The invention generally relates to methods for quantifying an amount of enzyme molecules. Systems and methods of the invention are provided for measuring an amount of target by forming a plurality of fluid partitions, a subset of which include the target, performing an enzyme-catalyzed reaction in the subset, and detecting the number of partitions in the subset. The amount of target can be determined based on the detected number.

The invention generally relates to performing sandwich assays in droplets. In certain embodiments, the invention provides methods for detecting a target analyte that involve forming a compartmentalized portion of fluid including a portion of a sample suspected of containing a target analyte and a sample identifier, a first binding agent having a target identifier, and a second binding agent specific to the target analyte under conditions that produce a complex of the first and second binding agents with the target analyte, separating the complexes, and detecting the complexes, thereby detecting the target analyte.

The basis to develop a cosmetic and pharmaceutical composition based on a combinatorial derivative of quercetin in the form of nanoparticles (liposomes) for the treatment of atherosclerosis and its complications, as well as hypertension, for rejuvenating the body and healing wounds.

The problem is solved by obtaining a cosmetic and pharmaceutical composition based on a combinatorial quercetin derivative, characterized in that the modified combinatorial quercetin derivative is represented as a combinatorial library (mixture) of quercetin derivatives obtained by simultaneous combinatorial modification of quercetin with at least two alkylating and acylating modifiers in the combinatorial reaction synthesis to obtain the maximum number of different derivatives of quercetin, and as biologically active substances, a whole combinatorial mixture of quercetin derivatives is used without separation into individual components to create cosmetic and pharmaceutical compositions.

The present invention features a number of methods for identifying one or more compounds that bind to a biological target. The methods include synthesizing a library of compounds, wherein the compounds contain a functional moiety having one or more diversity positions. The functional moiety of the compounds is operatively linked to an initiator oligonucleotide that identifies the structure of the functional moiety.

Disclosed herein is a method of generating a combinatorial library of products having a diverse array of properties. In particular, the method comprises: (a) selecting one or more pairs of reactants comprising complementary functional groups; (b) mapping all possible bond arrangements between the complementary functional groups of each pair to provide a library of possible products; (c) analyzing one or more properties of each possible product to select one or more products with desired properties (desired products); and (d) synthesizing the one or more desired products. Further disclosed herein is a method that involves the retrosynthetic reduction of a complex molecule into simple starting materials.
