Un idrogel una rete tridimensionale (3D) di polimeri idrofili in grado di gonfiarsi in acqua e di trattenere una grande quantit d'acqua mantenendo la struttura grazie alla reticolazione chimica o fisica delle singole catene polimeriche. Il presente lavoro di ricerca riguarda l'effetto dei reticolanti sulla sintesi degli idrogel e il loro comportamento di rigonfiamento nelle soluzioni fisiologiche. Il comportamento reversibile di rigonfiamento-disgonfiamento degli idrogel in diverse soluzioni e le loro propriet ne raccomandano l'uso in applicazioni biomediche.

Ein Hydrogel ist ein dreidimensionales (3D) Netzwerk aus hydrophilen Polymeren, das in Wasser quellen und eine gro e Menge Wasser aufnehmen kann, wobei die Struktur durch chemische oder physikalische Vernetzung der einzelnen Polymerketten erhalten bleibt. Die vorliegende Forschungsarbeit befasst sich mit der Wirkung von Vernetzern auf die Synthese von Hydrogelen und deren Quellverhalten in physiologischen L sungen. Das reversible Quellungs- und Entquellungsverhalten der Hydrogele in verschiedenen L sungen und ihre Eigenschaften empfehlen sie f r den Einsatz in biomedizinischen Anwendungen.

This book comprises types of microorganisms, various tests (viz., typhoid, tuberculin, VDRL, pregnancy, and HIV tests), sterilization, and disinfectants. Different types of stains and staining procedures are explained. Blood and its clinical significance, Rh factor and blood grouping, blood collection, determination of RBCs, WBCs, platelets, and ESR, determination of glucose in the blood and urine samples, routine examination of urine samples, and estimation of total cholesterol, HDL, LDL, and triglycerides are discussed in a concise way. Colorimetry, microscopy, chromatography, immunochemical methods, gel electrophoresis, and the fundamentals of automation in clinical laboratories are all covered.

A hydrogel is a three-dimensional (3D) network of hydrophilic polymers which can swell in water and can hold a large amount of water also maintaining the structure due to chemical or physical cross-linking of individual polymer chains. The present research work covers the effect of crosslinkers on the synthesis of hydrogels and their swelling behaviour in the physiological solutions. The reversible swelling-deswelling behaviour of the hydrogels in different solutions and their properties recommends them for the use in biomedical applications.
