to nanosuspens Read More

Background: Cancer is caused by mutations in oncogenes and loss of tumor suppressor activity. Despite the efforts of the pharmaceutical industry to fight cancer, it is necessary to investigate new methods to enhance the action against this disease. In this scenario, liposome technology has emerged as a drug delivery system for cancer treatment. The objective of this study was to evaluate the use of liposome technology in t Read More
