Complex objects, recognition

The development of highly selective chemical sensors for complex matrixes of medical, environmental, and industrial interest has been the object of greate research efforts in the last years. Recently, the use of artificial materials - molecularly imprinted polymers (MIPs) - with high recognition properties has been proposed for designing biomimetic sensors, but only a few sensor applications of MIPs based on electrosynythesized conductive polymers (MIEPs) have been reported [1-3].

Concerning the required instrumentation, usually conventional active and passive optical components are employed however, their complexity can vary according to the proposed objectives. Two main parts can be distinguished the recognition element, which includes the selective reagents, the intermedi-... 

We wished to develop a macroscopic model of the interactions between molecular ligands and receptors. Molecular recognition is a broad subject that describes selective assembly in chemistry and biology, with examples from DNA-protein complex formation to asymmetric catalysis. The principle behind molecular recognition dictates that the molecules that mate have complementary shapes and interfacial characteristics. Our extension of this principle to the mesoscale involved the self-assembly of objects that matched both... 

A careful and objective analysis of recent decisions both in the review tribunals of the Patent Office and in the courts, and particularly in the Court of Customs and Patent Appeals, indicates that there is an ever-increasing awareness of the complex problems uniquely peculiar to the chemical and related arts. The judiciary before whom the majority of contested cases are brought on appeal have unusual sophistication and expertise in the highly complex technical areas embracing the broad spectrum of chemistry and the chemical sciences. There is encouraging evidence of growing recognition that the interim results of research may properly lay claim to patent protection. A realistic treatment of the utility question in chemical cases appears to be more the rule. 

Progress in contemporary analytical chemistry is often connected with miniaturization of working scale however, this does not generally mean improvement in detection limits. It is necessary to mention that electronic systems for automatic recognition of complex systems can provide qualitative information about the studied object at the 10 % level.
