A compact, low cost, wearable naphthalene dosimeter using Molecularly Imprinted Polymers (MIPs)

In this proposal, Intelligent Automation, Inc. (IAI) and the Applied Physics Laboratory at John Hopkins University (JHU/APL) detail the development of a small, rugged, low cost and wearable dosimeter that measures individual’s exposure to naphthalene. The key innovations of the proposed dosimeter include: a) the use of a miniature, low- cost and commercially available mass- sensitive transducer to ensure the high sensitivity of the dosimeter; and b) the use of Molecularly Imprinted Polymers (MIPs) receptor coatings to greatly enhance the sensor selectivity, and c) the design of a compact, low- cost, low power consumption circuit for data acquisition and analysis. Consequently, the proposed sensor has the following merits: a) small, wearable and low cost, b) high sensitivity and selectivity, c) long lasting serviceability, d) automatic data acquisition and interpretation, and e) reusable.
