  • Publication number: 20210395906
    Abstract: There is disclosed an electrochemical deblocking solution for use on an electrode microarray. There is further disclosed a method for electrochemical synthesis on an electrode array using the electrochemical deblocking solution. The solution and method are for removing acid-labile protecting groups for synthesis of oligonucleotides, peptides, small molecules, or polymers on a microarray of electrodes while substantially improving isolation of deblocking to active electrodes. The method comprises applying a voltage or a current to at least one electrode of an array of electrodes. The array of electrodes is covered by the electrochemical deblocking solution.

  • Patent number: 11185838
    Abstract: There is disclosed an electrode array architecture employing continuous and discontinuous circumferential electrodes. There is further disclosed a process for the neutralization of acid generated at anode(s) by base generated at cathode(s) circumferentially located to each other so as to confine a region of pH change. The cathodes can be displayed as concentric rings (continuous) or as counter electrodes in a cross pattern (discontinuous). In this way reagents, such as acid, generated in a center electrode are countered (neutralized) by reagents, such as base, generated at the corners or at the outer ring.

  • Patent number: 8373313
    Abstract: A switch for premises electrical circuits provides wireless control compatible with at least one home automation control system technology. A single switch design can operate two-, three-, and four-way circuits without alteration, and without recourse to coordinating remote switches. The switch includes processor functions for restoring a previous state after power interruption, and for establishing a state commanded during the power interruption. The switch uses two single-pole, single-throw relays for positive safety lockout, and adjusts relay actuation timing with reference to power waveform zero-crossing for contact arc reduction with inductive, tungsten, and capacitive loads.

  • Patent number: 7718579
    Abstract: A method for electrochemical removal of acid-labile protecting groups on an electrode microarray using an organic solution is disclosed. The solution comprises a hydrazine derivative and a salt in an organic solvent. The hydrazine derivative has at least one hydrazine group having at least one hydrogen. The hydrazine derivative provides acidic reagent when an electrode is active and isolates the acidic reagent to the area around the active electrode. The salt is an organic salt or ionic liquid having a concentration sufficient to provide electrochemical conductivity under an applied voltage. During the applied voltage, acidic reagent is generated, which removes acid-labile protecting groups thereby allowing continued addition of monomers to build a custom microarray of oligonucleotides, peptides, or other polymers.
