Nanomedicine are a relatively new but quickly expanding discipline in which tiny materials are used as diagnostic instruments or to administer therapeutic drugs to particular targets in a controlled manner. Nanotechnology provides a number of advantages in the treatment of chronic human diseases by allowing precise medications to be delivered to particular locations. There have been several notable uses of nanomedicine (chemotherapeutic agents, biological agents, immunotherapeutic agents, etc.) in the treatment of various illnesses in recent years. Neverthless, In current scenario there are phytochemicals are also present whom are responsible for prevention of devastating diseases. In this review it has been highlighted that there are real possible outcomes present, in the case of the combined treatment strategies of phytochemicals and nanoparticles. Eventually, this combined drug delivery system play crucial role in anti-cancer, anti-alzehimar, anti-bacterial and many more complicated maladies. We also focused on the preclinical and clinical study regarding the drug delivery system. Here, the types of phytochemicals along with their bioavilability also mentioned. Additionally, the Nanomedicines' advantages and disadvantages in drug delivery from synthetic to natural sources to clinical applications are also explored. In addition, we've added information about nanomedicine's developments by attaching with phytochemicals with respect to the diseases and future prospects.

Nanotechnology manifests the progression within stage of research and development, by increasing the efficacy of the merchandise through delivery of innovative solutions. to beat certain drawbacks associated with the traditional products, application of nanotechnology is escalating within the world of cosmeceuticals. In private care industry, cosmeceuticals are considered the fastest growing segment and thus the use has risen drastically over the years. Nanocosmeceuticals used for skin, hair, nail, and lip care, for conditions like wrinkles, photoaging, hyperpigmentation, dandruff, and hair damage, have inherit widespread use. Novel nanocarriers like nano emulsions, liposomes, microemulsions, niosomes, solid lipid nanoparticles, nanospheres and nanostructured lipid carrier have replaced the usage of conventional delivery system. These novel nanocarriers have advantages of controlled and sustained drug release, enhanced skin penetration, higher stability, high entrapment efficiency and site-specific targeting. However, nanotoxicological researches have indicated concern regarding the impact of increased use of nanoparticles in cosmeceuticals as there are possibilities of nanoparticles to penetrate through skin and cause health hazards. This review on nanotechnology utilized in cosmeceuticals highlights the various novel carriers used for the delivery of cosmeceuticals, marketed formulations, their positive and negative aspects, toxicity, and regulations of nanocosmeceuticals.

Objective: This study was aimed to analyze the inhibitory effect of the drugs used in nanocarrier as well as nanoparticles formulation based drug delivery system selected from PubChem database literature against 3CLpro (3C-like protease) receptor of SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) by implementing several in silico analysis techniques. Methods: This paper detailed a molecular docking-based virtual screening of 5240 compounds previously utilized in nanoparticle and nanocarrier drug delivery systems utilizing AutoDock Vina software on 3CL protease to discover potential inhibitors using a molecular docking technique. Results: According to the results of the screening, the top two compounds, PubChem Id 58823276 and PubChem Id 60838 exhibited a high affinity for the 3CL protease binding region. Their binding affinities were-9.6 and-8.5 kJ/mol, indicating that they were tightly bound to the target receptor, respectively. These results outperformed those obtained using the co-crystallized native ligand, which exhibited a binding affinity of-7.4 kJ/mol. PubChem Id 60838, the main hit compound in terms of both binding affinity and ADMET analysis, displayed substantial deformability after MD simulation. As a result of the VS and molecular docking techniques, novel 3CL protease inhibitors from the PubChem database were discovered using the Lipinski rule of five and functional molecular contacts with the target protein, as evidenced by the findings of this work. Conclusion: The findings suggest that the compounds discovered may represent attractive opportunities for the development of COVID-19 3CLpro inhibitors and that they need further evaluation and investigation.

Metronidazole is a synthetic nitroimidazole derived with antimicrobial and anti-inflammatory properties. The aqueous solubility of this drug is poor which results from low bioavailability. Limited effects on the removal of bacteria are shown in the local administration of plain metronidazole. The microemulsion system proves the efficacy of solubility and dissolution improvement of poorly watersoluble drugs such as metronidazole. The objective of this project work is to prepare and evaluate metronidazole containing topical water-in-oil microemulsion and to compare its effectiveness to other commercially available products. In this formulation, tween 80 is used as a surfactant and PEG 400 is used as a co-surfactant. In the oil phase, isopropyl myristate is used. Distilled water is used as the hydrophilic phase. The formulation of metronidazole containing microemulsion was evaluated for physicochemical parameters like pH, viscosity, conductivity, accelerated stability studies. In vitro release study was also performed to evaluate the release kinetics.

Nanoparticles (NPs) a potential next generation candidate for human well-being in the world of healthcare, have been observed to be effective anti-bacterial agents. The significance of nanoparticles as anti-bacterial agents has taken spotlight, due to the inability of pathogenic bacteria to develop resistance against NPs. In this review, mode of action of some scientifically important anti-bacterial NPs were discussed, along with summary of recent pre-clinical and clinical studies reported on anti-bacterial NPs are discussed. Some of the current hurdles and barriers that should be addressed to complete marketability and human applications, in regards to NPs as nanomedicines are also critically discussed along with focus on reported toxicity in NPs. Some additional pharmaceutical effects of NPs, reported in the recent years, such as antidiabetic and anticancer are also included for discussion. This review provides significant information on recent discoveries in the field of nanomedicines as antibiotics, that show promising future for drug development and drug delivery. As in every human domain, evidence begins to point to the actual undeniable fact that in conjunction with the existing medicine, nanomedicines could be the future of the healthcare that replace or enhance the potential current pharmaceutical drugs.
