Welcome to the first issue ofMetallomics: Integrated Biometal Science.The study of metals in biological systems is an increasingly important area of research. Metallomics is a newly emerging scientific field that is receiving great attention as a new frontier in the study of trace elements in the life sciences. It is a global discipline encompassing many areas including biology, chemistry, geology, medicine, physics, and pharmacy.As this field brings together researchers from such diverse areas, we anticipate thatMetallomicswill help to bridge the gap between researchers from different backgrounds so that ideas can be shared and the field progresses to the benefit of all. Our journal will serve as a focus for the community of metallomics researchers to come together and gain new perspectives and insights. It is our aim to reflect the interests of the emerging community and to support you as your community grows.We would like to acknowledge the work of those whose vision has led to the establishment of this field, including Bob Willams (R. J. P. Williams,Coord. Chem. Rev., 2001, 216–217; 583–595), Hiroki Haraguchi (H. Haraguchi,J. Anal. At. Spectrom., 2004,19, 5–14) and Joanna Szpunar (J. Szpunar,Anal. Bioanal. Chem., 2003,378, 55–56), and to all those who continue to contribute to the emergence of metallomics, without whom we would not be launching this exciting new journal.
