While numerous studies have quantified biomolecular adsorption to Au NPs in terms of equilibrium binding constants, far less is known about biomolecular orientation on nanoparticle surfaces. In this study, the binding of the protein α-synuclein to citrate and (16- mercaptohexadecyl)trimethylammonium bromide (MTAB)-coated 12 nm Au NPs is examined by heteronuclear single quantum coherence NMR spectroscopy to provide site-specific measurements of protein−nanoparticle binding. Molecular dynamics simulations support the orientation assignments, which -

Name Synopsis Description Options
UMOUNT(8) System Administration UMOUNT(8) NAME umount − unmount file systems SYNOPSIS umount −a [−dflnrv][−t fstype][−O option...] umount [−dflnrv]{directory|device}... umount −h|−V DESCRIPTION The umount command detaches the mentioned file system(s) from the file hierarchy. A file system is spec- ified by giving the directory where it has been mounted. Giving the special device on which the file system livesmay also work, but is obsolete, mainly because it will fail in case this device was mounted on more than one directory. Note that a file system cannot be unmounted when it is ’busy’ - for example, when there are open files on it, or when some process has its working directory there, or when a swap file on it is in use. The offending process could evenbe umount itself - it opens libc, and libc in its turn may open for example locale files. Alazy unmount avoids this problem, but it may introduce another issues. See −−lazy description below. OPTIONS −a, −−all All of the filesystems described in /proc/self/mountinfo (or in deprecated /etc/mtab) are un- mounted, except the proc, devfs, devpts, sysfs, rpc_pipefs and nfsd filesystems. This list of the filesystems may be replaced by −−types umount option. −A, −−all−targets Unmount all mountpoints in the current namespace for the specified filesystem. The filesystem can be specified by one of the mountpoints or the device name (or UUID, etc.). When this option is used together with −−recursive,then all nested mounts within the filesystem are recursively un- mounted. This option is only supported on systems where /etc/mtab is a symlink to /proc/mounts. -
