This book is a pioneering work dedicated to the concept of "transmattering," which redefines our understanding of matter as a dynamic and transformative force. Through an autoethnographic lens, the author navigates the intricate relationships between human, post-human, and non-human entities, offering a fresh perspective on the ontological and epistemological dimensions of matter. The book investigates key topics such as the liminal conditions of transmattering, the role of bio art as an evocative narrative, and the genetic transmattering processes within biological laboratories. Each chapter provides a detailed analysis of these themes, drawing on the author's personal experiences and the latest research in New Materialism and Science and Technology Studies (STS). Readers are invited to explore critical questions about identity, agency, and the boundaries of life, as the author weaves a narrative that challenges traditional notions of matter and existence.
