  • 3D DNA origami designed with caDNAno 
    Amoako, George; Ming, Zhou; RiAn, Ye; LiZhou, Zhuang; XiaoHong, Yang; Yong, Shen zhi (University of Cape Coast, 2013-06-04)
    For about three decades, DNA-based nanotechnology has been undergoing development as an assembly method for nanostructured materials. The DNA origami method pioneered by Rothemund paved the way for the formation of 3D ...
  • Assessment of nine micronutrients in jasmine 85 rice grown in Ghana using neutron activation analysis 
    Amoako, George; Sefa-Ntiri, Baah; Amoah, Samuel; Sackey, Samuel Sonko; Amuah, Charles Lloyd Yeboah (University of Cape Coast, 2020-09-28)
    The amount of micronutrients in food is a key factor that determines the health status of a person. The concentrations of nine micronutrients, Sodium (Na), Magnesium (Mg), Chlorine (Cl), Potassium (K), Calcium (Ca), ...
  • Characterization of potential direct recharge in the gold mining district of South-Western Ghana using the hydrus-1d computer code 
    Sam, Frederick; Amoako, George; Sefa-Ntiri, Baah; Twum, Anthony; Mensah-Amoah, P.; Tellam, John (University of Cape Coast, 2018-07-18)
    The mean annual potential recharge rate to the ground water system in the Tarkwa gold mining district of South Western Ghana, has been estimated for the period 1977 to 2001 by analyzing precipitation recharge in response ...
  • Comparison of structures and hydrophobicity of femtosecond and nanosecond laser-etched surfaces on silicon 
    Bao-jia, Li; Zhou, Ming; Zhang, Wei; Amoako, George; Chuan-yu, Gao (University of Cape Coast, 2012)
    The rough micro- and nano- scale hierarchical structures on surfaces of materials render the surfaces superhydrophobic. In this context, we obtain both microscale grating structures and nanoscale induced structures (with ...
  • Connecting dna origami structures into a designed and functionalized network 
    Amoako, George (University of Cape Coast, 2019)
    The versatility of the DNA origami approach of organizing nanoparticles at the nanometer scale, together with thiol chemistry have been used. These approaches were used to design DNA origami structures and to functionalize ...
  • Connecting DNA origami structures using the biotin streptavidin specific binding 
    Ming, Zhou A; Ye, Rian; Mensah-Amoah, Patric; Twum, Anthony; Sam, Frederick; Amoako, George (University of Cape Coast, 2015)
    This work made use of the strong interaction between biotin and streptavidin to connect designed DNA origami structures. The caDNAno software was used to design a 6 layer 3D origami cross-like structure. Selected DNA strands ...
  • Design and fabrication of water phantom for treatment verification in high dose rate (hdr) brachytherapy of the cervix 
    Avevor, Justice; Amoako, Joseph; Amoako, George; Tagoe, Samuel Nii (University of Cape Coast, 2019)
    The aim of this study is to design and fabricate a local anatomical water phantom for dose distribution measurements during high dose rate brachytherapy of the cervix. Phantoms for dosimetry are used when there is a need ...
  • Determination of calorific values of coconut shells and coconut husks 
    Amoako, George; Mensah-Amoah, Patrick (University of Cape Coast, 2018-12-24)
    The coconut palm has a lot of uses including its use as composites and as fuels. In this work, we explored the use of a bomb calorimeter to determine the calorific values of coconut shells and coconut husks. A fixed sample ...
  • DNA origami as a tool to design asymmetric gold nanostructures 
    Amoako, George; Ming, Zhou; Eghan, Sackey; Sonko, Samuel (University of Cape Coast, 2017-12-06)
    DNA origami technology provides a versatile approach for the chemical assembly of gold nanostructures. In this study the bottom-up approach of self-assembly using DNA in the origami process has been successfully applied ...
  • DNA origami site-specific arrangement of gold nanoparticles 
    Amoako, George; Ye, Rian; Zhuang, Lizhou; Yang, Xiaohong; Shen, Zhiyong; Zhou, Ming (University of Cape Coast, 2013-08-14)
    Controlling matter at the nanoscale holds a lot of promise in nanotechnology. The DNA origami is promising if used as a template to design and arrange matter at the nanoscale. We have used the DNA origami approach to ...
  • Femtosecond laser structuring of materials: A review 
    Amoako, George (University of Cape Coast, 2019-04-03)
    In this review the interaction between femtosecond laser and matter with emphasis on silicon and some metals have been appraised. For silicon, spikes are produced as a result of interaction in the presence of background ...
  • Micro-punching process based on spallation delamination induced by laser driven-flyer 
    Jianke, Di; Zhou, Ming; Li, Jian; Chen, Li; Zhang, Wei; Amoako, George (University of Cape Coast, 2011)
    In this article, we proposed a micro-punching process for microstructure on films based on laser driven flyer induced spallation delamination phenomenon at the interface between a film and its substrate. To validate such ...
