Nanotechnology has emerged as a game-changing tool for enhancing biofuel yield, purity, and efficiency, offering significant commercial potential. This review critically examines the applications of various nanomaterials—such as graphene, carbon nanotubes, metallic nanoparticles, nanocomposites, and nanoscale biochar—in enhancing the conversion of diverse feedstocks, including lignocellulosic biomass, microalgae, and organic waste, into biodiesel, bioethanol, biohydrogen, and biogas. The novel integration of metallic nanoparticles and carbon-based nanomaterials in enzymatic hydrolysis, transesterification, and fermentation has markedly improved biofuel yields and reduced production costs, creating opportunities for scalable and commercially viable biofuel production. Additionally, nanomaterials enhance biofuel quality by facilitating advanced purification techniques that optimize separation processes. Despite these promising advancements, environmental and toxicity concerns surrounding the use of nanoparticles remain significant challenges. This study identifies key research gaps, including scalability, lifecycle assessments, and establishing regulatory frameworks, which must be addressed for effective commercialization. Future research must optimize the synthesis of eco-friendly, cost-effective nanoparticles while minimizing environmental risks.

The traditional solidifying adsorption approach failed to overcome the instability issue and produced a powder with a high dosage. Combining in-situ liquefying (poloxamer 188) and pH-modifying agents (sodium bicarbonate) was invented to address these challenges while maintaining dissolution performance. Therefore, five formulations were prepared, namely: liquid SNEDDS (L-SNEDDS), solid SNEDDS (S-SNEDDS), carbonated SNEDDS (C-SNEDDS), in-situ liquefying SNEDDS (IL-SNEDDS), and in-situ liquefying carbonated SNEDDS (IL-C-SNEDDS). Oil and cosurfactant ingredients were selected based on the solubility of the drug and poloxamer 188, respectively, while surfactant was selected based on transmittance measurement. Moreover, the prepared formulations were characterized using a Zetasizer, pH meter, thermal behavior, SEM, FTIR, PXRD, and dissolution apparatus. Finally, the stability of prepared formulations was studied to assess the impact of formulation type on drug stability. Results showed that atorvastatin calcium exhibited the highest solubility in imwitor 308 (181.4 mg/g) among tested oils. The optimized SNEDDS formulation displayed a transmittance value of 98.62%, indicating excellent emulsification with a particle size of 10.5 nm. The optimized L-SNEDDS formulation comprises tween 80, propylene glycol, and imwitor 308 (2: 1: 1). The results showed that Syloid successfully adsorbed L-SNEDDS, which was present in an amorphous state. In vitro dissolution studies demonstrated that all SNEDDS formulations achieved > 90% drug dissolution. However, notable drug degradation was observed with liquid and solid SNEDDS (> 10%) compared to < 5% in IL-C-SNEDDS.
