In this paper, we consider a molecular relay channel in which signal molecules are transmitted by a sender of communication, propagated, amplified, removed in the channel, and sensed by the receiver of communication that decodes the signal molecules. To understand and characterize the communication capacity of the molecular relay channel, we develop an information communication model that consists...
A concept of three modules micro smart quantitative polymerase chain reaction (3M2sqPCR) is proposed and designed. The main design philosophy is to meet the ever increasing challenge of low cost, light-weighted, portable and real-time sensitive detection PCR system. The system consists of three modules: the micro-heater module, the reaction cell module and the electrochemical detection module. Experiments...
Contemporary ubiquitous devices unleash the boundary of one-to-one human-computer interaction, e.g., it has become a de facto style of facilitating social events that users use several distributed devices through multimodal interaction. How we will produce the ubiquitous devices for people to access multimodal media in different context is an interesting yet challenging problem? In this paper, we...
In this study, urease was immobilized on chitosan beads via a saccharide-concanavalin A binding. Similarly, the covalent immobilization of urease using glutaraldehyde was also studied for comparison. The aim of the study was to compare the two immobilization method in terms of their optimum temperature, thermal stability, optimum pH and pH stability and also, Michaelis constant(Km) of two immobilized...
In this paper, a class of molecular communication media is formalized, in which senders and receivers communicate by second messengers. Second messengers in the communication medium are released by senders of communication, propagated, amplified, removed in the medium, and sensed by receivers of communication that in turn decode the second messengers. Based on generalization of intracellular molecular...
Although molecular signaling of phosphorylation/dephosphorylation-proteins and GTPases has been extensively studied in molecular biology, it is still an open problem as to how information be coded in these molecules for molecular communication. In this paper, we propose a new channel coding algorithm based on signaling pathways in cells, extending our previous work on source codes to channel codes...
In this paper, we propose a new encoding algorithm and its corresponding decoding algorithm, which are designed by biomolecular computation based on the signaling pathways of Rho family GTPases. These algorithms can carry out encoding/decoding processes that are capable of correcting possible errors, and are expected to be realized by corresponding engineered cellular pathways according to their biochemical...
