“…DDA of the present chitosan nanoparticles was calculated using FT-IR, and the results were 72.47, 84.18, and 96.11%, for Cs-NPs1, Cs-NPs2, and Cs-NPs3, respectively. The current results confirmed that the ball-milling process was the way to create chitosan in nano size, without altering the functional group properties, in agreement with the results carried out by Taher et al (2019) and Sari et al (2019). The present chitosan nanoparticles: Cs-NPs that had been physically manufactured were assessed the extent of its effect for the first time all over the world on the viability of protoscoleces of Echinococcus granulosus.…”

Hydatid cysts of Echinococcus granulosus were recovered from 27.59% (149/540) of camels Camelus dromedarius from a slaughterhouse in Cairo. The organ distribution of cysts was 57=38.26% in the lung, 65=43.62 % in the liver, 23=15.44 % in both liver and lungs, and 4=2.68% in the other organs such as the brain, tongue, and spleen, etc. The investigation looked at how four compounds from scorpions: chitosan, chitosan nanoparticles (Cs-NPs), venom as well as venom-loaded chitosan nanoparticles (V-CN) affect against in vitro hydatid cyst protoscoleces. Aseptically, cyst fluid protoscoleces were aspirated. Each of the aforementioned compounds was always examined in triplicates at doses of 20, 50, and 100 µg/ml for incubation periods of 30, 60, 120, and 240 min to show its scolicidal effects. Using the 0.1% eosin test, the viability of protoscoleces was determined.According to the degree of deacetylation (DDA), concentration, exposure period, and size, all compounds demonstrated statistically significant differences (P > 0.05) against the protoscoleces activity. Chitosan and chitosan nanoparticles had a scolicidal action, directly related to DDA and inversely proportional to size. The most effective scolicidal compound was venom-loaded chitosan nanoparticles, which destroyed all protoscoleces at a concentration of 100 µg/ml, after 240 min of incubation.

“…However, the peak at 10° disappears on heat treatment. Further, chitosan of low molecular weight had a peak at 20.5° (JCPDS 039-1894), and that of high molecular weight exhibited a peak at 22.5° . This indicates that the chitosan we used is of high molecular weight.…”

Liu et al 47 have found peaks corresponding to 2θ values of 5.25°, 14.9°, 16.75°, 19.2°, and 21.35°for pure chitosan.…”

“…Srinivasa et al 36 have also reported that chitosan films fabricated via oven drying led to a crystallinity index of 43.3%. Sari et al 53 found the crystallinity index of pure chitosan films as 49%. The crystallinity index as well as the 2θ peaks of our films being the same as those in the literature establishes the confidence in the fabrication procedures and the quality of films.…”

Toward establishing the full design aspects of chitosan as a packaging material or as cling wraps, the chemical characteristics, thermal stability, optical transparency, Young’s modulus, elongation at fracture, and burst strength of pure and glycerol-added 100 μm-thick-chitosan films were investigated. Films of chitosan and films with 10%, 20%, and 30% w/w glycerol as the plasticizer were prepared per standard protocols. Electron microscopic analysis revealed that all films are homogeneous. The addition of glycerol did not alter the crystallinity, lowered the glass transition by ∼7 °C, decreased the thermal stability, decreased the roughness by 50%, and increased the optical transparency by 5%. It was found that the incorporation of glycerol decreased the Young’s modulus by two orders, increased the plastic strain at least by four times, and decreased the burst strength by at least two times. The results from this systematic analysis, including comparisons with existing packaging materials, provide a holistic picture for tailoring the properties of chitosan-based packaging materials for modified atmosphere packaging (MAP) toward sustainable development.

“…However, a slight difference in the DA degree was observed. This might be caused by very little crystallization damage in chitosan (Taher et al, 2019), (Sari et al, 2019). Additionally, Laka and Chernyavskaya (2006) concluded that following ball-milling, the DDA of the produced chitosan nanoparticles did not vary appreciably.…”

Aim: This investigation aims to extract chitin and chitosan from the three scorpions: Leiurus quinquestriatus (LQ), Androctonus crassicauda (AC) and Androctonus amoreuxi (AA) for the first time and to determine the loading capacity and efficiency of LQ venom-loaded chitosan nanoparticles (V-CN). Methods: chitin was extracted and converted to chitosan which is converted to nanoparticles (Cs-NPs) by ball-milling technique. LQ venom was collected, characterized, and loaded on Cs-NPs via the ionic gelation method. Different techniques were used to characterize the obtained compounds. Results: the dried powder of LQ, AC, and AA contained 19.7 %, 15.4 %, and 15 % chitin, respectively. FT-IR confirmed the successful preparation of chitin, chitosan, and V-CN samples. Loading capacity reached 76.50 %, while encapsulation efficiency reached 87.98 %. Conclusion: scorpion venom was effectively loaded on chitosan samples. Its physical and compound qualities, specifically, were viewed as great for biomedical and drug applications.
