Therefore, in the present research work, a customized Mesoporous silica nanoparticle (MSiNPs) was designed by adapting the Stöber method with silane polymerization for Morin (MO) adsorption. The average size of MSiNPs was 50–130 nm as measured by TEM, while FE-SEM revealed a spherical surface shape. According to Raman and FTIR spectra, while the synthesis of MSiNPs, CTAB (a surfactant) was eliminated from MSiNPs, silane was functionalized, and with a loading efficiency of 10.28 ± 0.22%, MO was adsorbed. Molecular docking was used to perform <em>in-silico</em> studies to investigate the interaction of native MO with antidiabetic and antioxidant enzymes. Furthermore, the antioxidant and antidiabetic effects of both MO adsorbed MSiNPs, and native MO were examined <em>in vitro</em>, with the former showing promise even at lower concentrations than the latter. The cell survival experiment on Mouse macrophages RAW 264.7 and HCT cells revealed that MO adsorbed MSiNPs were nontoxic up to 15 μg/ml. The acute toxicity of different concentrations of MO adsorbed MSiNPs was also conducted in an <em>in vivo</em> model zebrafish (<em>Danio rerio</em>), where the study was conducted for about 96 h and evaluated for histological significance. The findings described above revealed that the MSiNPs were electrochemically, structurally, and thermally stable and MO adsorbed MSiNPs were nontoxic and biocompatible, implying that it might be an effective drug delivery vehicle for MO in the future. Moreover, in coming times, this nano-delivery system with effective biodistribution of the adsorbed MO could be explored as an antidiabetic and anti-cancer agent.</p></div>","PeriodicalId":37785,"journal":{"name":"OpenNano","volume":"10 ","pages":"Article 100126"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46146337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the understanding of the complex immune biology interactions within the Tumour Immune Microenvironment (TiME) is limited. This aspect, coupled with the unmet challenges pertaining to the development and testing of drug delivery modes and operations, has overall resulted in a large attrition rate with few anti-cancer therapeutics reaching the clinic. Also, a thorough understanding of the cellular features of the other components of the TiME in terms of the spatial and temporal heterogeneity of the cell types, stoichiometries, functional states will further aid in expediting the drug discovery process. Better understanding of the evolving immunological players within the Tumour Microenvironment (TME), that dictate the process of evasion governed by the tumours, will present opportunities for targeted interventions, including those involving NP-based delivery strategies. Moreover, development of more physiologically relevant models requires the utilization of ex vivo patient-specific materials or traditional cell line-based mono and/or heterotypic culture models that can recapitulate the TiME. Such models can be used to test potential drug candidates, including NP (nanoparticle)-based drug delivery constructs for their targetability, deep tumor penetration as well as the pharmacological responses efficiently and expeditiously. NP-based drug delivery requires the passage of the NP-drug conjugate through various anatomical and pathological barriers, before it reaches its site of action. One of the determinants affecting biodistribution, transport, uptake and clearance involves the dynamic protein corona (PC) around the NP that confers a new “biological identity”. Hence, the PC should be modelled using systems that will recapitulate their <em>in vivo</em> formation, evolution and turnover, aside from the employment of analytical tools for their characterization. In summary, this review focuses on elucidation of TiME composition, advancements in <em>in vitro</em>modeling of TiME constitution, various treatment strategies and nanocarrier approaches to counter adverse TiME for enhancement of drug efficacy in order to improve clinical response.</p></div>","PeriodicalId":37785,"journal":{"name":"OpenNano","volume":"10 ","pages":"Article 100134"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49077451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carcinogenesis relies on the tumour microenvironment because it contains tumour cells that communicate with neighbouring cells via the circulatory and lymphatic systems. During all stages of carcinogenesis, non-malignant cells in the tumour microenvironment promote unchecked cell proliferation. Changes in the genetics and epigenetics of tumour cells and the rearrangement of TME components, which happen when these two things work together, affect the formation and growth of tumours. Tissue-specific exchanges between tumour cells and their surroundings are critical to understanding the underlying mechanism. With the tremendous advancements in nanomedicine, TME modulation has made significant strides lately. Drug distribution using nanotechnology has a number of benefits, including increased circulation time, cargo delivery to the appropriate location, enhanced bioavailability, reduced toxicity, etc. High interstitial pressure and dense stroma prevent the extravasation and uniform distribution of nanocarriers in TME, but leaky vasculature, acidic, and hypoxic circumstances of TME aid in the aggregation of customised nanoparticles. The goal of the review is to look into the idea of the tumour microenvironment by doing a critical analysis of past research. By briefly analysing stromal components, therapeutic opportunities, and limitations provided by TME for nanoparticulate drug delivery, this paper primarily analyses the potential of nanotherapeutics in targeting TME. Additionally, updated details on TME remodelling techniques for better drug delivery and precise targeting of particular stromal components are provided.</p></div>","PeriodicalId":37785,"journal":{"name":"OpenNano","volume":"9 ","pages":"Article 100112"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49762152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most active crude EOs and their constituents like carvacrol, eugenol, geraniol, linalool, thymol, 1,8-cineole, etc. are not found in mainstream drug development modules due to their low solubility, poor bioavailability, and rapid volatility profiles, which reduce their potency, half-life, and pharmacokinetics to achieve the ideal drug-ability profiles.
