This letter presents a novel atomic force microscopy (AFM)-based nanomanufacturing method combining the tip scanning with the high-precision stage movement to fabricate nanochannels with ladder nanostructure at the bottom by continuous scanning with a fixed scan size. Different structures can be obtained according to the matching relation of the tip feeding velocity and the precision stage movi...

While tremendous efforts have been made in investigating scalable approaches for fabricating nanoparticles, less progress has been made in scalable synthesis of cyclic peptide nanoparticles and nanotubes, despite their great potential for broader biomedical applications. In this paper, tunable synthesis of self-assembled cyclic peptide nanotubes and nanoparticles using three different methods, ...

This paper focuses on electroplating-based volumetric nanomanufacturing to create highly-structured multilayer metallic materials, with precisely designed characteristic lengths in the hundreds of nanometers but volumes of manufactured material in the macro range. This electroplating-based approach also enables batch fabrication of nanostructures. The fabrication relies on automated and repeate...

We report measurements of rapid ordering and preferential alignment in block copolymer films zone annealed below the order-disorder transition temperature. The orientational correlation lengths measured after approximately 5 h above the glass-transition temperature ( approximately 2 microm) were an order of magnitude greater than that obtained under equivalent static annealing. The ability to r...

Abstract Nanoparticles are rapidly emerging as promising vehicles for next-generation therapeutic delivery. These highly mobile nanomaterials exhibit large carrier capacity and excellent stability which, when combined with innate biocompatibility, have captured the focus of numerous research efforts. As such, the ability to deliver well-controlled subcellular doses of these functional nanoparti...

Abstract Rapid advancement over the past decades in nanomanufacturing has led to realization of a broad range nanostructures such as nanoparticles, nanotubes, and nanowires. The unique mechanical, chemical, electrical properties these have made them increasingly desired key components industrial commercial applications. As geometric dimension nano-manufactured products is on sub-micron nanomete...

This paper describes an atomic force microscope (AFM) based voltage-assisted electrospinning technique. Single nanofibers on substrates are prepared via simultaneous preparation and deposition. In this work, an AFM-based electrospinning process is developed to generate polyethylene oxide (PEO) polymeric single fibers with nanometer scale diameters. The results demonstrate the feasibility of thi...
