Summary: The main purpose of this paper is to design curcumin loaded PLGA nanocapsules for the selective detection of dopamine using fluorescence spectroscopy. The nanocapsules were synthesized using a solid-in-oil-in-water (s/o/w) emulsion technique and were coated with a poly(diallyldimethylammonium)chloride (PDDA) polymer. The nanocapsules showed high selectivity and specificity towards dopamine, and the fluorescence emission technique was found to be selective, easy, fast, and low cost for the determination of dopamine.

Summary: Mesoporous silica nanoparticles (MSN) are potential drug carriers with high drug loading capacity and degradability under biologically relevant conditions. Dissolution studies of MCM-48 MSN in the presence of proteins show that protein concentration affects the kinetics of dissolution and leads to the formation of core-shell structured particles. The results suggest that MSN dissolution kinetics is faster under typical in vitro conditions compared to full serum conditions.

Summary: In this study, melatonin was encapsulated in mesoporous silica with the addition of a coating of cellulose acetate phthalate. The release kinetics of melatonin and its metabolism were investigated in simulated gastrointestinal fluids and in an in vitro model of the intestinal tract. The presence of the coating affected the release and absorption of melatonin, as well as its catabolism. The confinement of melatonin in the mesopores had a slight impact on its permeability and metabolism.

Summary: The pristine and Ni-doped BaNixFe12-xO19 nanoparticles were fabricated via a microemulsion approach, and the impact of dopants on the dielectric, optical, structural, and photocatalytic properties was investigated. The doped nanoparticles exhibited enhanced remanence, saturation polarization, and photocatalytic degradation activity. The optical band gap was reduced due to the doping, and the dielectric properties were also improved. The highly doped catalyst demonstrated efficient electron-hole pair separation and achieved a higher degradation rate of crystal violet dye under visible light irradiation.

Summary: This study focused on the removal of Drimaren Turquoise CL-B reactive dye using the white rot fungus Schizophyllum commune, considering current environmental conditions. Various parameters such as pH, carbon and nitrogen sources, temperature, dye concentration, and C/N ratio were investigated. The highest dye removal (95.45%) was achieved at pH 4.5, temperature 35°C, inoculum size 3 mL, veratryl alcohol mediator, glucose carbon source, and ammonium nitrate nitrogen source. The enzyme activity assay showed low laccase and lignin peroxidase (LiP) activity, while manganese peroxidase (MnP) activity was the highest. Maximum biosorption occurred at pH 1 and 313 K. The pseudo-2(nd)-order kinetic model and Freundlich isotherm were the best fit for dye removal. Overall, white rot fungus shows promise as an excellent biomaterial for removing synthetic dyes from wastewater.

Summary: The purpose of this study was to develop a stable lyophilised finasteride nanosystem (FNS-NS) for topical delivery. The FNS-NS was fabricated using ultrasonication and the impact of different cryoprotectants on its characteristics was investigated. The lyophilised FNS-NS showed spherical shape, a particle size range of 188.6 nm +/- 4.4 to 298.7 nm +/- 4.7, low PDI values, and zeta potential within -38.3 to +53.3 mV. Confocal laser microscopy demonstrated higher cellular internalisation for undecorated FNS-NS compared to its chitosan-decorated counterpart. The lyophilised FNS-NS remained stable for 90 days and the FNS-NS with 15% trehalose showed promising attributes for topical delivery in treating androgenic alopecia.

Summary: This study evaluated the feasibility of co-loading plain ranitidine hydrochloride (RHCl) and microencapsulated flurbiprofen (FBP) in a Lycoat (R) RS780-based oral fast disintegrating film (ODF). The composite ODF with RHCl and FBP showed a controlled release of FBP and rapid release of RHCl. The optimized formulation (F2) exhibited higher anti-inflammatory activity and gastroprotective effects compared to pure FBP and other formulations. F2 also showed sustained anti-inflammatory effect and reduced levels of cytokines. The Lycoat (R) RS780-based composite film could be a promising carrier for the co-loading of microencapsulated FBP with RHCl.
