Translocation measurements of intact DNA strands with the ion channel α-hemolysin (α-HL) are limited to single-stranded DNA (ssDNA) experiments as the dimensions of the channel prevent double-stranded DNA (dsDNA) translocation; however, if a short oligodeoxynucleotide is used to interrogate a longer ssDNA strand, it is possible to unzip the duplex region(More)
We present the results of a search for unknown interactions that couple to mass between an optically levitated microsphere and a gold-coated silicon cantilever. The scale and geometry of the apparatus enable a search for new forces that appear at distances below 100  μm and which would have evaded previous searches due to screening mechanisms. The data are(More)
