Thiacalix[4]arene-functionalized magnetic xanthan gum (TC4As-XG@Fe3O4) as a hydrogel adsorbent for removal of dye and pesticide from water medium

Arabic Gum-Grafted-Hydrolyzed Polyacrylonitrile@ZnFe2O4 as a Magnetic Adsorbent for Remediation of Levofloxacin Antibiotic from Aqueous Solutions

“…The Langmuir () and Freundlich () models are both expressed mathematically in the following equations C normale Q normale = 1 normalK normalL Q max + 1 Q max C normale ln .1em Q normale = ln .1em K normalF + 1 n .1em ln .1em C normale where C e is the equilibrium concentration of levofloxacin (mg/L); Q e and Q max are the equilibrium and maximum adsorption capacity (mg/g), respectively; K L (L/mg) and K F (L/mg) are the Langmuir and Freundlich constants calculated from the plot between C e / Q e and C e and between ln Q e and ln C e , respectively.…”

“…The Langmuir ( 4 ) and Freundlich ( 5 ) models are both expressed mathematically in the following equations. 54 where C e is the equilibrium concentration of levofloxacin (mg/L); Q e and Q max are the equilibrium and maximum adsorption capacity (mg/g), respectively; K L (L/mg) and K F (L/mg) are the Langmuir and Freundlich constants calculated from the plot between C e / Q e and C e and between ln Q e and ln C e , respectively. n is a factor to determine the favorability of the adsorption process; when n > 1, the uptake of levofloxacin onto adsorbent is desirable at high concentrations.…”

DNA hydrogels and nanogels for diagnostics, therapeutics, and theragnostics of various cancers

“…7,8 Nowadays, the compilation of Watson-Crick pairing methods and nucleotide synthesis strategies has opened new windows for researchers in the field of materials science. 9,10 Generally, hydrogels are considered as a highly appropriate substrate in various areas such as energy, [11][12][13] catalysis, [14][15][16][17][18][19] environmental sciences, [20][21][22][23][24][25][26] and medical applications. [27][28][29][30][31] Specifically, in the area of drug delivery to cancer tissues, hydrogels are widely used because they are capable of absorbing water molecules and swelling in the target organ, resulting in drug release in a controlled manner.…”

Benzene Sulfonyl Linked Tetrasubstituted Thiacalix[4]arene for Selective and Sensitive Fluorometric Sensing of Sulfosulfuron along with Theoretical Studies

“…Furthermore, they show superior conformational exibility than the regular Calix [4]arenes and higher complexation ability towards the metal ions or neutral molecules [30] [31]. Despite this, the literature on Thiacalix [4]arene based pesticides sensors is scarce and only few reports on sensing pesticides using Thiacalix [4]arene scaffold are available [32,33]. To the best of our knowledge, no uorescent sensor has been reported in the literature that selectively senses Sulfosulfuron using Fluorescence spectroscopy.…”
