US Patent:

51564068, Oct 20, 1992

Filed:

Sep 12, 1990

Appl. No.:

7/581361

Inventors:

Cordelia Johnson - Lindenwold NJ
Lawrence Johnson - Lindenwold NJ

International Classification:

A63F 300

US Classification:

273248

Abstract:

A board game apparatus including a playing board having a surface with a plurality of contiguous rows of spaces, a plurality of designated spaces for initial positioning of sets of game pieces as well as a plurality of distinguishable finishing zones. The game apparatus is adapted with a combination of chance devices (1) Spinner Assembly and Chips (2) Dice. Wherein, multiple game pieces are advanced on the playing surface by the spin of the wheel or response to dice to determine the number of spaces the player moves on the game board. The players may at their own option either spin the wheel or toss the dice in an effort to decide which player opens the game. To win one of the players must succeed in placing all of their game pieces in scoring positions avoiding the obstacle members on the game board.

US Classification:

436501, 536 231, 977774, 977902

Abstract:

A signal-off-quantum-dot-based sensor for detecting the presence of a target molecule comprising: an aptamer probe having a nucleotide sequence which specifically interacts with the target molecule by sequence-dependent interaction, wherein the aptamer probe is sandwiched between (a) an oligonucleotide which is immobilized on the surface of a quantum dot (QD), and (b) a fluorophore-labeled oligonucleotide, wherein when the sensor is excited by an energy source: (i) in the absence of specific interaction between the target molecule and the aptamer probe, a baseline signal is emitted, and (ii) in the presence of specific interaction between the target molecule and the aptamer probe, a detection signal is emitted, wherein the baseline signal is greater than the detection signal, whereby the presence of the target molecule is detected.
