The subject invention concerns materials and methods for detecting nucleic acid sequences. One aspect of the invention concerns a silicon-based 'biochip' comprising nucleic acid immobilized thereon. In one embodiment, the silicon comprises microcavities. The nucleic acid to be assayed for the presence of one or more target nucleic acid sequences is immobilized on the silicon. A nucleic acid, such as an oligonucleotide probe, having a sequence substantially complementary to the target nucleic acid sequence can be used to detect the immobilized nucleic acid on the silicon. If the nucleic acid used for detection hybridizes with a target nucleic acid sequence, the hybridized sequences can be detected directly or indirectly. In an exemplified embodiment, the oligonucleotide probe can be labeled with a detectable label, for example, a fluorescent molecule. The subject invention also concerns methods for detecting a target nucleic acid using a silicon-based biochip of the invention.

DNA biochip and methods of use

Anti-RSV peptide and a segment thereof derived from a peptide sequence identified in the human RSV fusion protein precursor F0. Another anti-RSV agent is carboxylated gold nanoparticles. A method is provided for attaching peptides to the carboxylated gold particles to produce additional anti-RSV agents to prevent or inhibit infection by the respiratory syncytial virus (RSV) and related viruses, including the human immunodeficiency virus (HIV).
