Abstract: A system for detecting an adulterant in a sample of milk. One or more drops of milk are added to a first location of a system and the presence or absence of the adulterant is detected in a second location of the system using a material treated with a detection reagent.

Abstract: Functional polyvalent oligomer for applications in medicine and biotechnology are disclosed. These oligomers have the formula (1) wherein R is H, CH3, C2H5, R1, is H, NH2, OH, COOH, X is N-Acetyl Glucosamine mannose, galactose and sialic acid, fructose, ribulose, erythrolose, xylulose, psicose, sorbose, tagatose, glucopyranose, fructose, deoxyribose , galactosamine, sucrose, lactose, isomaltose, maltos, cellobiose, cellulose and amylose, Y is H, COOH, OH or NH2, and n is from 3 to 50. The present invention also relates to synthesis of such oligomeric ligands. The method of synthesis of the present invention for oligomerization can be—applied to other ligands such as sialic acid, mannose and galactose and can—be used for the prevention of infections.

Abstract: The present invention relates to tri-block copolymers of molecular weight ranging between 2,000 Daltons to 2,00,000 Daltons having formula (1), having extraordinarily high binding strength, wherein, R1 is H, CH3, C2H5, or C6H5; R2 is H, CH3, C2H5, or C6H5; X is an ester or amide linkage; m is ranging from 3 to 500; n is ranging from 2 to 50; L is OH, NH2, OCH3, or NHCH(CH3)2; Y is N-Acetyl Glucosamine, mannose, galactose, sialic acid, fructose, ribulose, erythrolose, xylulose, psicose, sorbose, tagatose, glucopyranose, fructofuranose, deoxyribose, galactosamine, sucrose, lactose, isomaltose, maltose, cellobiose, cellulose, or amylose, a simple and effective process for the preparation of the tri-block copolymers of formula (1), and a method of preventing and/or treating microbial infections, wherein the said method comprises steps of exposing the microbe to the tri-block copolymer of formula 1, and thereafter, binding of the polymer to the microbe inhibits the microbial infection.

Abstract: The present invention relates to block copolymers for applications in medicine and biotechnology and synthesis thereof. Block copolymers comprise polyvalent N-Acetyl Glucosamine (NAG) which bind more efficiently to lysozyme than NAG itself. The effective inhibition is possible even at very low ligand concentrations than reported earlier. The block copolymers could be used for prevention and treatment of bacterial and viral infections. Moreover these polymers can be stimuli sensitive and be used for the recovery of biomolecules. The methodology of preparation of block copolymers reported here can be extended to other polymers and ligands such as sialic acid and used for preventing influenza and/or rotavirus infections. It also provides a method for preparation of block copolymers wherein polymers comprising sequences of specific ligands are essential.
