Abstract: In various aspects and embodiments, the present invention is directed to versatile, label-free method for the quantitative and qualitative detection of biomarkers and/or other compounds in a fluid sample using functionalized microparticle aggregates. In these methods, micron-scale particles are functionalized to specifically interact with the biomarker being measured and added to the sample to form aggregates, the size and number of which are counted to find a volume fraction and/or number fraction of aggregates in the sample. There is a direct correlation between the volume fraction and number fraction of these aggregates and the concentration of the corresponding biomarker. By comparing the measured volume fraction and/or number fraction of aggregates in the sample to a calibration curve, the concentration of that biomarker may be determined even for biomarkers or other target compounds in samples at very low concentrations, without the need for fluorescence and enzyme labelling of antibodies.

Abstract: A method of synchronizing the display of instant messages between multiple clients is performed at a computer system. Upon receipt of a first synchronization request from a client, the first synchronization request including a conversation identifier and a last message timestamp, the computer system identifies a conversation including a set of messages associated with the conversation identifier. The set of messages was generated after the last message timestamp and have not been received by the client. The computer system then assigns display parameters to the set of messages based on their read-or-not indicators, content, and their temporal relationship with other messages in the conversation. Next, the computer system sends the set of messages and their respective display parameters to the client in a reverse chronological order. The client then displays the set of messages in accordance with their respective display parameters.

Abstract: The present invention is directed to facile method of zwitteration of polysaccharides or other polymers with carboxybetaine (CB) or another zwitterionic betaine. Zwitterionic CB functional groups were seamlessly integrated onto dextran backbone via a one pot reaction. Different degrees of substitution were achieved by repeating the reaction and controlling the ratio of reactants. CB side groups in CB-functionalized dextran (CB-Dex) can switch between cationic and zwitterionic forms under acidic and neutral conditions. The ring structure formation was confirmed by heteronuclear multiple-bond correlation (gHMBC) 2D-NMRAntifouling properties of CB-Dex were tested in the form of hydrogel using a fluorescent method. The amount of adsorbed protein decreases dramatically with the increase of CB content. For the cell attachment study, there was almost no cell attaching on the CB-Dex hydrogel surface with the higher CB content.

Abstract: The present invention is directed to a versatile and high performance zwitterionic CP platform, which integrates all desired functions into one material. This zwitterionic CP consists of the conducting backbone and multifunctional zwitterionic side chains. Non-conducting zwitterionic materials gain electronic conductivity through the conducting backbone and CPs obtain excellent biocompatibility, sensitivity to environmental stimuli and controllable antifouling properties via multifunctional zwitterionic side chains. Unique properties from two distinct materials (conducting materials and zwitterionic materials) are integrated into one material without sacrificing any properties. This platform can potentially be adapted for a range of applications (e.g. bioelectronics, tissue engineering, wound healing, robotic prostheses, biofuel cell, etc.), which all require high performance conducting materials with excellent antifouling/biocompatibility at complex biointerfaces.
