Gold conjugate-based liposomes with hybrid cluster bomb structure for liver cancer therapy.

abstract：:Titanium surfaces with micro-nano hybrid topography (nanoscale nodules in microscale pits) have been recently demonstrated to show higher biological capability than those with microtopography alone. On the other hand, UV treatment of titanium surfaces, which is called UV photofunctionalization, has recently been intro...
