“…Two factors can affect the broad use of TiO 2 as photocatalyst: (a) the solar spectrum contains only 7-10% of UV light, (b) the high recombination rate of the photoexcited electron-hole pairs in the irradiated particles limits the overall efficiency. These problems can be solved by changing the electronic structure of the photocatalyst by doping TiO 2 with transition metal ions [5,6].…”

“…However, the shortcomings of TiO 2 as conventional powder photocatalysts such as easy aggregation, high filtration cost and poor adsorption ability [8][9][10] have greatly limited its practical application. In order to achieve rapid and efficient removal of pollutants and easy manipulation in a total Contents lists available at ScienceDirect journal homepage: www.elsevier.com/locate/mssp photocatalytic process, an effective way is to load TiO 2 onto suitable adsorbents.…”

“…Nanosilica and nanosilicon, when present from agitating the liquid medicines in glassware, would add (a) biological amplification and adjuvant effects [34,35] and (b) the possibility of serving as drug delivery vehicles [36,37] for homeopathically-manufactured natural source nanomedicines. Plants can coat the surface of such nanostructures [38] and minerals can serve as dopants to modify nanosilica/silicon properties [39]. Thus, surface-modified nanosilica/silicon could convey unique amplified plant-or mineral-derived information into cells, just as plant-synthesized gold nanoparticles can do [40].…”

The purpose of the present paper is (a) to outline the self-organized, complex adaptive network nature of the organism as recipient of nanomedicines; (b) to propose several nonlinear endogenous amplification processes by which pulsed low doses of traditional, homeopathically-manufactured natural product nanomedicines may stimulate a return toward healthier function; and (c) to discuss their potential relevance to novel, but safer than conventional dosing strategies for contemporary nanomedicines. Homeopathy is an over 200-year-old system of complementary and alternative medicine (CAM) that uses low doses of natural plant-, mineral-, and animal-sourced nanomedicines. Homeopathic manufacturing is "green", with mechanical grinding in lactose and agitation in ethanol-water as primary reagents. Agitation within glass containers at room temperature may also contribute nanosilica and nanosilicon as drug delivery vehicles and biological amplifiers. The medicine selection is matched to the recipient organism's systemic patterns of dysfunction and pulsed in the timing of the discrete doses. Endogenous amplification processes within the recipient organism may involve hormesis, time-dependent sensitization, and/or stochastic resonance. Effects are adaptive and systemically diffuse, i.e., causally indirect, rather than pharmacological and local, i.e., direct. All of these nonlinear response processes require interaction of the nanoparticle (NP) dose with the organism as a complex adaptive system. The pulsed NP dose serves as a low intensity salient danger signal for the organism to make network-wide adaptive changes that can lead to healing. The historically safe therapeutic approach of homeopathic nanomedicine dosing avoids risks of high, continuous doses and cumulative toxicity that contemporary nanomedicine researchers are now trying to solve while using NPs as if they were conventional bulk drugs. Integrating the insights, technical procedures, and clinical dosing approaches from modern and homeopathic nanomedicine could lead to major advances in the field for more effective and safer translational applications.NPs in homeopathic medicines [3]. NP concentrations are low, but measurable [3]. Like modern manufactured NPs [13], homeopathicallymanufactured medicines in solution also can exhibit aging effects [9,14]. These nanomedicines are delivered either in ethanolic liquids or sprayed and dried onto lactose or lactose/sucrose pellets for oral administration.Homeopathic manufacturing materials and methods are inherently "green" [15,16]. Previous papers have addressed the striking similarities between modern top-down mechanical attrition procedures for making nanoparticles (NPs) [17] and historical homeopathic medicine manufacturing methods and materials [15,[18][19][20][21]. These similarities include mechanically grinding source materials in lactose for hours and repeatedly agitating ethanol-water solutions containing the source Citation: Bell IR, Sarter B, Koithan M, Standish LJ, Banerji P, et al.
