However; the physicochemical factors of drug and biological processes significantly affects the absorption of drug. The co-administration of oral formulations along with the meal is a major factor that governs the bioavailability of drugs in comparison to the fasting state by varying the transit time. Presence of food alters the gastric emptying rate, gastric pH, bile flow, hepatic and splanchnic blood flow along with it leads to the physical interaction with drug which creates trouble in rate and extent of absorption. One needs to consider the possible food-drug interaction while deciding the dose and type of formulation. The presence of food can dramatically change the effect of a drug, with both possibilities being either a less therapeutic effect than expected due to a lower absorption of the drug or unexpected side effects as a consequence of the rapid absorption of the drug. Commonly used drugs like propranolol and ketoconazole showed improved absorption in presence of food, whereas; levothyroxine and ciprofloxacin found to be 40–50 % less bioavailable after meal. Henceforth; by considering the food impact on the drug’s bioavailability, many of regulatory agencies are now demanding the data in association with the food-induced dissolution and absorption of drugs. In recent years, researchers have taken the initiative and developed different kinds of dosage forms to tackle the problem of drug-food interactions.

However, oral administration of these macromolecules is challenging due to gastrointestinal (GI) tract degradation due to the harsh pH conditions, digestive enzymes, mucus layers and gastric acid. These barriers cause degradation affect the absorption and reduce the bioavailability of drugs. Thus, the bioavailability achieved by oral administration is less compared to parenteral administration. But parenteral administration of drugs causes reduced patient compliance, invasive and most painful. On the other hand, oral administration is non-invasive painless, but also results in higher patient compliance. Smart ingestible devices like microneedle devices, microrobots, magnetically triggered capsules, self-unfolding foils, smart pills, SOMA, LUMI, nano-straws and gastric auto-injectors can help resolve the issues related to oral delivery of bioactive agents and therapeutics. These devices overcome the GI tract barriers and successfully carry out the oral delivery of these drugs in the GI tract. This review explores how these smart ingestible devices can be an innovative alternative to the parenteral administration of bioactive macromolecules and biotherapeutics. It also covers the devices' functioning, mechanism, clinical stages and challenges in clinical transition. Our review article stands out in the current body of literature by comprehensively compiling all categories of ingestible devices for oral delivery, including the mechanism of drug release, monitoring, therapeutic systems and applications.

Standard treatments, including surgery, radiotherapy, and chemotherapy with temozolomide (TMZ), are often limited by the ability of the tumor to circumvent therapeutic effects and by the physiological barriers that restrict drug delivery to the brain parenchyma. Specifically, the blood-brain barrier (BBB) and the blood-brain tumor barrier (BBTB) impede the effective concentration of therapeutic agents within the brain, posing a significant challenge in treating GBM. The primary focus of current research has pivoted towards nanotechnology to address these limitations. Due to their size, surface modifications, and capability to encapsulate drugs, nanocarriers like polymeric, metallic, and lipid nanoparticles have shown potential in enhancing the penetration of anticancer agents across the BBB and BBTB, thus increasing treatment efficacy and minimizing general toxicity.

Owing to the success of former studies of different group III-V binary nanotubes, this study has been performed by using density functional theory (DFT) with the B3LYP functional and LanL2DZ basis set in Gaussian 09 to explore the impact of transition metals (TMs) Vanadium (V), Niobium (Nb), and Tantalum (Ta) on structural, electrical, thermodynamic, and optical properties of two different variants- armchair and chiral structured GaNNTs (Ga<sub>30</sub>N<sub>30</sub>) to understand their comparative behavioral changes. The study reveals that doping GaNNTs with V, Nb, and Ta significantly enhances structural stability, especially when replacing the Ga atom. This improved structural stability suggests the potential for tailoring their electronic and mechanical properties. Again, in the case of Nb doping, replacing the N atom increases surface area and enhances reactivity, indicating its potential application in sensor development. Moreover, IR spectroscopy predicts the possibility of the natural existence of energetic favorability of all dopant-modified nanotubes with distinct vibrational signatures.

Furthermore, the armchair (3, 3) Ga<sub>30</sub>N<sub>30</sub> systems exhibit higher structural ordering after doping than the chiral (5, 3) Ga<sub>30</sub>N<sub>30</sub> systems.

It has surface area 110–1000 m<sup>3</sup>/g, pore volume 0.4 – 1.5 cm<sup>3</sup>/g and pore diameter 2 – 15 nm. Other physicochemical properties of amorphous biosilica are whiteness index (93.24–96.66), water content (0.49–2.81 %), density (0.56–0.95 g /ml) and antifungal properties. A mesoporous biosilica nanoparticles from rice husk have a spherical shape, highly ordered hexagonal structure, large specific surface area (&gt;973 m<sup>2</sup>/g), high pore volume (&gt;0.87 cm<sup>3</sup>/g), and pore diameter (&gt;2.7 nm), which make it a potential material for colloidosome fabrication. Therefore, preparation, structural characterization, loading factors, and merits of biosilica nanoparticles in colloidosome fabrication for drug delivery are discussed, as well as their health risk assessment, benefits, and prospects. The study also highlights that the resulting colloidosome microcapsules and their resistance to harsh conditions are influenced by factors like particle’s porosity, shape, surface chemistry, and surface-area-to-volume ratio, which are characteristic of biosilica nanoparticles derived from rice husks.</div></div>","PeriodicalId":100959,"journal":{"name":"Next Nanotechnology","volume":"7 ","pages":"Article 100192"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144242821","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}
