论文摘要
本文设计了分子收集发射机（TX）模型，其中球形TX的表面被不同尺寸和任意位置的异质受体覆盖。如果分子击中任何受体，它们会立即被TX吸收。在TX中，分子存储在TX通过膜融合过程连续生成和释放的囊泡中。考虑到从TX到RX的传播过程中透明的接收器（RX）和分子降解，我们得出了TX吸收的分子释放速率和分子的比例以及RX处的接收信号。值得注意的是，这种分析结果适用于不同数量，大小和受体位置，并且通过基于粒子的模拟来验证其精度。数值结果表明，不同的囊泡产生速率导致TX吸收的相同数量的分子，但是不同的峰在RX处接收了信号。
This paper designs a molecule harvesting transmitter (TX) model, where the surface of a spherical TX is covered by heterogeneous receptors with different sizes and arbitrary locations. If molecules hit any receptor, they are absorbed by the TX immediately. Within the TX, molecules are stored in vesicles that are continuously generated and released by the TX via the membrane fusion process. Considering a transparent receiver (RX) and molecular degradation during the propagation from the TX to the RX, we derive the molecule release rate and the fraction of molecules absorbed by the TX as well as the received signal at the RX. Notably, this analytical result is applicable for different numbers, sizes, and locations of receptors, and its accuracy is verified via particle-based simulations. Numerical results show that different vesicle generation rates result in the same number of molecules absorbed by the TX, but different peak received signals at the RX.
