Abstract
Smoking articles which involve the use of amphiphile-modified sorbents are disclosed. The amphiphile-modified sorbent has at least one amphiphilic compound bound to an inorganic molecular sieve substrate. The amphiphile-modified sorbent selectively removes certain constituents from cigarette smoke, while maintaining other constituents, such as those that contribute to flavor. Methods for making cigarette filters and smoking articles using amphiphile-modified sorbents, as well as methods for smoking a cigarette containing an amphiphile-modified sorbent, are also provided.
