AbstractNanoemulsions are nano-sized particles, typically ranging from tens to hundreds of nanometers. These nanoemulsions possess various appealing properties, making them highly promising for various applications in pharmaceutics, foods, and cosmetics. These properties include their small size, which allows for a high surface area per unit volume, and their ability to disperse hydrophobic components and enhance absorption effectively. In the pharmaceutical industry, nanoemulsions have been developed to enhance the delivery of hydrophobic active ingredients. Macromolecular surfactants offer enhanced emulsion stability compared to conventional low-molecular surfactants. Enhanced stability is due to their slower desorption kinetics at the droplet interface, which reduces the risk of toxicity and skin irritation associated with the latter. This article presents a comprehensive investigation into the role of nanoemulsions in drug delivery. It commences by delineating various emulsion types and subsequently explores techniques for nanoemulsion preparation. Surfactants serve as pivotal components in both the production and stabilization of nanoemulsions. The review provides an encompassing overview of diverse surfactant types, encompassing small molecule variants, particle surfactants, phospholipids, peptides, and protein-based surfactants tailored for nanoemulsions. Additionally, it addresses nanoemulsion instability, elucidating strategies to mitigate instability challenges, and highlights the utilization of nanoemulsions in nanomedicine for effective drug delivery. This comprehensive overview aims to offer insights for researchers engaged in nanoemulsion-related studies and associated interdisciplinary fields. [ABSTRACT FROM AUTHOR]

Diabetes is a chronic metabolic disorder characterized by elevated blood sugar levels and encompasses various types like type 1, type 2, gestational, and prediabetes. This review delves into the intricacies of type-2 diabetes mellitus and its ideal management. Presently, a spectrum of herbal and synthetic drugs is employed for type-2 diabetes mellitus management. We gathered information about diabetes mellitus from articles published up to 2024 and listed in PubMed, Web of Science, Elsevier, Google Scholar, and similar databases. The keywords used in our search included "diabetes", "herbal drugs", "nano-carriers", "transdermal drug delivery", etc. By carefully analyzing the research on type-2 diabetes-mellitus, it was found that there is an increase in diabetes-based research, which can be demonstrated by contemplating the PubMed search engine results using transdermal delivery for type-2 diabetes-mellitus as a keyword. The oral consumption of these drugs is associated with numerous side effects, including obesity, pancreatic cancer, and hormonal imbalances. To surmount these challenges, the utilization of nano-carriers and transdermal drug delivery systems emerges as a promising avenue aiming to enhance the therapeutic efficacy of drugs. Nano-carriers represent a revolutionary approach, integrating cutting-edge technologies, inventive strategies, and methodologies to deliver active molecules in concentrations that are both safe and effective, thereby eliciting the desired pharmacological response. This review critically examines the constraints associated with traditional oral administration of anti-diabetic drugs and underscores the manifold initiatives undertaken to revolutionize drug delivery. This review focuses on the limitations associated with the conventional oral administration of anti-diabetic drugs and the many initiatives made so far for the effective and safe delivery of drugs using innovative constituents and techniques., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Orthodontic treatment typically requires an extended duration of 1-2 years to complete the treatment. Accelerating the rate of tooth movement during orthodontic treatment is essential for shortening the overall treatment duration. After the completion of orthodontic treatment, a prominent concern arises in the form of orthodontic relapse, where the teeth tend to revert to their original positions. This issue affects approximately 60% of the global population, underscoring the importance of implementing effective measures to address orthodontic relapse. An approach in this regard involves the targeted administration of herbal and synthetic drugs applied directly to the specific area of interest to facilitate tooth movement and prevent orthodontic relapse. Apart from this, researchers are investigating the feasibility of utilizing different types of nanoparticles to improve the process of orthodontic tooth movement. In recent years, there has been a noticeable increase in the number of studies examining the effects of various drugs on orthodontics. However, the currently available literature does not provide significant evidence relating to orthodontic tooth movement. In this review, the authors provide valuable information about the drugs and nanomaterials that are capable of further enhancing the rate of orthodontic tooth movement and reducing the risk of orthodontic relapse. However, a notable hurdle remains, i.e., there is no marketed formulation available that can enhance orthodontic tooth movement and reduce treatment time. Therefore, researchers should try herbal-synthetic approaches to achieve a synergistic effect that can enhance orthodontic tooth movement. In this nutshell, there is an urgent need to develop a non-invasive, patient-compliant, and cost-effective formulation that will provide quality treatment and ultimately reduce the treatment time. Another critical issue is orthodontic relapse, which can be addressed by employing drugs that slow down osteoclastogenesis, thereby preventing tooth movement after treatment. Nevertheless, extensive research is still required to overcome this challenge in the future., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)
