The present invention is directed to a coated biomedical device said micelle having a hydrophilic outer shell and a hydrophobic inner core, or a hydrophobic outer shell and a hydrophilic inner core said micelle comprised of a block copolymer having a HLB value ranging from about 1 to about 40. The method may include receiving, at a processor, a frame identified as speech and determining that the frame was mistakenly identified as speech based upon, at least in part, a voice activity detection algorithm. In a preferred embodiment, the polymers are substantially transparent to deep ultraviolet radiation, i. The frame includes a number of second sidewalls.
