This review work is a compilation of previously published methods for analysing Meropenem, either alone or in combination with other drugs. Many spectroscopic methods, such as derivative techniques and chromogenic techniques, were employed. A new and improved chromatographic method based on biological fluids and pharmaceutical formulations is also available. Aside from these two techniques, there are a few LC-MS/MS and HPTLC methods. In today's analytical research world, the quality by design or design by expert technique is used to obtain a better method for method validation. This concise review work can help an analyst choose the best method for developing and validating analytical methods.

Hair loss or Alopecia is a dermatological disorder with psychosocial implications on patients with hair loss. Leaves of Rosemarinus officinalis L (Lamiaceae) is traditionally known for hair growth activity. However efficacy of Rosemarinus officinalis is not reported for hair growth promoting activity. We have investigated the efficacy of extract of Rosemarinus officinalis L on hair growth promoting properties. Hydro-alcoholic extract of Rosemarinus officinalis L (5%) was evaluated for qualitative, quantitative chemical test and incorporated into hydro-gel base. The formulated gel was applied topically on shaved skin of Wistar albino rats and screened for hair growth activity. Rosemary gel significantly improved hair length and hair density. The present study reveals that Rosmarinus officinalis L is a good hair growth promoting herb and its extract is suitable for formulation as a gel for hair growth.

The nanotechnology sector is regarded as a developing technology due to its capacity to improve the already existing items and create new ones for a range of uses. The primary drivers of this expansion are cyclodextrin-based porous nanoparticles or distinctive nanosponges, which have lately been applied in the pharmaceutical, biomedical, and cosmetic industries. This superior technology can circumvent the defects of current techniques through its ability to attack and visualize tumor sites. The organization of this review article is such that we first looked at the distinctive characteristics of these nanosponges and the various synthesizing techniques, then about the drug loading and release principle and applications based on drug delivery, targeting, increasing the solubility of BCS Class II and IV drugs, other applications in biomedicine, and more. The most recent developments on the employment of biomimetic nanosponge as a pandemic tool because of the SARS-CoV-2 virus briefly align. Due to several significant limitations, effective targeted drug delivery systems have long been an aspiration. These issues might be resolved by the creation of new colloidal carriers termed Nanosponges.
