Phytosomes(phytophospholipid complex) are dosage forms that have recently been introduced to increase the stability and therapeutic effect of herbal medicine. Currently, bioactive herbs and the phytochemicals they contain are considered to be the best remedies for chronic diseases. One promising approach to increase the efficacy of plant-based therapies is to improve the stability and bioavailability of their bio-active ingredients. Phytosomes employ phospholipids as their active ingredients, and use their amphiphilic properties to solubilize and protect herbal extracts. The unique properties of phospholipids in drug delivery and their use in herbal medicines to improve bioavailability results in significantly enhanced health benefits. The introduction of phytosome nanotechnology can alter and revolutionize the current state of drug delivery. The goal of this review is to explain the application of phytosomes, their future prospects in drug delivery, and their advantages over conventional formulations.

This study demonstrates a facile and economical approach for fabricating laser-induced graphene（LIG）, which results in improved electrochemical performance. Polyimide polymer was used as a starting material for LIG synthesis and irradiated under ambient conditions using a CO2laser. The prepared LIG samples were characterized by Raman spectroscopy and FTIR, which validated the formation of multilayered graphene containing sp2 hybridized C=C bonds. The FE-SEM revealed three-dimensional sheetlike structures, while HR-TEM images displayed lattice planes with an interplanar spacing of approximately 0.33 nm, corresponding to the（002） plane of graphene. The electrochemical performance of the as-prepared LIG samples demonstrated a remarkable areal specific capacitance（CA） of 51 mF cm-2(170 F g-1) at 1 mA cm-2(3.3 A g-1) in a three-electrode configuration with 1M KOH as the aqueous electrolyte. The LIG electrodes produced an energy density of ～3.5 μWh cm-2and a power density of ～350 μW cm-2,demonstrating significant energy storage capabilities. Additionally, the electrodes exhibited excellent cyclic stability, retaining 87%of their specific capacitance after 3 000 cycles at 1 mA/cm2. The symmetric supercapacitor fabricated with LIG electrodes and the tested 1M KOH electrolyte showed a specific capacitance of 23 mF cm-2and maintained excellent retention after 10,000 cycles,showing LIG's potential for supercapacitor applications.
