    Adsorption of oligonucleotides A10, A25, A50 and A80 at the mercury/electrolyte interface.

  • Original language description

    The adsorption of the oligonucleotides A10, A25, A50 and A80 at the mercury electrolyte solution interface is studied. The oligonucleotides are adsorbed at a potential close to -0.5 V (versus Ag/AgCl reference electrode) but they are desorbed at one or two potential ranges depending on the number of adenine molecules. The effect of the waiting time at the potential of maximum adsorption is studied and this time is closely related to the desorption peak heights. The adsorption/desorption is studied at two oligonucleotide concentrations and at two temperatures. The potentials of the desorption peaks of all oligonucleotides studied have almost the same value, indicating that the desorption process is almost the same. Capacity time curves following potential jumps from the adsorption region to desorption potentials show that the desorption is a very fast process but is usually followed by a reorientation/readsorption of the molecules at the interface depending on the number of adenines.

    Adsorpce oligonukleotidů A10, A25, A50 a A80 na rozhraní rtuť/elektrolyt.

  • Czech description

    Je studována adsorpce oligonukleotidů A10, A25, A50 a A80 na rozhraní mezi rtutí a roztokem elektrolytu. Oligonukleotidy jsou adsorbovány v okolí potwenciálu -0,5 V (oproti Ag/AgCl referenční elelktrodě), ale jsou desorbovány v jednom nebo dvou rozsazíchpotenciálů v závislosti na délce oligonukleotidu. Je studován vliv čekací doby při potenciálu maximální adsorpce. Bylo zjištěno, že výška desorpčních píků závisí na tomto čekacím čase. Adsorpčně-desorpční děj byl studován při dvou koncentracích oligonukleotidů a dvou teplotách. Potenciály desorpčních píků všech studovaných oligonukleotidů byly téměř stejné. Po skoku potenciálu z oblasti adsorpce do oblasti desorpce byla měřena závislost diferenciální kapacity C na čase t. Z C-t křivek lze usoudit, že desoprce je velmi rychlý děj, po kterém obvykle následuje reorientace/readsorpce molekul v závislosti na délce oligonukleotidu.
