Abstract

Cocrystal of p-Methoxycinnamate acid-succinic acid has been produced by microwave irradiation and solvent evaporation methods. Cocrystals are formed using succinic acid as the coformer at a molar ratio of 1:1. The formation of cocrystal can be done by solvent evaporation method and microwave radiation method. Physicochemical properties have been studied by FT-IR, DSC, PXRD, and SEM analysis. The solubility test was carried out with pH 6.8 phosphate buffer at a temperature of 25±0.5°C for 5 hours and the dissolution test was carried out with 900 mL pH 6.8 phosphate buffer at a temperature of 37±0.5°C with the speed of 75 rpm using a paddle-type dissolution test apparatus. The solubility of PMCA has increased its solubility in cocrystals by the solvent evaporation method by 1.19 times and by the microwave radiation method by 1.16 times compared to PMCA. The dissolution rate of the cocrystals of the solvent evaporation method increased by 3.50 times and the cocrystals of the microwave radiation method increased by 2.29 times compared to PMCA.

Abstract

The development of nanotechnology in the world is very rapid, and the applications of nanotechnology can be felt in various fields in everyday life. For instance, to control food, nanotechnology plays a role in creating early detection tools for food additives, which are known to be dangerous if consumed by humans in excess, such as the presence of colorants that are not permitted or food additives that exceed tolerance limits. Nanosensors based on screen print electrodes (SPE) are devices that can be used for detection with various notable properties such as fast, sensitive and portable. Seeing the importance of developing and down streaming nanotechnology to society, education regarding the role of nanotechnology needs to be carried out. In this activity, nanotechnology applied in the manufacture of nanosensor devices was introduced, especially to analysts at the drug and food control center and the health service. Apart from that, through this activity, sustainable collaboration can be established between the community service team who are researchers in the field of nanosensors and users in the field who are drug and food regulatory bodies, to develop nanosensor technology according to needs in the field. This activity will be carried out in Pontianak, West Kalimantan, specifically aimed at pharmacists and analysts in the drug and food control center, health service, and industry and trade service (Disperindag). This activity will include education about nanotechnology applications in various fields as well as a demonstration on the use of SPE-based naosensor devices. From this event, in future the analyst may do the analysis in field without waiting long time analysis in laboratory. From this community service activities, scientific articles and publications can be produced in print/electronic media, as well as videos of community service activities, in accordance with the main performance indicators determined nationally.

Abstract

Selenium nanoparticles (SeNPs) have gained attention in the medical field because of their enhanced bioactive properties and bioavailability. The green synthesis of nanoparticles offers an eco-friendly synthesis method. In this study, Abelmoschus esculentus (okra) extract was used for the green synthesis of SeNPs. The synthesized SeNPs were characterized using UV-visible (UV-vis), scanning electron microscopy-energy dispersive X-ray (SEM-EDX), Fourier-transform infrared spectroscopy (FTIR), and particle size analyzer (PSA). UV-vis analysis showed a peak at a wavelength of 288 nm, and the SeNPs demonstrated stability at low temperatures for up to 30 days. FTIR analysis indicated interactions between the pectin functional groups on okra and the surface of SeNPs. The SeNPs had a 6.48 nm diameter and polydispersity index of 0.13. A spherical morphology was observed in the nanoparticles. The antioxidant activity of SeNPs was evaluated using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) methods. The results showed a dose-dependent increase in free radical inhibition with 31.44 and 15.37% by DPPH and ABTS tests, respectively. The green synthesis of SeNPs using okra extract produced nanoparticles with unique properties based on several characterization results. In conclusion, SeNPs exhibited promising antioxidant activity, highlighting their potential for biomedical applications.
