MQ-SC might be one of the few techniques that can identify the formation of clusters made of the same species, here phosphates, that do not have distinguishable spectroscopic signatures between the coupled species. For clusters that cannot be isolated and/or are too small or with too little contrast to be captured by electron microscopy or various light scattering techniques, MQ-SC might in fact be the only approach to identify the minimal number of coupled phosphates in the cluster. MQ-SC is not a perfect experiment for ultimate quantification, but when it comes to a cluster of species with identical signal in solution state, there is no good alternative option. We have shown a great improvement in the method for analyzing MQ-SC data; by using more catered multi-cosine fitting, improved confidence in the minimum bound, highest visual MQCO can be achieved. In future studies, performing spin counting experiments on prenucleation cluster species at lower concentrations than as found in this paper would require conducting more scans. In this study we showed that increasing the molecular order increased the measured MQCOs for both powdered and vitrified solutions. Asymmetric molecular systems may require additional sample preparation optimization under vitrified conditions in order to mitigate CSA relaxation effects, such as electric field exposure for aromatic systems as demonstrated here. We show that one can go down to sub milimolar concentrations for a proposed calcium phosphate prenucleation cluster and still extract an MQCO order of 6. MQ-SC opens the door for extracting quantitative information at newfound atomic-scales in dynamic systems. Spin counting experiments can be applied in the future to test various nonclassical growth models, such as further examination of the calcium phosphate nucleation pathway with simplification of our simulated body fluid recipe. Shedding light on calcium phosphate assembly will pave the path for future bone and biomimetic material technologies and potentially identify a source of mammalian information storage
