Biopolymers are compounds prepared by using various living organisms, including plants. These are composed of repeated units of the same or similar structure (monomers) linked together. Rubber, starch, cellulose, proteins and DNA, RNA, chitin, and peptides are some of the examples of natural biopolymers. Biopolymers are a diverse and remarkably versatile class of materials that are either produced by biological systems or synthesize from biological sources. Biopolymers are used in pharmaceutical industry and also in food industry.Naturally derived polymers are also used for conditioning benefits in hair and skin care. Biopolymers have various applications in medicine, food, packaging, and petroleum industries. This review article is focused on various aspects of biopolymers with a special emphasis on role of biopolymers in green nanotechnology and agriculture.

Aloe vera (Aloe Vera L.) is a plant which commonly used by local people as moisturizer. The usage of aloe vera can be applied in form of peeled off gel mask with polyvinyl alcohol as gelling agent. The goal of this research is to determine the influence of increase of polyvinyl alcohol as gelling agent to the formulation of peeled off mask from aloe vera juice. The formulation was made in a few concentration, 10%, 12%, and 14% by adding 0,5% of aloe vera juice. After that, the formulation evaluated for 4 weeks about the organoleptics, homogenity, pH, drying time and viscosity. The date of pH test and drying time analyzed by using one way ANOVA statistically and then followed by Tukey HSD test and the viscosity analyzed by using Kruskall Wallis statistically which result in the significantcy less than 0,05 that mean there are difference in drying time and viscosity, on the other hand there is no difference in pH.

Abstract Nanofibers with bioactive agents are good candidates for skin-care applications due to high spesific surface area, low density and highly porous structure. In this study, hydrophilic based bioactive nanofibers were produced via an electrospinning and electrospraying simultaneous process. Polyvinyl alcohol (PVA), polyvinyl alcohol-gelatin (PVA-Gel) and polyvinyl alcohol-alginate (PVA-Alg) polymers were used as the matrix material and folic acid (FA) particles were dispersed simultaneously on the surface of these hydrophilic nanofibers. The morphology of the nanofibers (NFs) was uniform and dispersed folic acid particles incorporated into the structure of nanofibers as confirmed by scanning electron microscopy (SEM). Thermal behavior, chemical structure of the composite nanofibers were analyzed/investigated by thermogravimetric analysis (TGA) and Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy (ATR-FTIR) which showed that no chemical bonding between vitamin and polymers. A controlled release of FA-loaded electrospun fibers were carried out by UV-Vis in vitro study within the 8 hour-period in artificial sweat solutions (acidic media, pH 5,44). The obtained PVA/FA, PVA-Gel/FA and PVA-Alg/FA fibers released 49.6 %, 69.55 % and 50.88 % of the sprayed FA in 8 h, indicating the influence of polymer matrix and polymer-drug interactions, on its release from the polymer matrix. Moreover, biocompatibility of all developed novel NFs was assessed by two different cytotoxicity tests,3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and neutral red uptake (NRU) assay in L929 cell lines. In all cases, it is clearly concluded that these new electrospun fibers had fast-release of the vitamin and the hybrid process is suitable for transdermal patch applications, especially for skin-care products. Moreover, it has been proposed nanofiber with folic acid as a patch may prevent the COVID-19. The results of cytotoxicity assays on L929 cell reveal that all prepared NFs have no or slight cell toxicity. PVA and PVA-Gel with/without FA nanofibers seems more biocompatible than PVA-Alg nanofibers.

Test Result

Ultraviolet (UV) irradiation in biomaterial synthesis is commonly used to do sterilization and increase physical characteristics. This study had a goal to evaluate the characteristics of polyvinyl alcohol-Aloe vera (PVA-AV) nanofibers from the electrospinning process that was exposed by UV with the power of 8, 10, 15, and 20 W for 6 h. The physical properties of the fiber were characterized by using Scanning Electron Microscope (SEM), Fourier Transform Infrared (FTIR), Differential Scanning Calorimetry (DSC) test, and water absorption test. The SEM images showed that the nanofibers were formed with s homogeneous structure and no beads. The diameter and the thickness of the nanofibers increased with the increase of the power of UV exposure to the sample. The biggest diameter was 319.60 ± 56.17 nm at UV exposure power of 20 W. The FTIR test result indicated that there was no new chemical bond after the PVA-AV was exposed by UV. DSC test result showed that the increase of power could increase the melting temperature (Tm) with the highest value of 189.51°C at UV exposure power of 20 W. The water absorption test showed that the highest water absorption was 739.6 % at UV exposure power of 20 W.
