conservative remedies have a gray history worldwide and these provide productive and pertinent tools to tackle ailments. Also, the high altitude areas of indian Himalayas with their wealthy biodiversity anchorage around 2000 plant species. Ensuing study demonstrates the synthesis of Silver (Ag) and gold (Au) nanoparticles (nps) and utilizes one of the medicaments Curcuma longa of Indian Himalayas collected from different altitudes. For the same, turmeric rhizome extracts have been prepared from the aforesaid medicament and its anticancer activity and antimicrobial potential have been evaluated. formation of Ag and Au nanoparticles was realized via UV-Vis spectroscopy and transmission electron microscope (TEM) confirmed size of the NPs. Antibacterial activity has been checked against Bacillus subtilis and Escherichia coli. the anticancer prospective has been observed against A549 and PC3 cell lines of both Au and Ag NPs and the cytotoxicity on PC3 and A549 cell lines was assessed using Mtt assay. Results revealed higher amount of biochemicals, antibacterial and anticancer activity in Ag and Au nps synthesized from rhizome extract collected from highest altitude. For the first time impact of altitudinal variations on phytochemicals and nanoparticles has been reported which have significant effect on its antimicrobial and anticancerous activity.

“…The creation or development of hydrophobic surfaces with (or without) antibacterial function on cellulose materials uses a number of technologies, such as, chemical coating methods using a mixture of 1H,1H,2H,2H-perfluorooctyltriethoxysilane, 3-(trimethoxysilyl)-propyldimethyloctadecyl ammonium chloride, and P,P-diphenyl-N-(3-(trimethoxysilyl) propyl) phosphinic amide [5] or fluoroalkyl-functional siloxane [6] through a sol-gel process; laccase-catalyzed hydrophobization with lauryl gallate [7] and grafting with eugenol [8] or ferulic acid [9]; thermochemical fabrication and impregnation of silver nanoparticles with starch [10]; sonochemical cohydrolysis and cocondensation with tetraethyl orthosilicate and alkyltrialkoxysilanes [11]; and physical pad-dry-cure method with MgO/methyl silicate nanocomposites [12].…”

It is of significant interest to create functional flexible surfaces that simultaneously exhibit high water-resistance and antimicrobial performances for medical or packaging applications. This study reported a synthesis of functional surface coating on flexible cellulose materials (filter papers) with ZnO nanoparticles and binds of renewable soybean oil-based polymers. Self-aggregation of ZnO nanoparticles could form ZnO particles with two regular morphological patterns. Rather than a rod-like morphology, a flower-like ZnO benefited a promotion of surface hydrophobicity. Moreover, surface with the flower-like ZnO showed a 51.6% promotion on antimicrobial activities against Gram-negative bacteria (E. coli) than the rod-like ZnO. A low binder/ZnO ratio of 0.2 led to a remarkable improvement on water repelling performances without negative effects on a coating adhesion of ZnO. Under this condition, a hydrophobic surface was achieved with a large static contact angle of 138° when applying ZnO nanoparticles at a dosage of 3 g m−2.

“…23 However, some of its inherent shortcomings are a low melt strength and viscosity, as well as low gas barrier properties. Our research group studied PBS as the polymeric matrix in composite materials containing LDH, 8,9,12,[16][17][18][20][21][22] graphene, 24 lignocellulosic fibers [25][26][27][28] and rice endosperm 29 with the aim of improving its technical performances. PBSA is a copolymer of PBS containing a potentially biobased comonomer: dimethyladipate.…”
