Article Abstract
Tinctures are alcoholic or hydroalcoholic solutions prepared from vegetable or chemical substances. The concentration of the solute varies up to a maximum of 50%, e.g., vanilla tincture. Tinctures are very useful in the perfume industry because they contain ethanol, which can dissolve molecules such as fragrant molecules, and consequently form hydroalcoholic formulations together. Recently, we have shown that nanostructures exist in the monophasic water-ethanol-citronellol system, and it is therefore a question whether such nanostructures exist in a system where a perfume molecule of citral is present as the oil component instead of citronellol. In this study, the single-phase region was mapped conductometrically and then measured by Dynamic Light Scattering (DLS) and UV/Vis spectroscopy to determine the presence of nanostructures similar to classical microemulsions.

Glioblastoma multiforme (GBM) is the most prevalent malignant brain tumor, with an average survival time of 14 to 20 months. Its capacity to invade brain parenchyma leads to the failure of conventional treatments and subsequent tumor recurrence. Recent studies have explored new therapeutic strategies using a chemoattracting gradient to attract GBM cells into a soft hydrogel trap where they can be exposed to higher doses of radiation or chemotherapy.
Bacterial infections pose an increasingly worrisome threat to the health of humankind, with antibiotic resistance contributing significantly to this burden. With current conventional antibiotics perpetuating the problem, and a paucity in developing antibiotics, drug delivery systems incorporating nanotechnology appear promising. As such, a dual enzyme-responsive multifunctional nanostructured lipid carrier (NLC) incorporating farnesol (FAN) and triglycerol monostearate (TGMS), was conceptualized for the codelivery of vancomycin (VCM) and antimicrobial peptide (AMP) to enhance the antibacterial activity of VCM.
Nanoparticle-based therapies represent a transformative approach to managing gynecological cancers, offering targeted treatment strategies that minimize harm to healthy tissues while maximizing therapeutic efficacy. Despite their potential, implementing these advanced treatments in Africa is needed by a complex interplay of technological, economic, regulatory, and ethical challenges. This paper examines the current landscape of nanoparticle-based therapies, identifying critical barriers to their adoption, including inadequate infrastructure, high costs, and insufficient regulatory frameworks.
Carbon-nanotube-modified biochar (CNT3-CBC) with a nanostructured surface was prepared by using cattle manure as the raw material via the impregnation method. This modified biochar was then used to adsorb petroleum and Ni(II) from aqueous solutions. Various physicochemical characterization techniques were employed, including SEM, BET analysis, FTIR, and XPS.
Background: Ciprofloxacin is a widely used antibiotic in medicine and agriculture. It can cause pollution to the environment and food, thereby affecting human health.
Objective: This study proposes the preparation of molecular imprinted fluorescent sensors and their selective detection of ciprofloxacin, with the aim of achieving specific recognition and accurate detection of ciprofloxacin.
